摘要
在对某型无级变速器夹紧力控制系统结构原理进行分析的基础上,采用键合图理论建立其数学模型,对该系统动态性能进行仿真。分析结构参数对系统阶跃响应时压力上升时间和超调量的影响,找出了对系统动态性能影响较大的结构参数,为系统动态性能的优化奠定基础。台架试验结果表明,所建立的夹紧力控制系统模型具有较高精度,仿真结果可信。
Based on an analysis on the working principle of the clamp force control system of a continuously variable transmission,a mathematical model for the system is established by applying bond graph theory,with which the dynamic performance of the system is simulated. The effects of its structural parameters on the pressure rise time and overshoot of system responses are analyzed,and the structural parameters having more obvious influences on system performance are found out,laying a foundation for system performance optimization. The results of bench test show that the model built has higher accuracy and the results of simulation are credible.
