摘要
针对过约束多体运动机构的动态受力分析难点,以一个具体的多曲轴运动平台为例,提出一种基于Pro/E中Mechanism仿真模块进行动态仿真的解决方法。在Pro/E中进行了3维建模;针对分析的重点,对系统模型进行了适当简化;并结合虚拟样机技术在Pro/E中的具体运用,对简化模型进行动态仿真;并运用仿真结果分析了各类因素对该机构运动及受力的影响,提出了优化设计方案。
Aiming at the problems of dynamic analysis on multi-body systems with redundant constraints, a solution based on the dynamic simulation in Mechanism module of Pro/E is proposed and illustrated with an example of a translational platform with multicrank. A three-dimensional model of the system is built simplified to fit the pivot in the research. Comprehensive dynamic simulation is performed based on the application of virtual prototyping technology in Pro/E. The factors which impact the motion and reacting forces of the platform are analyzed with simulation results. The optimized design is then considered.
