一种提高结构屈曲特征值的优化方法研究

A optimization method research on improved structure buckling eigenvalue

基于渐进结构优化的思想,通过引入屈曲特征值影响系数的概念,提出一种提高结构屈曲特征值的实用优化方法,该方法可以在不改变总质量的前提下提高结构的屈曲特征值,并结合算例验证了该方法的有效性。

Based on the thought of evolutionary structural optimization, through introducing the concept of buckling eigenvalue influence coefficient, this paper put forward a practical optimization method of improving structure buckling eigenvalue, this method could improve structure buckling eigenvalue in the premise of not changing the total quality, and combining with examples demonstrated the efficiency of this method.
