摘要
在飞行器的发展史中,减重是一个永恒的主题.本文依据某直升机载雷达的铝合金伺服基座的减重需求,设计了一款与之结构相同的轻量化碳纤维复合材料伺服基座,本文建立了两种材料基座结构的有限元模型,计算对比了两种基座结构的静力学和动力学特点.最后对复合材料基座结构进行了铺层优化设计,进一步减轻了结构质量.本文设计的复合材料基座满足伺服结构的使用要求,并且相对于铝合金结构,质量从2.86kg变为1.48kg,减少了47.9%,减重效果明显.
Abstract
Weight reduction is an eternal topic in the history of aircraft development.Based on the weight reduction requirements of an aluminum alloy servo pedestal for a helicopter-borne radar,this paper proposes a lightweight car-bon fiber composite servo pedestal with the same structure.Finite element models of the pedestals made of both ma-terials are established,and a comparison of the static and dynamic characteristics of the two pedestals is conducted.Finally,ply optimization is carried out for the composite material pedestal to further reduce the pedestal mass.The composite material pedestal proposed in this paper meets the operational requirements of the servo system.Compared to the aluminum alloy pedestal,the mass of the proposed pedestal is reduced from 2.86kg to 1.48kg(47.9%reduc-tion),showing a significant weight reduction effect.
