The ductility of PVC was enhanced after thermoplastic molding.In order to reduce the transmission error of PVC in the stepping process,the influence of dynamic transmission characteristics of synchronous belt-load mechanism in PVC clamping and stepping device on the transmission error of PVC was analyzed.Firstly,based on the Lagrange equation,the longitudinal vibration differential equation of the synchronous belt-load transmission mechanism in the generalized coordinate system was established and the excitation response was solved.Secondly,the rigid-flexible coupling simulation of synchronous belt-load transmission mechanism was solved based on ADAMS virtual prototype,and the dynamic characteristics of synchronous belt transmission mechanism was analyzed.Finally,based on the viscoelastic characteristics of the synchronous belt,the influence of different pre-load and the plate load on the transverse vibration,load dynamic linear displacement error and motion characteristics of the syn-chronous belt was analyzed,which provides a theoretical reference for the application of similar devices in the optimization of PVC transmission accuracy and stability.
