摘要
无级变速器(CVT)能够在一定范围内连续实现速度改变,适用范围宽,应用前景广。利用虚拟样机技术实现无级变速器的设计与研发,具有研发周期短,成本低,并且能够实现产品全生命周期管理。通过在多体系统优化仿真软件RecurDyn中建立CVT虚拟样机模型进行运动学和动力学分析和仿真,全面了解CVT各方面性能,并将仿真结果与理论计算结果对比,从而证明虚拟样机技术的可行性和先进性,并具有很大的推广价值。
Continuously variable transmissions （CVT）,achieving continuous speed changes within a certain range,have an extensive use and promising prospect of application.Based on virtual prototyping tech- nology,this design and research of CVT can realize product life cycle management with short development cycle and low cast.It conducts kinematics and dynamics analyses and simulation of the virtual prototype mod- el of CVT with RecurDyn,a multi-body system optimization simulation software, aiming at understanding the overall performances of CVT,and compares the simulation findings with theoretical calculation results to prove the feasibility and advance of virtual prototyping technology,which deserves extensive use.
