摘要
钳臂是重载操作机夹持机构的重要组成部分,其力学性能和疲劳性能直接影响着操作机的正常使用功能。本文针对重载锻压操作机钳臂结构进行了典型工况下的力学性能分析,在此基础上对钳臂结构进行了多工况拓扑优化,给出了材料布局以及力的最优传递路径,并进一步进行尺寸优化。结果表明,优化后的钳臂结构在保持良好力学性能的同时,减少了材料用量。
The clamp is an important part of the heavy-duty forging manipulator, whose mechanical properties and fatigue performance have much impact on the normal operation of the manipulator. In this paper, the mechanical properties of the clamp arm structure of the heavy forging manipulator under typical load cases are studied. The topology optimization of the clamp arm under multiple load cases are performed to obtain the optimal material distribution and force transmission path, based on which the size optimization is carried out. The results show that the material usage of the optimized clamp arm structure can be reduced while maintaining the good mechanical properties.
