摘　　要：针对金属带式无级变速器(CVT)夹紧力控制不合理造成传动效率偏低问题,提出基于滑移率的夹紧力PID控制方法。基于金属带滑移传动理论,创建CVT动态滑移模型,设计安全因子PID控制器。为了验证此控制系统的有效性,进行了仿真实验。仿真结果表明,基于滑移率的夹紧力控制方法能有效降低目标夹紧力,提高传动效率。Concerning the problem of low transmission inefficiency of the metal V-belt type CVT due to improper clamping force,a PID control strategy of clamping force based on slip rate was presented.The CVT slip dynamic mathematic model was established and safe factor PID controller was designed according to the metal V-belt slip transmission theory.Simulation test was used to verify the control system effect.The result showed that clamping force control method based on slip rate could reduce object clamping force and improve the transmission efficiency.
