Stability Analysis for Transverse Vibration of Roller Chain Drive

基于多体动力学理论,建立了滚子链传动系统横向振动动力学模型。该模型考虑了链条张力及链节转动惯性对链系统横向振动的影响。在此基础上,通过算例仿真,对滚子链系统横向振动固有特性进行了研究,并分析了不同边界激励条件对滚子链传动系统横向振动稳定性的影响。研究结论可为指导各种含链传动系统的机械装置的动态分析与设计提供借鉴。

Based on the multi-body dynamics theory,the dynamic model of transverse vibration of roller chain drive system is established.Effects of the chain tension force and the rotational inertia of the link on transverse vibration of chain system are considered.On this basis,the natural characteristics of transverse vibration of roller chain drive system is studied by simulation example.Additionally,effects of the different boundary excitation conditions on the stability of transverse vibration of roller chain drive system are analyzed.The conclusions can provide guidance and reference to the dynamic analysis and design of mechanisms with roller chain drive systems.
