摘　　要：目的设计一种合适的滑板曲线槽,以提高转膛体稳定性。方法应用凸轮机构运动原理,以滑板为主动件,转膛体滚轮为从动件,通过类比不同类型的曲线槽,对比其加速度、速度变化规律,选择加速度无突变、没有刚性冲击及柔性冲击的五次多项式运动规律进行设计。在三维软件中绘制好三维模型后,对其进行运动学仿真分析,对比转膛体滚轮在传统曲线槽与该种曲线槽约束下转膛体的运动稳定性。结果滑板曲线槽在运用五次多项式运动规律进行设计后,转膛体的运动稳定性得以提升,其中,角速度峰值由 1479.76 (°)/s 降到了 1023.70 (°)/s,降低了 30.82%;角加速度峰值由 3.3×105 (°)/s降到了 1.58×105 (°)/s,降低了 52.12%。结论应用五次多项式运动规律的曲线槽对提高转膛体运动稳定性有明显作用,为滑板的设计提供了参考。Objective To design a suitable slide curve groove to improve the stability of the revolving body. Methods The principle of motion of the cam mechanism was applied. With the driving slide as the active part and the revolving body roller as the follower, the acceleration and the speed change law of different curved grooves were compared. The fifth-order polynomial motion law without sudden change in acceleration or rigid impact and flexible impact was designed. After the model was drawn in 3D software, the kinematics simulation analysis was carried out to calculate the motion stability of the revolving body while its wheel was constrained by the traditional curved groove and the curved groove. Results It was found that the motion stability of the revolving body was improved after the curve groove of slide was designed with fifth-order polynomial motion law. The angular velocity peak was reduced from 1497.76 (°)/s to 1023.70 (°)/s, which was reduced by 30.82;the angular acceleration peak was reduced from 3.3×10 5 (°)/s to 1.58×105 (°)/s, which was reduced by 52.12 . Conclusion The curved groove with the fifth-order polynomial motion law has a significant effect on improving the stability of the rotating body, which provides a reference for design of the slide.
