| Abstract: | It is analyzed that the influences from limb kinematical constraints to degrees of freedom of moving platform in the design of parallel machine. The concepts of active kinematic chain and driven kinematic chain were deduced. Based on the analysis a design process is formed. In the design process of parallel machine, as long as the number of freedom of moving platform is given, the configuration of driven kinematic chain, the structures of limbs and joints form are determined immediately. Also a practical example in parallel machine design was given. |
