| Abstract: | In this paper ,a natural Coordinate method Suotable for the computer kinematic analysis of multi-kigid body system is introduced. Whenever the natural coordinate is used to describe multibody system, only a few points and unitary vectors are required. The kinematic constraint equation of multibody system comes in two ways,from the rigid-body constraint equations and from constraint equations of joints of kinematic pairs . The constraint equations are linaear or quadratic equations,so it's convenient for sieving process. This method is used for Macpherson Suspension kine matic analysis . The relation of truck change and kingpin inclination change Vs vertical bouncing deflection of wheel is given. |
