中文摘要：

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。

英文摘要：

Aiming at the problems that the large thrust of erecting mechanism and the high demand on carrying capacity of cylinder,the virtual prototype model is established by using the ADAMS software,the method of setting the size of the contact force to detect motion interference is proposed. Using the method,that joints pivot is parameterized,the maximum erecting force is regard as the objective function,the layout of joints pivot is optimized,the maximum force of electric cylinders in the erecting process is reduced. Aiming at the characteristics that its force is complicated and the stress distributed unbalanced in erecting process,the flexibility analysis on the stress of the triangular arm at the initial stage and the intermediate stage are carried out. The lightweight of the triangular arm is carried out by using topology optimization,so as to reducing the structural weight and the cost is saved.
