自动抱夹横移机手部抱夹装置的动力学仿真分析

Dynamics simulation analysis on hand clamp equipment of automatic clamp lateral moving machine

以自动抱夹横移机手部抱夹装置为研究对象,利用UG软件建立各零/部件的三维几何模型,在ANSYS软件中建立各零/部件的有限元模型,并采用弹簧阻尼器单元COMBIN14建立各结合部的动力学模型,从而建立手部抱夹装置整体有限元模型,进行模态分析和谐响应分析,得到手部抱夹装置前六阶模态,识别手部抱夹装置的薄弱环节,为手部抱夹装置的优化设计提供科学依据。

By taking hand clamp equipment of automatic clamp lateral moving machine as the object, the 3D geometrical model of each component was established by using UG. The finite element model of components was established in ANSYS, and springdamper element COMBIN 14 was adopted to build the dynamic models of each joint, then the overall finite element model was established. Furthermore, modal analysis and harmonic response analysis were carried out and the first six frequencies and mode shapes were obtained. The weak points of hand clamp equipment were identified, which provided scientific basis for the optimization design of this structure.
