摘要
运用多学科设计优化方法,以复摆颚式破碎机为研究对象,将对产品性能具有显著影响的多个相互耦合的学科参数,集成到一个共同的优化平台上进行全局优化,实现设计参数的最佳耦合和产品总体的最优设计。选择破碎机生产能力、动颚行程特性值、机座振动力及动颚质量作为优化设计目标,分别按运动学、动力学和静力学问题建立相应的优化模型;并以ISIGHT软件为集成优化平台,集成ANSYS、MATLAB等软件,通过协同优化数学建模在ISIGHT平台上集成、求解,完成对破碎机的多目标优化设计。优化结果表明,采用多学科优化方法可以实现设计参数的最佳耦合和产品性能的综合优化,优化后的破碎机产品性能得到显著改善。
Taking the compound pendulum jaw crusher as the research object, the paper used multidisciplinary optimization design method, and integrated several intercoupling disciplinary parameters exerting significant influences on product performance into a common optimization platform for global optimization, so as to realize the optimal coupling of design parameters and the optimal overall design of product. The productivity of the crusher, stroke characteristic value of the moving jaw, vibration force of the base and mass of the moving jaw were chosen as the objects of the optimization design, and corresponding optimization models were built respectively according to kinematics, dynamics and static mechanical problems. And then, ISIGHT was taken as the integrated optimization platform to integrate ANSYS and MATLAB etc, and collaborative optimization mathematical modeling was applied to complete integration and solution, so as to achieve multiobject optimization design of the crusher. The optimization results showed the multidisciplinary optimization method could realize the optimal coupling of design parameters and comprehensive optimization of product performance. The performance of the optimized crusher significantly improved.
