建立了简化的某火箭炮有限元模型，将起落架设为设计区域，其他为非设计区域。以减轻质量为目标，设定应力和体积约束，并以典型火箭弹位置建立多工况对起落架进行拓扑优化，得到合理的材料分布情况。以优化结果为参考，修改原有结构，并验证了优化的合理性。

A simplified finite element model of rocket launcher is built. The cradle is taken as design area and other components are as un￣design area. This paper aims at getting the minimum mass and constraining the stress and volume and takens the typical posi￣tions of the rocket launching as the topology optimization of the cradle under the multi￣conditions to find the reasonable material distri￣bution. According to optimization result,its modified structure is reasonble.
