【摘要】 对PEF250×400复摆颚式破碎机动颚的运动轨迹进行分析,以特征点的行程比和偏心轴距为综合优化目标,选取8个设计变量并确定5个方面的约束条件,对动颚运动轨迹进行优化。结果表明,在基本保持破碎机产量的条件下,给、排料口处的行程比明显降低,偏心轴距也得到减小。更多还原

【Abstract】 In this paper,the moving jaw track of PEF250×400 compound swinging type jaw crusher is analyzed and optimized.The optimization objectives are the displacement ratio of characteristic points and shaft eccentricity.Eight design variables are selected and five major constraints are identified for the optimization purpose.The results show that the displacement ratio is markedly improved while the output is maintained and the abrasion of the jaw liner plate is effectively reduced.更多还原
