【摘要】 Ω弹簧组作为艉轴密封装置的重要组成部件,其结构补偿能力直接影响艉轴密封装置的密封效果.基于零阶算法,以单片弹簧的特征厚度、宽度、中圆半径和顶圆半径为设计变量,对Ω弹簧组进行多参数优化分析.通过有限元优化设计,分析求解Ω弹簧组各设计参数的响应以及径向刚度的最优解,优化后的刚度值比优化前的增加了11.5%.并对优化前后的Ω弹簧组分别进行谐响应分析,验证了Ω弹簧组径向刚度的优化设计对改变Ω弹簧组频率补偿能力的有效性,进而改善其结构补偿能力.更多还原

【Abstract】 The structural compensation ability of Ω spring set,as an important component of ship seal device,directly affects the sealing effect of ship seal device.Based on zero-order optimization method,multi-parameter optimization of the Ω spring set was conducted with the design variables of the characteristic thickness,width,and the radiuses of both the middle and top circles.The responses of various design parameters and the optimal solution of maximum radial stiffness were analyzed.In conclusion,the radial stiffness increases by 11.5% after the optimization.Moreover,making the harmonic response analysis of Ω spring set before and after the optimization respectively,the results verify the effectiveness of Ω spring stiffness optimization to modify its frequency compensation ability,and thus improve its structural compensation ability.更多还原
