摘要:
研究不作速度分析 ,仅用三心定理无法求解的速度瞬心问题。用射影几何理论阐明有关定式求解的正确性及方法 ,讨论定式的有效性及组合应用的可能性 ;并给出了根据邻接矩阵寻找定式及判别定式有效性的计算机求解方法
Abstract:
This paper studies the method of finding the instant center. T he problem of f inding the instant center can not be solved only by the Aronhold-kennedy theorem w ithout velocity analysis. The correctness of relat ive configurat ions and the method for finding instant centers are ex pounded by projective geometry. The validity of the conf igurat ions and the feasibility to combine them for application are reviewed. T he procedures for finding and dist inguishing valid conf igurat ions based on adjacency matrix for a computer are presented.
