摘要
利用仿真分析软件Hypermesh和ANSYS对某新型常闭液压钳制器进行有限元仿真,分析其受力情况。通过仿真分析,发现支点长柱长度太短,长柱两端应力集中非常严重,延长支点长柱的长度能够有效改善应力集中的情况。同时通过仿真获得了常闭液压钳制器预紧力与钳制力的关系曲线,及预紧力为35 416 N时液压与钳制力的关系曲线,获得满足要求的钳制器维持开闭状态所需螺栓预紧力和液压的大小,为钳制器的研制提供依据。
Finite element simulation is been used on stress ansysis of a new closed hydraulic clamping device. It is shown that the long supporting column is too short that the stress concentration has occurred in both ends of the column. To improve this performance the lengthening of the column has been applied. The relation curve of pre-tightening force against clamping force and the curve of hydraulic against clamping force at 35416N pre-tightening force can be obtain through simulation. Therefore the required pre-tightening force and the hydraulic for keeping the device closed can be derived.
