摘　　要：以某型号压力锅锅盖为研究对象,对金属锅盖进行结构刚强度分析及模态响应分析,根据锅盖的外形特性,装配要求,对金属锅盖进行形貌优化,以增强锅盖的结构刚强度,同时提高锅盖低阶频率。对改进后的金属锅盖进行静态和动态特性分析,结果表明,锅盖的最大垂向变形值由2.55 mm减少至0.76 mm,变形量降低了70%;最大应力由313 MPa减少至176 MPa,降低了44%。证明了优化设计的有效性和可行性,为压力容器及其他金属冲压件的优化设计提供了借鉴和参考。Taking the lid of a certain model of pressure cooker as the research object,the structural stiffness,strength analysis and modal response analysis of the metal lid were carried out.Based on the external characteristics and assem-bly requirements of the lid,the morphology of the metal lid was optimized toenhance its structural stiffness and improve the low-order frequency.Static and dynamic characteristic analyses were carried out on the improved metal lid.The results showed that the maximumvertical deformation value of the lid was reduced from2.55 mmto 0.76 mm,and the deformation was reduced by 70%.The maximumstress was reduced from313 MPa to 176 MPa,a reduction of 44%.The effectiveness and feasibility of the optimized design were proved,which provides a reference and guidance for the optimization design of pressure vessels and other metal stamping components.
