fractal theory takes non-linear complex systems as its objects and is an effective method to solve complex problems 分形理論是以復(fù)雜的非線性系統(tǒng)為研究對象的,是解決復(fù)雜性問題的有效方法。
linear-complex singularity of stewart manipulator is defined on the basis of the conception of linear complex . according to the pitch of instantaneous screw motion in singular configuration, all singularities of stewart mechanism are classified into three different kinds 引入線幾何中線性叢的概念,定義了stewart機(jī)構(gòu)的線性叢奇異,并以奇異時(shí)瞬時(shí)螺旋運(yùn)動(dòng)的節(jié)距將奇異分為三類。
