在静态试验及大量数值计算的基础上提出一种中间坯快速剪切挤压连接机构,可以同时完成上、下剪刀的水平运动和相对运动,从而实现中间坯的快速连接。为了探究该机构的特性,基于ADAMS动力学分析软件,建立了连接机构的多刚体模型,仿真模拟了机构的运动过程,求得了连接机构上、下剪刀的运动轨迹和水平速度变化曲线,利用ADAMS中带约束的目标函数法进行了结构化设计,优化结果保证了中间坯的连接厚度,改善了连接过程中速度超前、滞后的问题,有助于中间坯连接过程的顺利实现,基于ADAMS的分析和优化方法为快速剪切挤压连接设备的结构设计奠定理论基础。
Based on the static test and a large number of numerical calculations, a rapid shear-compression connection mechanism for intermediate billet is proposed, which can realize the horizontal and relative movement of the upper and lower scissors at the same time, so as to realize the quick connection of the intermediate billet. In order to explore the characteristics of this mechanism, a multi-rigid body model of the connecting mechanism was established based on ADAMS dynamic analysis software. The movement process of the mechanism was simulated. The trajectory and horizontal velocity curves of the upper and lower scissors of the connecting mechanism were obtained. The objective function method with restraint in the middle has the structural design. The optimization result ensures the connection thickness of the intermediate slab, improves the speed leading and lagging problems in the connection process, and is conducive to the smooth realization of the intermediate slab connection process. Based on ADAMS analysis And optimization methods laid the theoretical foundation for the structural design of rapid shear extrusion connection equipment.
