摘    要：基于物理规划理论,以偏好设计思想分析和讨论外动颚式破碎机构主要参数与动颚行程特性值的关系,通过构造能反映降低行程特性值的各设计目标的偏好函数,建立物理规划模型,使用遗传算法优化,得到了降低机构磨损的解决方案。通过对偏好设计结果比原始方案及传统颚式破碎机的特性值有较明显的改善。

Abstract: The relationship of main parameters of the mechanism and the characteristic value of stroke is analyzed and discussed with the view of preference design based on the physical programming theory.The preference function of each design objective which shows lowering the characteristic value of stroke is constructed,and the physical programming model is established,and the solution program to reduce structural abrasion is achieved by genetic algorithm.The characteristic value of stroke after the result of preference design is obviously improved with comparison to primitive design and traditional jaw crusher.
