【摘要】 基于向量回转代数,推导出了向量连续回转的导数与微分的递推计算关系,并阐明了向量微小回转的一些重要性质,从而建立了向量的微回转代数。向量的微回转代数是机构运动分析的有限微回转法的数学基础,作为向量微回转代数的应用、本文对一空间一般7R,7杆机构进行了运动分析。更多还原

【Abstract】 Based on the algebra of rotation, this paper derives the relations between the derivatives of successive rot at ions, bringing to a number of important properties of infinitesimal rotation. The algebra of infinitesimal rotation is the mathematical background of the micro-rotation method,a method for the kinematic analysis of mechanisms. As a concrete example of application cf tbs algebra, the paper also discusses ths kinematic analysis of a general spatial 7R, 7-link mechanism.更多还原
