摘要

搭载E-CVT的油泵具有提供冷却润滑流量、制动流量的作用。为研究摆线泵作为E-CVT液压系统动力源的使用特性，基于理论分析建立其数学模型，并利用AMESim平台搭建系统级（包括信号域、液压域、机械域）的多域仿真模型，通过实验数据验证了模型可靠。基于仿真模型动态研究油温、转速、负载压力对容积效率以及流动特性的影响，同时，将该模型搭载过滤器、油底壳及管道，仿真预测该油泵在E-CVT应用中的低油温启动失效，为后续油泵电机相关策略设计提供参考依据。

Abstract

The oil pump equipped with E-CVT has the function of providing cooling lubrication flow and brake flow.In order to study the use characteristics of cycloidal pump as the power source of E-CVT hydraulic system，the mathematical model is established based on theoretical analysis，and the multi-domain simulation model including signal domain，hydraulic domain and mechanical domain is built by AMESim platform.The model is verified by experimental data.Based on the simulation model，the effects of oil temperature，rotation speed and load pressure on volumetric efficiency and flow characteristics are dynamically studied.At the same time，the low oil temperature start failure of the oil pump in the E-CVT is predicted by the model connection filter，oil sump and pipeline，which provides a reference for the subsequent fuel pump motor related strategy design.
