摘要
文章简要介绍和评估了在随机振动条件下确定结构设计载荷的一些工程方法及其特点,结合国外航天器结构设计的具体实践,推荐几种相对准确和有效的方法,为设计师在初步设计阶段进行结构在随机振动条件下的强度设计提供参考。
In this paper, several engineering methods are introduced and evaluated for determining the quasi static limit load for spacecraft structures under the random vibration conditions. Through comparing their advantages in the practical applications, three relatively accurate and effective methods are recommended for structural strength design under random vibration at preliminary design stage.
