基于Pro/E建立了后插式曲柄摇杆分插机构的三维模型,并进行了运动仿真模拟和动力学分析,参数设定为分插机构工作插次200次/min,主动轴转速为n=200r/min,运动时间为t=1.5s的情况下,得到秧针的运动速度图和加速度图,使得机构运动分析变得可视化、直观化和简单化,为分插机构的设计提供了方法,有利于机构参数的合理选择,同时降低分插机构的研发周期,提高工作效率.利用Pro/E找出了分插机构的振动源和受力情况,结果指出,曲柄添加平衡块和减轻摇杆质量有利于减小冲击和振动.
Based on Pro / E, a three-dimensional model of the plug-in crank-rocker add-on mechanism was established. The kinematic simulation and dynamics analysis were carried out. The parameters were set as the plugging mechanism working plug 200 times / min, the drive shaft speed n = 200r / min, the movement time is t = 1.5s, we get the velocity and acceleration maps of the seedling, which make the movement analysis of the mechanism visualized, visualized and simplified, which provides a method for the design of the substation mechanism , Which is beneficial to the rational choice of mechanism parameters and reduce the R & D cycle and improve the work efficiency of the mechanism.In addition, Pro / E was used to find out the vibration sources and stress conditions of the ramification mechanism. The results showed that adding balance mass and relieving vibration Rod quality helps reduce shock and vibration.
