摘要
目的针对翻转机构的功能和要求,设计由轮系组成的一种新型翻转机构。方法使用动力学仿真软件Adams建立动力学模型并进行仿真分析,得到其相应的动力学曲线和运动规律。结果翻转机构的转速降低1 r/min,弹药与翻转架的接触力降低5 N左右,翻转机构对弹药的径向力降低1 N左右。合理降低翻转机构的速度和减小接触刚度系数,可以有效地提高翻转机构的稳定性。结论Adams对多体机构的运动规律提供精确的预测。
Objective To design a new type of turnover mechanism composed by gear train according to the requirement of the function and design of turnover mechanism. Methods The dynamic model was established using the Adams software and the simulation analysis was conducted to obtain the corresponding dynamic curves and the motion pattern. Results The optimized result indicated that, when the rotational speed of the turnover mechanism reduced by 1 r/min, the contact force of the bullet against the roll-over stand reduced by about 5 N, and the radial force of the turnover mechanism against the bullet reduced by about 1 N. Reasonable reduce of the speed and the contact stiffness coefficient of the turnover mechanism can effectively improve the stability of the turnover mechanism. Conclusion The results showed that the Adams software can provide accurate prediction of motion pattern for multi-body mechanism.
