含运动副间隙平面轨迹机构的可靠性设计
Reliability Design of Planar Path Mechanism with Joint Clearance
摘要
Abstract
For planar path mechanism,a novel reliability design method is proposed with dimension tolerance and joint clearance.Considering the mechanism with joint clearance,a hybrid dimension reduction method (HDRM) is adopted to handle the joint clearance variables in kinematic error function.A probabilistic model of per output component error is then established.The joint probability density function of the output components is used to estimate the composite mechanism kinematic reliability.A reliability design model of the planar path mechanisms is established which objective is to minimize the structure error and the kinematic composite reliability is introduced to the constraints.A numerical example is given to illustrate the effectiveness of the proposed method.关键词
