| Abstract: | Electric drive gearbox is the key part of electric drive system for pure electric car, reasonable and effective lubrication of electric drive gearbox is crucial. In this paper, Smoothed Particle Hydrodynamics(SPH) is used to simulate the lubrication of electric drive gearbox. The PreonLab, a software based on SPH method, is utilized to simulate the lubrication of the two different speed conditions. The results of post-processing show that the simulation results are in good agreement with the test results. Both the feasibility and the validity of the method used for simulating the lubrication of gearbox are verified. |
