钢管夹持机构的模态分析与优化

Modal Analysis and Optimization of Steel Pipe Clamping Mechanism

摘要: 针对某钢管夹持机构的振动问题，本文应用SolidWorks三维建模软件对钢管夹持机构实体进行简化建模，采用Workbench有限元软件对钢管夹持机构进行模态分析，计算并分析了其前四阶固有频率和模态振型。在此基础上，对其结构形状，尺寸参数和固定端支撑方式进行了定向优化，并将优化前后固有频率改变进行了对比。结果证明改变结构形状尺寸和固定端支撑方式对优化机构动态特性具有一定可行性。

Abstract: Aiming at the vibration problem of a steel pipe clamping mechanism, in this paper, SolidWorks was used to simplify the model of the clamping mechanism for steel tubes. Workbench was applied to analyze the modality of the clamping mechanism for steel tubes, and the first 4 natural frequencies and mode shapes were calculated and analyzed. The structure, the parameters of size and fixed support were optimized, and the natural frequency changes before and after optimization were compared. The results show that it is feasible to optimize the dynamic characteristics of the mechanism by changing the shape and size of the structure and the support method of the fixed end.
