摘要 通过对某冲焊桥壳的有限元模型进行参数化,经过优化分析,使得桥壳在满足垂直弯曲刚度、垂直弯曲强度和垂直弯曲疲劳寿命的条件下,实现了冲焊桥壳的轻量化设计。优化后的不等厚桥壳结构改变了国内传统的设计方案,为以后的冲焊桥壳设计提供了新的设计思路。 By means of carrying out parameterization on finite element model of certain punching-welding bridge housing and through optimization analysis, this paper realized the light weighted optimization design of punching-welding bridge housing under the conditions of letting the bridge housing to satisfy the demands of perpendicular bending rigidity, the perpendicular bending strength and the perpendicular bending fatigue life. The structure of bridge housing with different thickness after optimization changed the traditional domestic designing scheme, thus provided a new designing train of thought for later design of punching-welding bridge housing.
