摘要
基于虚拟样机技术和柔性多体动力学理论,综合运用三维建模、有限元分析以及多体动力学仿真等技术,建立了自动平压平模切机主切机构曲轴-连杆-肘杆-动平台系统三维刚柔耦合动力学模型,并对其动态特性进行仿真,得到了一个运动周期各部件运动及动力学响应曲线。结果表明,主切机构运行过程中没有"飞脱"和"腾跳"等现象发生。
Based on virtual prototype technology and the dynamics theory of flexible many-body systems,by comprehensive application of 3D modeling,finite element analysis and many-body dynamics simulation technique,etc.,3D rigid-flexible coupling dynamics model for die cut machine main mechanism crankshaft-connecting rod-knuckle-lever-moving platform was established.Simulation to its dynamic characteristics was performed,and the motion and dynamics response curve for each part in one motion period was obtained.The results show that each part of the die cut machine main mechanism keeps proper contact without any abnormal phenomenon throughout the whole operation process.
