For instance,in the automotive industry, gearboxes can contribute to theoverall efficiency of the system and promote lower fuelconsumption and emissions, both allowing an optimizationof the whole system and reducing their own power losses.
In many circumstances a better efficiency corresponds tolower operating temperatures and to a higher reliability ofthe systems, which can be related to the final profit, likein industrial applications, or even to the success, like forinstance in motorsport racing.
Improving the efficiency istherefore a main issue also for the gearbox manufacturers,and the availability of methods and tools to forecast thebehavior with respect to lubrication and power losses sincethe beginning of the design phase strongly contributes tothe goal.
In the years, many empirical models were derived fromexperimental tests and have represented the only availabletool for such purpose, but today, thanks to the recent de-velopments in the computer science, numerical approachesallow a more accurate modeling of the physics behind thepower dissipation and also allow a description of the oilflow inside a gearbox, which is fundamental with respectto the reliability of the components of the transmission.
Both approaches, either derived from experimental tests or based on numerical simulations, have advantages and draw-backs.
For each single case and problem, d epending on thespecific condition, the most appropriate model is not alwaysthe same. In this paper a rev iew of the different availabletools is proposed, describing critically the properties of thesingle approaches in order to understand when each of themshould be preferred.
The review also includes the latest de-velopments by the authors, which have not been previouslypublished yet. When the majority of the contributing factors are taken into account gearbox and gears design, rotational speed, oil properties, oil level, etc , the nature of the environment surrounding the gears results in a difficult task to formulate a fluid mechanics based model.
Therefore, several of the published works are empirical or semi- empirical analysis and few numerical approaches appear thanks to the recent developments in the computational fluid dynamics .
Torque loss in FZG-A10 gears lubricated with axle oils. The efficiency of transmission must be considered. The literature   have proposed the strategies to calculate the power loss of gears.
The output torque or speed can be calculated with the following expression A novel coaxial multi-mode hybrid transmission system for mining trucks.
Given that hybrid electric vehicles could significantly reduce fuel consumption, and mining trucks are much more sensitive to energy conversion efficiency, it is essential to develop a hybrid system, which could meet both the specific requirements of the structure of mining trucks and the needs for overall efficiency improvements.
In this paper, a novel multi-mode transmission system, which is composed of an engine, two motors, one planetary gear set, and a parallel transmission structure, is proposed.
The planetary gear set serves as a power-split device, and the parallel transmission structure can make the engine and motor work in the high-efficiency area both in low-speed and high-speed conditions.
Due to the flexibility of the proposed system, five power-flow modes can be implemented, and they are illustrated with a specially designed rule-based energy management strategy.
To validate the effectiveness of the multi-mode transmission system, dynamic programming is used to assess the fuel consumption during the given driving cycle without considering drivability.
The simulation results reveal that the proposed multi-mode transmission system owns better fuel efficiency for mining trucks compared with highly regarded Toyota Hybrid System and conventional automated manual transmission system.
Lubrication characteristics of gear after shot peening base on pellet model. High-speed heavy-load spiral bevel gears put forward high requirement for flexural strength; shot peening is a technique that greatly improves the bending fatigue strength of gears.
During shot peening, a large number of fine pellets bombard the surface of the metal target material at very high speeds and let the target material undergo plastic deformation, at the same time strengthening layer is produced.
Spiral bevel gear as the object of being bombarded inevitably brought the tooth surface micro-morphology changes. In this article, we aim to reveal the effect of microtopography of tooth shot peening on gear lubrication in spiral bevel gear, try to establish a reasonable description of the microscopic morphology for tooth surface by shot peening, to reveal the lubrication characteristics of spiral bevel gears after shot peening treatment based on the lubrication theory, and do comparative research on the surface lubrication characteristics of a variety of microstructures.
Both steady state and dynamic simulations were performed at different lean angles and with three wheel profiles. More in detail, steady state simulations were performed adopting a rotating reference frame MRF  coupled with a solver specifically thought for incompressible flows.
Transient simulations were performed by partitioning properly the spatial computational domain, by setting as rotating a part of the mesh and adopting arbitrary interfaces AMI .
In motorcycle competitions, aerodynamics plays a fundamental role. In order to improve the performance of racing motorbikes, different front-wheel geometries have been studied by means of numerical CFD simulations.
Different lean angles were analysed for each geometry and the air motion-field were calculated. The considered geometries range from standard spoked design to solid wheels.
This open-source code was selected because, like all the computer programs of this type, it allows a higher flexibility with respect to any close-source commercial software, allowing a customization of the code by implementing specific models for the analysis of the physical problem of interest and also, at the same time, a higher parallelization of the computations.
Steady-state simulations were performed using a rotating reference frame MRF while, for the transients, a partially-rotating mesh was adopted, thus taking advantage of the internal sliding interfaces AMI.
Drag, lift and force-moments have been calculated with the aim of examining the stability and manoeuvrability of the different configurations.
The high costs of wind-tunnel tests act still as a deterrent to an experimental-driven aerodynamic design of vehicles, but in the last years CFD modelling gives an important contribution in bypassing this problem and to widespread a more aware use of some design solutions.
Concerning in particular the motorcycles, the main contributors to aerodynamic forces in such a vehicle are well-know and are: Burke  and Lukes et al  tried to identify the most relevant contributions to the overall aerodynamic resistance.
Tew and Sayers  have compared the aerodynamic performance of optimized and traditional wheels. Kyle and Burke  observed a significant drag reduction for rotating wheels with respect to stationary ones.
The same trend was observed by Fackrell and Harvey  for car tires. Few examples of CFD applied to study the air flow around a rotating wheel in contact with the ground can be found in the actual scientific literature.
Wray  performed numerical simulations to investigate the effect of the yaw angle on the drag and lift forces.
Godo et al  observed a transition from the expected downforce to a lift force at a yaw angle between 5 and 8 degrees. A comprehensive study of the flows around bike wheels and the related forces was made by Godo el at .
Dualsphysics  and nanoFluidX , just to mention some of them, are examples of such kind of simulation tools. A mud pump is an important part of the equipment used for oil well drilling.
The automatic valves of the fluid-end produce the pumping effect. The valves consist of a movable body and a reaction spring.
The spring is designed in order to avoid leakage and prevent contact between the valve itself and the retaining cage. Its proper sizing depends on the operating conditions as well as the properties of the fluid.
The valve seat geometry significantly contributes to ensure the tight of the fluid-end. An aspect that should be carefully considered during the design of new geometries is the phenomenon of cavitation.
Cavitation consists in the development of vapour cavities in the liquid phase. Inside the cavities the pressure is relatively low. When subjected to higher pressure, the voids implode and generate an intense shock wave that promote the wear of the components i.
A deep understanding of the fluid behaviour is crucial for an effective design. Transient CFD simulations of the valve opening have been performed using a non-Newtonian fluid model able to describe the drilling muds.
After a deep literature review, the Herschel-Bulkley model was selected as the most suitable for emulating the drilling mud.
With the abovementioned approach, the reaction spring and design the valve seat to avoid premature wear phenomena were properly designed. Numerical analysis of the dynamic performance of aerostatic thrust bearings with different restrictors.
This study utilizes a dynamic mesh technology to investigate the dynamic performance of aerostatic thrust bearings with orifice restrictor, multiple restrictors, and porous restrictor.
An experiment, which investigates the bearing static load capacity, was carried out to verify the calculation accuracy of dynamic mesh technology.
Further, the impact of incentive amplitude, incentive frequency, axial eccentricity ratio, and non-flatness on the bearing dynamic performance was also studied.
The change law of dynamic stiffness and damping coefficient for porous restrictor was quite different from orifice restrictor and multiple restrictors.
The bearing dynamic performance increased significantly with the growth of axial eccentricity ratio, and the surface non-flatness enhanced dynamic performance of aerostatic thrust bearings.
Influence of oil injection methods on the lubrication process of high speed spur gears. Entscheidend ist zudem, sich ein Gewinnziel zu setzen.
Man kann aber auch festlegen, dass der im Gewinn stehende Trade erst aufgelöst wird, wenn ein charttechnisches Signal das nahelegt.
Egal, mit welcher Strategie Sie am Ende Gewinn erzielen wollen: Denn nur, wenn Sie mehr Geld verdienen als verlieren, sind Sie auf dem richtigen Weg.
Das klingt ziemlich banal, wird aber von vielen CFD-Einsteigern allzu gern unterschätzt. Profis überprüfen ihre Strategie in aller Regel nach einem festen Muster: Zunächst wird die Trefferquote ermittelt.
Sie ergibt sich, indem Anleger die Anzahl der mit Gewinn abgeschlossenen Trades durch die Gesamtzahl aller Trades dividieren. Das Gegenstück zur Trefferquote ist übrigens die Verlustquote eins minus Trefferquote.
Die Trefferquote allein sagt aber noch nichts über den Erfolg aus. Der Schlüssel zum langfristigen Erfolg liegt im Verhältnis der durchschnittlichen Gewinne zu den durchschnittlichen Verlusten, dem sogenannten Erwartungswert s.
Nur wenn der positiv ist, erwirtschaften Anleger auf Dauer eine positive Rendite. Je höher der Wert, desto besser. Den meisten Anlegern dürfte schnell klar sein, dass ohne ein sauber geführtes Tagebuch jedes CFD-Controlling zum Scheitern verurteilt ist.
Es hilft aber auch, immer wiederkehrende Fehler zu entdecken. Zudem ist es ein nützliches Werkzeug, um sich der eigenen Stärken bewusst zu werden.
Ein CFD-Tagebuch ist nicht zuletzt dazu da, sich selbst als Anleger zu disziplinieren und Bauchentscheidungen zu verhindern. Das allerdings wäre wie bei einem Lottogewinn reine Glückssache.
