摘要
针对电缆碳纤维增强复合材料(CFRP)集成构件中电缆埋置位置参数难以确定的问题,建立了集成构件的有限元分析模型和电磁兼容分析模型,提出了一种采用改进响应面法来求解电缆埋置位置参数优化问题的方法。利用该方法,综合考虑电缆的力学性能、电磁兼容性能和制造约束条件,预测得到了一组高质量的电缆埋置位置参数。验证结果表明,使用这组参数得到的集成构件能满足所有的约束条件,所有响应的预测值与实际值的平均误差仅为3%,且埋置电缆对CFRP基体力学性能的影响很小。
Aiming at the problems that were difficult to determine the cable location parameters of cables-carbon fiber reinforced composite(CFRP)integrated components,the finite element analysis model and electromagnetic compatibility analysis model of the integrated components were established.An improved response surface method was proposed and used to solve the optimization problems of cables embedding location parameters.Finally,a set of high-quality cables embedding location parameters were predicted by considering the mechanics properties,EMC performances and manufacturing constraints.The verification results show that the integrated components obtained by using these parameters may meet all the constraints,the average error between the predicted and actual values of all responses is as 3%,and the embedded cables has little effect on the mechanics properties of CFRP matrix.
