金属带式无级变速器在发动机变功率下的响应仿真

Response simulation of CVT under variable power condition of engine

利用仿真原理和 Matlab语言对金属带式机械无级变速器 (CVT)的自动变速功能进行了仿真分析研究 ,重点研究变功率时 CVT的响应 ,其结果表明 :金属带式 CVT比传统的有级变速器和自动变速器具有更加优良的性能 ,它的最大优点是操作简便 ,并能实现 CVT与发动机的最佳匹配。

Based on the controlling program in Matlab language some dynamic performance of metal pushing V belt continuously variable transmission (CVT) power is discussed in detalil and simulation on CVT′s auto speed change function is made,esp the response of CVT under variable power.The results of the study show that cars with metal pushing V belt type CVT can own better performance than those with traditional step transmission or auto speed change transmission.The main virtue of CVT is convenient and can be a best match for the engine.
