基于COMSOL的滑轮应力分析

Analysis on the Stress of Pulley Based on COMSOL

通过建立滑轮模型,利用仿真软件COMSOL研究驱动滑轮中的应力分布情况。首先进行理论分析,定义滑轮的参数属性,通过边界坐标系来施加边界载荷,对滑轮工作时的应力情况进行参数化研究。利用正交实验法,研究了滑轮与带接触角、滑轮厚度、功率、滑轮转速、外径共5个参数对滑轮工作时Von Mises值的影响,对实验结果进行分析,确定出优化方案,从而为滑轮的设计及使用提供一定的参考。

By setting up the pulley model, the stress distribution in the driving pulley is studied by using the simulation software COM- SOL. In order to parameterize the stress condition of the working pulley, first of all, theoretical analysis is carried out to define the parameter properties of pulley, and boundary load is applied through the boundary coordinate system. Using the method of orthogonal experiment, studied diameter of pulley five parameters influence on pulley work impact indicators Von Mises value are studied. Five parameters are the contact angle, the pulley and belt pulley thickness, power, speed. Finally, the analysis of experimental results are analyzed, the optimum scheme is determined, it is as the reference of design and use of pulley.
