【Abstract】 A kind of 6 DOF parallel robot used for precision positioning of target and its working characteristics were introduced.Main influencing factors of carrying capacity of target positioned parallel robot have been studied.By adopting the method of combining calculation with CAF,CAE a systematic analysis was carried out on carrying capacity of target positioning parallel robot.An overall consideration was carried out in the course of analysis on each affecting factor,the relationship chart between driving force and load bearing force was presented and the maximum carrying capacity of robot was determined.The analytical method combined mechanics computation with computer simulation,which bears the characteristics of less amount of calculation and strong in operability etc.thus provide a kind of effective method for designing carrying capacity of parallel robot.更多还原
