摘要
提出了球面4杆机构5精确点轨迹综合代数消元方法.基于球面空间转移矩阵建立了该问题的设计方程,使用Groebner基和Sylvester结式(GS法)相结合的代数方法进行求解,最终获得一元高次方程及其全部封闭解析解.通过数值实例,并使用Solidworks软件对计算结果进行仿真,结果表明该方法的正确性.该方法为进一步采用代数法对其他类型球面机构轨迹综合问题的研究提供了参考.
An algebraic elimination method for five precision points path synthesis of spherical four-bar linkage was presented. Firstly, the kinematic constraint equations of path synthesis were formulated based on the displacement matrix And then, the equations were solved using Groebner-Sylvester （GS） hybrid approach, and a high degree univariate equation and its whole closed-form solutions were accordingly obtained. The results of numerical simulation with Solidworks validate the algorithm, and show that the proposed method can also be used to solve synthesis problems of other kinds of spherical linkages.
