含运动副间隙的平面函数机构运动点可靠性分析
Point kinematics reliability of planar function mechanisms with joint clearance
摘要
Abstract
Joint clearance is the most important uncertainty to affect on kinematic and dynamic per-formance of mechanisms . To accurately evaluate the kinematic reliability of mechanisms with joint clearance ,the key is to create reasonable and effective probabilistic model of joint clearance . Taking the function generator mechanisms with joint clearance for example ,the structure error and random error were considered to create the motion error function of mechanisms .The Cut Hybrid Dimension Reduction Method was applied to handle the correlation of joint clearance vari-ables and then the equivalent probabilistic model of motion error was established .The First Or-der and Second Moment method was used to solve the point kinematic reliability of the mecha-nisms .The results show that the Cut Hybrid Dimension Reduction Method is validation for sol-ving kinematic reliability of planar function mechanisms with joint clearance when the structure error and random error are considered .关键词
