摘要

以采埃孚9速自动变速器（9HP48）为研究对象，明确了自动变速器各挡位中动力传递的线路，对各挡位的传动比和转矩比（考虑摩擦损失）进行理论推导，并运用克莱伊涅斯公式计算了9个前进挡和1个倒挡的传动效率。为了验证理论推导的正确性，使用AMESim仿真软件建立自动变速器的仿真模型，通过仿真计算得到每一挡位传动比和传动效率数值，对比发现，仿真结果与理论分析结果相吻合。仿真结果验证了理论推导的正确性，也为优化自动变速器传动方案提供了基础。

Abstract

Taking the ZF 9-speed automatic transmission (9HP48) as the research object，the power transmission line in each gear of the automatic transmission is clarified. The transmission ratio and torque ratio (considering friction loss) of each gear are theoretically derived. The М.А.Крейнeс formula is used to calculate the transmission efficiency of 9 forward gears and 1 reverse gear. To verify the theoretical derivation，AMESim simulation software is used for building the simulation model of the automatic transmission. The transmission ratio and transmission efficiency values of each gear are obtained through the simulation calculation. The simulation results are consistent with the theoretical analysis results. The simulation results verify the correctness of the theoretical derivation and provide a basis for optimizing the automatic transmission scheme in the future.
