Modeling Calculation of Mini Car Transmission System Power Loss

通过对微型汽车传动系统各个部件功率损失的组成及形成机理的分析,建立了微型汽车传动系统功率损失的数学计算模型,并在Matlab/Simulink中进行仿真,最后用试验数据进行了验证。结果表明,所建模型的计算结果与试验值基本相符,该理论模型为汽车传动系统功率损失预测和传动系参数优化设计提供了依据。

Based on the analysis of composition and formation mechanism of each parts power loss of the mini car transmission system, the power loss mathematic model of the transmission system is established, then the simulation is car- ried out in Matlab/Simulink, at last, the model is verified by test data. The result shows that the model calculation results match experimental values generally, the theory basis for the transmission system power loss prediction and the optimiza- tion of auto transmission system is provided by the model.
