汽车变速箱的扭震模型。可以用来描述变速器的振动特性，本人自己编写的。-very perferct model of the gear box.

轿车变速器速比主要程序，可以直接应用，也可以修改为自己需要的模型在应用-Car transmission speed ratio main proceedings, can be applied directly, but also can be modified to model their needs in the application

采用4 挡变速器参数画出C 曲线。 其中，横坐标“燃油经济性”采用NEDC 循环行驶工况油耗，纵坐标“动力性”采用0~80km/h 原地起步加速时间；主传动比的值分别为4.82、5.3、5.83、6.12 和6.43。(The C curve is drawn by the parameters of the 4 gear transmission. Among them, the "fuel economy" of the transversal "fue
