摘要
以典型薄壁圆筒结构为研究对象,运用移动最小二乘法进行撞击能量和撞击载荷拟合,借助MSC.Patran的PCL语言,运用MATLAB软件中自带的优化算法进行优化分析,给出了结构在给定约束条件下的吸能最优结果。针对典型结构耐撞性分析技术的研究,建立了一套可以应用于工程结构耐撞性优化设计的可行方法。
The crashing energy absorption of cylindrical shells was investigated. Genetic algorithm was used to optimize the crashing energy absorption under crashing force restriction. The moving least square approximation technique was used to obtain the crashing energy and crashing force. The optimization results under force fixing was given. The results demonstrate that the method for structural optimization of crashing energy absorption is feasible.
