摘要:
为了获得性能好质量轻的定向管,建立了以质量最小为目标函数,以刚强度要求为约束条件,以复合材料的铺层厚度和缠绕角为优化设计变量的复合材料定向管优化数学模型。应用Py-thon语言实现ABAQUS的二次开发,得到了复合材料定向管的参数化有限元模型。选用多岛遗传算法和序列二次规划法相结合的优化策略,基于iSIGHT优化平台建立了定向管动力学优化求解框架。优化后的复合材料定向管刚强度满足设计要求,质量减小21.9%。
Abstract:
In order to obtain good and light-weight composite materials direction tube,the lightest weight of a direction tube is defined as an objective function,the optimal mathematical model is established by taking the thickness and winding angle of the composite materials layers as design variables and the stiffness and strength as constraints.Secondary development of ABAQUS by using Python language,the parametric finite element model of the composite materials direction tube is obtained.The multi-island genetic algorithm and sequential quadratic programming are used as a combined optimal strategy,the optimization solution frame of the direction tube is established based on iSIGHT optimization platform.Optimization results show that the weight of the composite materials direction tube decreases by 21.9% with the stiffness and strength meeting the design requirements.
