| Abstract: | It is analyzed in this paper that the influences from limb kinematical constraints to degrees of freedom of moving platform in parallel machine design. The concepts of active kinematic chain and driven kinematic chain were deduced. Based on above 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 structure of limbs and joints form are determined immediately. Several practical examples in parallel machine design were given to validate the correctness of design model. |
