航天产品在运输、发射、在轨运行或返回期间受到的各种瞬态载荷称为冲击载荷。冲击环境可能引起产品结构以及性能损坏甚至失效,因此冲击试验常用于检验和暴露航天产品研制过程中存在的设计问题和加工缺陷。航天实践证明,冲击响应谱试验能够在早期暴露航天产品在材料、结构和工艺等方面的缺陷。为了保证航天器在爆炸冲击环境下的可靠性,有必要进行地面爆炸冲击环境模拟试验以便早期暴露结构缺陷,冲击响应谱试验已经成为大多数航天产品
Various types of transient loads experienced by aerospace products during transport, launch, on-orbit or return are referred to as impact loads. Impact environment may cause product structure and performance damage or even failure, so the impact test is often used to test and expose the space product development process existing design problems and processing defects. Aerospace practice has proved that shock response spectroscopy tests can early expose defects in materials, structures and processes of aerospace products. In order to ensure the reliability of the spacecraft in an explosive environment, it is necessary to simulate the ground blasting impact environment to expose structural defects early. Impact response spectroscopy test has become the most important aerospace product
