| 摘 要： | 在金属带式无级变速器的动态分析模型基础上,综合分析与速比变化相关的量,提出一种速变器处于蠕动滑移状态时的速比变化机理模型.采用MATLAB Simulink软件,以无级变速器实车测试工况作为仿真模型的输入,得到的仿真结果与实车实验数据一致性高.新模型克服了以往模型在速比变化过程中,速比变化率响应范围过大、速比变化率振荡的不足.

| Abstract: | It is important for continuously variable transmission (CVT) speed ratio control that gets to the bottom of the CVT shifting principle. In this paper, through analyzing the relative quantities of CVT shifting, a new shifting model is developed based on the CVT dynamic model. After the simulation analysis of new CVT shifting model made a measured condition as the input in the MATLAB\Simulink, it proved that this simulation using the new shifting model can get consistent results with the measurement data in car. And compared with CMM model simulation results, it can find two faults of CMM model: one is the shifting range is too lager; the other is the shifting rate oscillation, but the new variator shifting model can solve these problems. |
