讨论了随机参数服从任意分布时平面连杆机构运动精度可靠性优化设计问题.在已知基本随机参数前四阶矩的情况下,应用随机摄动法和Edgeworth级数方法对平面连杆机构运动精度进行可靠性优化设计,通过计算机程序可以实现随机参数服从任意分布的平面连杆机构的可靠性优化设计,迅速、准确地得到平面连杆机构的结构参数.计算表明,该方法是实用、有效的.
The probabilistic perturbation method and Edgeworth series technique are employed to present a practical and effective optimization design method for kinematics accuracy reliability of the planar linkage machine with arbitrary distribution parameters under the conditions of given the first four moments of basic random variables. Corresponding program can be utilized to obtain reliability optimization design information of planar linkage machine with arbitrary distribution parameters accurately and quickly. And the results demonstrate that the method proposed in this paper is effective and practical.
