摘　　要：本文提出一种基于有限元分析的人机交互式结构改进设计流程,采取该流程对某航天装置进行改进设计。改进设计前该装置基频84 Hz,给定正弦激励下探针与探孔最大相对位移达到1.57 mm,无法满足设计要求。改进设计后该装置基频达到117 Hz(相比于改进前提高39%),给定正弦激励下探针与探孔最大相对位移仅为0.33 mm(相比于改进前降低79%),满足设计要求。改进后的装置通过了试验考核,验证了该流程的合理性和有效性。In this paper,a human-computer interaction product improvement design method based on finite element analysis was proposed and used in an aerospace assembly.At first,the simulated base frequency result of the aerospace assembly was 84 Hz,and the maximum relative displacement between the probe and the probe hole reached 1.57 mm under the given sinusoidal excitation,which could not satisfy the design requirement.On the contrary,the improved assembly based on the proposed method showed that the simulated base frequency increased 39%from 84 Hz to 117 Hz,the maximum relative displacement between the probe and the probe hole reduced 79%from 1.57 mm to 0.33 mm under the given sinusoidal excitation,which could satisfy the design requirement.The improved assembly passed the experimental assessment,which verified the rationality and effectiveness of the method.
