基于Recurdyn成排矫直机换辊辊身锁紧拉爪刚柔耦合分析

Rigid-flexible Coupling Analysis of the Locking Jaws of the Changing Rollers of Recurdyn Row Straightening Machines

对高刚度成排矫直机的换辊锁紧拉抓系统进行运动学耦合仿真,通过对拉爪接触分析切向滑移分析,获取拉爪滑移与接触力有关联,将拉爪柔性化后,进行拉爪的应力场分析,结果表明接触情况接近于实际工况,对矫直机锁紧拉抓系统设计提供了理论依据。

The kinematic coupling simulation of the changing roller locking pull-grip system of the high-stiffness row straightening machine,through the tangential slip analysis of the contact analysis of the pulling claw,to obtain the pulling claw slip and the contact force has a correlation with the pulling claw,the pulling claw after the flexibilization of the pulling claw,the stress field analysis of the pulling claw,the results show that the contact situation is close to the actual conditions,the locking pull-grip system of the straightening machine provides the theoretical basis for the design of the locking pull-grip system.
