串联型液压混合动力车辆的参数匹配与动力性能仿真

Parameters Matching and Dynamic Simulation for Series Hydraulic Hybird Vehicle

为研究串联型液压混合动力车辆的动力性能,应用基于静液传动车辆的二次调节技术,对车辆主要元件进行参数匹配。运用AMESim建立物理模型,在Simulink中进行关键控制系统建模,并通过AMESim/Simulink联合仿真进行车辆的动力性仿真,验证部件参数匹配的效果。仿真结果表明,参数匹配合理,加速、爬坡动力性能优于同级别传统车辆,为搭建车辆性能模拟试验台架的关键元件选型提供了实用依据。

In order to study the dynamic performance of the series hydraulic hybrid vehicle, the main vehicle parameters are matched with the technology of secondary regulation. AMESim is used to set up the physical model while Simulink is used to model the key control system. The simulations of the vehicle dynamic performance were carried out. The results show that the parameter matching is reasonable, and the performances of accelerating and climbing are better than those of conventional vehicles at the same level. This also provided a kind of practical basis to select key components for the simulation test bench of the vehicle＇ s performance.
