安装架结构强度分析与疲劳损伤评估

Structural Strength Analysis and Fatigue Damage Assessment of Mounting Rack

为了保证安装架的结构刚强度以及各设备的可靠性,使其适应载机的过载、冲击、振动等环境条件,采用有限元方法对雷达安装架进行了结构强度分析和随机振动下的疲劳损伤评估。分析结果表明,安装架能够满足结构刚强度要求且不会发生疲劳破坏。同时,该研究结果可以为安装架的优化与减重设计提供重要的理论依据,其结构强度分析和疲劳损伤评估方法可以为今后类似的结构分析提供良好的借鉴与参考。

equipments, In order to ensure the stiffness and strength of the mounting rack as well as the reliabilities of the and accommodating itself to the environmental conditions such as over loading, impact, vibra- tion, etc. , structural strength analysis and fatigue damage by finite element method. Analysis results indicate that the strength assessment under random vibration are carried out mounting rack meets the demands of stiffness and , and no fatigue damage would occur. At the same time, the research result of this paper can provide important theoretical basis for the optimization and weight reduction design of the mounting rack. The methods
