摘要
针对传统车辆传动系试验台造价高、搭建过程复杂以及开发周期长等问题,基于SimulationX开发了车辆传动系虚拟试验台。以拖拉机液压机械无级变速器为被试对象,结合拖拉机工作特性,建立了发动机及液压机械无级传动系统模型,设计了试验台虚拟测控系统。以H1段连续换入HM3段为例,在试验台上进行了仿真。对比结果表明:仿真结果和试验结果一致,所给出的传动系虚拟试验台方案可行,可为车辆传动系开发与改进提供虚拟试验平台。
Aiming at the problems of high cost,complex construction process and long development period in the traditional vehicle transmission system test bench,the virtual test bench of vehicle transmission system was carried out based on Simulation X. Taking the tractor hydro-mechanical continuously variable transmission( HMCVT) as the test object,combined with the tractor working characteristics,the models of engine and HMCVT system were established. The virtual measurement and control system of the test bench was designed.The transmission speed ratio was continuously changed from H1 to HM3 as an example,the simulation was carried out on the test bench. The research results show that the simulation results coincide with that of experiment,and the proposed scheme is feasible,which can provide a virtual test platform for the development and improvement of the vehicle transmission system.
