Research on Model of Spherlcal Jolnt Based on Fundamental Characteristic Parameters of Joint Surface

Manufacturing equipment mechanical system consists of a large number of components and joints. The characteristic parameters of joints have influence on the overal performance of manufacturing equipment greatly.Combining with the current research situation and according to the various factors which affect the characteristic parameters of joints,this paper uses its influencing factor research methods that theory is combined with practice and slicing processing to research the characteristic parameters model of mechanical joints.The mathematical models of spherical joints are established based on the basic characteristic parameters of joint surface. The displacement and loading conditions of the joint are also determined and the stiffness matrixes of spherical joints is deduced in the paper. The theoretical foundation is laid for universal parameters and analyzing the performance of mechanical system. Analytic programs of the conical and spherical joints’ characteristics are compiled based on FORTRAN. Its analytic programs and methods are verified to be correct,compared to experiments.
