| Abstract: | By applying the gtaph theory , a systematic and symbolic method for formulatingthe first-order equations of spatial kinematic chains with multi-loop constraints is presented in thispaper. Based upon topological analysis, two sets of network, namely, linear velocity network andangular velocity network, are defined by using the fundamental circuit and outset respectively.Consequently, a formal and explicit formula of the first-order kinematics is derived. This work canlay a splid foundation for revealing the underlying relationship between the first--order kinematicsand kinetostatics of spatial kinematic chains. |
