英文摘要The invention claims a mechanical arm error analyzing method on the mechanical arm motion models based on kinematics analysis of each parameter error the mechanical arm the tail end of the position precision of the sensitivity and affecting rule as of mechanical arm is designed and processed when assembling the precision of distributing and it provides basis. Its analysis steps are as follows: By using index area method for establishing of mechanical arm kinematics model; Based on kinematics model establishing mechanical arm the tail end of the position error model; Analyzing each joint error and initial position error of the mechanical arm the tail end of the position precision of the sensitivity; Analysis joint of each error with each articulation angle change of the mechanical arm the tail end of the position precision the effect of the regular; According to the error of the sensitivity and the influence of guide rule of mechanical arm the precision of distributing. The invention has computer accurate the operation is convenient for analyzing and so on completely.
