基于ADAMS的平压平模切机全清废机构的建模与仿真

为研究一款平压平模切机全清废机构的工作情况,采用虚拟样机技术研究其运动特性.利用Pro/E建立仿真模型,导入ADAMS进行高低两种转速下的仿真.借助ADAMS强大的自动运动学和动力学解析功能得到了全清废机构主要构件的运动曲线.分析曲线发现较高转速下机构的凸轮与滚子在运动过程中发生脱离,运动出现失真.结果表明现有设计会造成机构运动失真,极大影响设备的运转稳定性可能导致振动和噪音等问题的出现,后续必须优化.

The Modeling and Simulation of the Fall-Clearing Mechanism of the Platen Die-cutting Machine Based on ADAM

In order to know the working condition of the fall-clearing mechanism of a platen die-cutting machine, Virtual prototyping technology was used to study the motion characteristic. The simulation model was built by u- sing Pro/E and the model was input to the ADAMS. The simulation was studied for higher and lower speed. With the help of automatic kinematics and dynamics analytic function, simulation curves of main mechanisms＇ motions were drawn. Analyzing the curves we can know that in the higher speed the cam and the roller will not contact, motion is not true. The results suggest that the design will make the motion failed and it may influence the stability, or may lead to the vibration and noise and so it need to be optimized .
