基于ANSYS和ADMAS吊装输送机构传动轴的分析与优化

Analysis and Optimization of Transmission Shaft of Hoisting and Conveying Mechanism Based on ANSYS and ADMAS

利用ANSYS对吊装机构传动轴进行静力学分析,通过ADAMS对其进行动力学分析,以获得传动轴在标准工况和紧急刹车工况下的应力与变形的最大值。分析表明,传动轴的刚度及强度符合设计要求。为了进一步降低传动轴工作时的最大应力,采用响应面优化,对传动轴的结构进行优化,优化完成后其最大变形降低约5%,最大应力降低约20%,为后续类似设计提供参考。

This paper uses ANSYS to conduct statics analysis on the drive shaft of the hoisting mechanism,and conducts dynamic analysis on it through ADAMS to obtain the maximum stress and deformation of the drive shaft under standard operating conditions and emergency braking conditions.Analysis shows that the rigidity and strength of the drive shaft meet the design requirements.In order to further reduce the maximum stress of the drive shaft during operation,response surface optimization is used to optimize the structure of the drive shaft.After the optimization is completed,the maximum deformation is reduced by about 5%,and the maximum stress is reduced by about 20%,which provides a reference for subsequent similar designs.
