槽轮机构的运动分析与优化设计

针对槽轮机构的机械特性,利用MATLAB计算了槽轮机构的运动参数并绘制了角速度和角加速度曲线。由计算结果和仿真运动曲线可知,槽轮机构的动力性能可用其角加速度来衡量。槽数越多,角加速度就越小,动力性能就越好。在相同转角和相同曲柄转速的情况下,槽数的增加可以提高槽轮机构运动的可靠性和传动平稳性,能使槽轮机构的动力性能得到有效改善。

Motion Analysis and Optimization Design of Geneva Mechanism

According to the mechanical characteristics of geneva mechanism, motion parameters were calculated and similar angular velocity and acceleration curves were plotted in the MATLAB environment. The calculation results and simulation motion curves show that the dynamic performance of geneva mechanism can be measured by the angular acceleration. The more the number of grooves, the smaller the angular acceleration, additionally, the dynamic performance can be better. In the condition of the same angle and crank speed, increase in the number of grooves can improve the motion reliability and transmission stability, this can improve the dynamic performance of geneva mechanism effectively.
