【摘要】：针对起竖机构推力大,驱动缸承载能力要求高的问题,利用ADAMS软件建立机构的虚拟样机模型,提出了设置检测接触力大小来检测运动干涉的方法;对铰支点采用参数化处理,以最大起竖力为目标函数,优化了铰支点的布局,减小了电动缸起竖过程中的最大受力。针对起竖过程中三角臂受力复杂,应力分布不均衡的特点,对三角臂进行了柔性分析,分析了三角臂在初始阶段和中间阶段的应力变化情况,运用拓扑结构优化方法对三角臂轻量化处理,减轻了机构质量,节约了成本。
[Abstract]:In order to solve the problem that the thrust of the vertical mechanism is large and the bearing capacity of the driving cylinder is high, the virtual prototype model of the mechanism is established by using ADAMS software, and the method of setting the detection contact force to detect the motion interference is put forward, and the maximum vertical force is taken as the objective function to optimize the layout of the hinge fulcrum and reduce the maximum force in the vertical process of the electric cylinder. In view of the complex force and uneven stress distribution of the triangular arm in the process of vertical lifting, the flexibility analysis of the triangular arm is carried out, and the stress variation of the triangular arm in the initial and intermediate stages is analyzed. The topological structure optimization method is used to quantify the triangular arm, which reduces the quality of the mechanism and saves the cost.
