摘　　要：搭建了金属带式无级变速器传动系统的数学模型,并通过实例仿真分析了CVT速比变化特性对车辆加速度的影响。研究结果证明,CVT速比变化率能够在一定程度上影响车辆加速度,应当根据速比变化的方向适当地控制速比变化率。该项研究工作为CVT速比变化率的控制策略提供了理论上的依据和方法。The mathematic model of the metal pushed V -be lished, and the influence of CVT speed ratio variation on the ve through the example. The research result proves that the changing acceleration to a certain extent. As tLe result, the changing ing to the direction of the changing. Through for the control strategy of the CVT speed ratio It continuously variable transmission is estab- hicle acceleration is analyzed and simulated rate of the speed ratio affects on the vehicle rate of the speed ratio should be controlled accord- the research, the theoretical foundation and method are provided changing rate.
