摘　　要：介绍变密度法并利用其建立落砂机的拓扑优化数学模型,以最小应变能为目标函数,用Hypermesh软件进行落砂机的拓扑优化,利用Hypermesh的后处理软件HyperView查看拓扑优化的结果,在满足强度的要求下,减轻了落砂机的质量,从而得出优化方案是合理的,对后期落砂机进行轻量化研究具有指导意义;在Adams中建立落砂机框体与砂箱的碰撞模型,设置Adams碰撞矩阵,得到落砂机框体的运动仿真结果,分析落砂机框体的运动情况,从有限元仿真的角度验证落砂机框体与砂箱的碰撞是一个非线性的过程,能够更真实地模拟落砂机的工况,考虑在碰撞过程中的惯性力对结构的影响。Introducing the Variable-density Method that be utilized to established the topological optimized mathematical model for Inertia Vibrating Knock-out Machine, with the minimum strain capacity for target function, topological optimizing the structure by Hypermesh, thus concludes that the optimization scheme is rational, this is going to be instructive to the structure design and improvement of the Inertia Vibra- ting Knock-out Machine. The impact model was built with ADAMS, and impact matrix was set, the result of simulation can be used to analyze Inertia Vibrating Knock-out Machine＇ s movement, verify the shakeout machine box body and the box collision is a nonlinear process.
