摘　　要：六面顶压机是中国生产金刚石的主要设备,其关重件铰链梁在工作中承受连续的交变载荷,易出现失效破损。提出RSM和MOGA相结合的方法,对新型六面顶压机的铰链梁进行优化分析。首先建立铰链梁的参数化模型,以关键部分的尺寸为设计参数,以最大应力和最大位移为目标函数,并对其最大质量进行约束;然后使用DOE获得设计试验点;利用RSM获得代理模型;再通过MOGA法搜索全局最优解,最后对铰链梁的优化结果进行评估。结果表明:优化后的铰链梁在质量略微增加的情况下,刚度和强度有效提高,应力集中现象也明显改善。Cubic press is the primary equipment for diamond production in China.Its key component,the hinge beam,bears continuous alternating loads in the working environment and is prone to failure and breakage.In this paper,a method combining response surface method(RSM)and multi-objective genetic algorithms(MOGA)is proposed to optimize the hinge beam of the new hexagon top press.Firstly,the parametric model of the hinge beam is established,with the dimensions of key parts as design parameters,the maximum stress and displacement as objective functions,and the maximum mass is constrained.Then,the optimal space-filling design(OSF)is used as the design of experiments(DOE)to obtain the design experimental points.The proxy model is obtained by the response surface method.Afterward,the global optimum solution is searched using the MOGA method,and the optimal result of the hinge beam is evaluated.The results show that the stiffness and strength of the optimized hinge beam are effectively improved with a slight increase in weight,and the stress concentration is also significantly reduced,providing a useful reference for the design and development of the press.
