摘要
针对传统隔振系统设计方法存在的工作繁杂和难以满足轻量化设计需求的问题,提出一种针对板架式浮筏隔振系统的减重优化方法,基于Abaqus对筏架进行参数化建模和谐响应分析后,设计了对比试验验证有限元方法的准确性。采用拓扑优化方法对筏架的结构进行优化,基于Isight平台和遗传算法对筏架参数进行优化设计。通过有限元软件对优化结果进行动力学分析。结果表明,在隔振系统最终输出加速度和功率流变动1%的情况下,筏架质量减少了37.3%,同时计算时间减少了60%。证明该方法可应用于板架式浮筏隔振系统的减重优化设计中。
In view of the complexity of traditional vibration isolation system design methods and the difficulty in meeting the requirements of lightweight design,an optimization method for weight loss of floating raft isolation system was proposed.After analyzing the harmonious response of the raft by parametric modeling based on Abaqus,a comparative test was designed to verify the accuracy of the finite element method.Topology optimization method is adopted to optimize the structure of the raff,and the parameters of the raft are optimized based on Isight platform and genetic algorithm.The dynamic analysis of the optimized results by finite element software shows that the mass of the raft is reduced by 37.3%and the calculation time is reduced by 60%when the final output acceleration and power flow of the vibration isolation system change by 1%.It is proved that the method can be applied to the weight reduction optimization design of the vibration isolation system of floating raft.
