【摘要】：提出了球面4桿機(jī)構(gòu)5精確點(diǎn)軌跡綜合代數(shù)消元方法.基于球面空間轉(zhuǎn)移矩陣建立了該問題的設(shè)計(jì)方程,使用Groebner基和Sylvester結(jié)式(GS法)相結(jié)合的代數(shù)方法進(jìn)行求解,最終獲得一元高次方程及其全部封閉解析解.通過數(shù)值實(shí)例,并使用Solidworks軟件對(duì)計(jì)算結(jié)果進(jìn)行仿真,結(jié)果表明該方法的正確性.該方法為進(jìn)一步采用代數(shù)法對(duì)其他類型球面機(jī)構(gòu)軌跡綜合問題的研究提供了參考.
[Abstract]:In this paper, a synthetic algebraic elimination method for 5 accurate point locus of spherical four-bar mechanism is proposed. The design equation of the problem is established based on the spherical space transfer matrix and solved by the algebraic method combining Groebner basis and Sylvester resultant GS method. Finally, the univariate higher order equation and all its closed analytic solutions are obtained. The numerical example is used to simulate the results by using Solidworks software. The results show that the method is correct and provides a reference for the further study of trajectory synthesis of other types of spherical mechanisms by algebraic method.
