【摘要】：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。
[Abstract]:On the basis of static test and a large number of numerical calculations, a quick shearing and extrusion connection mechanism for intermediate billets is proposed, which can simultaneously complete the horizontal and relative motions of upper and lower scissors, thus realizing the rapid connection of intermediate billets. In order to explore the characteristics of the mechanism, based on the ADAMS dynamic analysis software, the multi-rigid body model of the connection mechanism is established, and the kinematic process of the mechanism is simulated, and the moving track and horizontal velocity change curve of the scissors on and under the connection mechanism are obtained. The structural design is carried out by using the objective function method with constraints in ADAMS. The optimization results ensure the connection thickness of the intermediate billet, improve the problems of the speed leading and lagging in the connection process, and contribute to the smooth realization of the connection process of the intermediate billet. The analysis and optimization method based on ADAMS lay a theoretical foundation for the structural design of rapid shearing extrusion joint equipment.
