基于虚拟样机的打捆机链传动系统仿真分析

Simulation analysis of chain drive system based on virtual prototype

链传动系统是组成圆捆打捆机的关键部分,为研究其动力学特性,利用SolidWorks建立链传动系统的三维模型,导入ADAMS中进行仿真,得到链传动系统在实际工作中的受力情况、边界载荷和振动情况。利用ANSYS对链传动系统内、外链节进行模态分析,得到各阶固有频率以及相应的振型。对结果进行分析,链传动系统的内、外链节的固有频率远高于链传动系统工作时危险频率,因此验证模型的正确性。同时为该打捆机链传动系统的设计和研发提供参考。

The chain drive system is a key part of the round bundle.In order to study the dynamic characteristics of the system,the three-dimensional model of the chain drive system is established by SolidWorks.The model is imported into ADAMS,and the load,boundary load and vibration of the system are obtained.The use of ANSYS on the chain transmission system within the outer link,the modal analysis,get the natural frequencies and the corresponding modes.Through the analysis of the results,the natural frequency of the inner and outer chain link of the chain transmission system is much higher than the chain transmission system working in dangerous frequency,which verifies the correctness of the model.This paper provides a reference for the design and development of the chain drive system.
