系统级产品振动试验的探讨与研究

在火箭、导弹、卫星等航天器和坦克装甲车辆等武器装备的研制过程中，系统级产品的鉴定和振动试验的验收具有极其重要的作用。环境振动试验是鉴定结构或仪器设备能否承受预计的振动环境、保证在实际环境下结构的完整性或仪器设备性能、精度不降低的一种必要手段。简要分析了振动试验中的试验技术现状与难点，探讨了振动试验中的谱带谷技术、试验分析手段、力测量与模拟技术(包括力测量设备)，并且提出了改善振动试验有效性的方法和手段。

Investigation on Vibration Testing for System-level Equipments

During the development of spacecrafts such as rockets,missiles and satellites as well as armored vehicles,identification of system-level equipment and performance of vibration testing play very important roles.Environmental vibration testing can check if engineering structure or instrument could endure predicted vibration environtment and assure integrity of structure or high precision and good performance of instrument under real environment.So,it becomes more and more an indispensable means of accomplishing these demands.In the paper,the current development and difficult points in vibration testing technology are briefly analyzed.The band vale technology,the data processing of testing and measurement and the simulation of force(including force measurement instrument)in vibration testing are investigated.The methods and means of improving the effect of vibration testing are also put forward.
