摘　　要：基于运动转换数学模型,将给定两连架杆四组对应角位移的机构综合问题转化为四位置导引机构综合问题。通过构建圆点曲线映射方程建立角度参数与机构解间的一一对应映射关系,确定输出质量特性指标建立稳健性能评价数学模型,计算可行稳健机构解域,并以直观图形式给出可行稳健机构解域上机构的稳健性能及其分布趋势,实现了稳健性能的可视化全解域寻优。Based on the movement conversion model,the synthesis question for given four angle-displacements of rotating links can be converted to the one for given four positions of the coupler. By constructing circle point mapping equations,the one to one relationship between angle parameters and mechanism solutions. The output quality characteristic is determined and the corresponding model to evaluate robustness is established. Feasible robust solution regions can be calculated using this model. Visual graphs given in this paper can reflect robust properties on the feasible robust solution regions and their changing tendencies. The visual optimization problem on the whole solution region for mechanism robust properties can be realized.
