摘　　要：为了实现单停止往复运动,降低运动中的冲击,提高运动稳定性。分别利用多项式和谐波函数,施加相应的边界条件,解析了三种运动规律,其均可满足工程应用。根据运动在折返点处加速度可不为零的特性,得出的4-5-6-7-8多项式单停运动规律具有更好的动态性能。In order to realize the single dwell reciprocating motion,to reduce the impact during the motion and to improve the stability of the motion,using polynomials and harmonic functions respectively,applying corresponding boundary conditions,the three kinds of motion laws are analyzed,which can meet the engineering applications.According to the property that the acceleration is not equal to zero at the retrace point,the gained 4-5-6-7-8 polynomial function single dwell motion law has better dynamic performance.
