摘　　要：炮振环境具有典型的重复冲击振动特性,属于严酷振动环境,极易造成附近的设备振动失效。首先对某型航炮射击的振动进行测试并用傅里叶变换分析其振动特性,提出对炮振环境下的设备进行隔振安装设计的方法;然后对炮振环境下的设备进行隔振安装理论分析及有限元仿真;研究结果表明在不改变设备结构的前提下,安装隔振后可使向设备传递的振动降低80%以上,从而极大提高设备的可靠性。研究可为炮振环境下设备的设计提供理论依据。Gunning vibration environment has typical repetitive shock vibration characteristics.It is a harsh vibration environment and can cause vibration failure of nearby equipment very easily.In this paper,the gunning vibration of a type of cannons is tested and the vibration characteristics are analyzed by Fourier transform.The method of vibration isolation installation design for the equipment in the gunning vibration environment is proposed.Then,the corresponding theoretical analysis and finite element simulation are done.The research results show that without the changing of the structure of the equipment,the vibration isolation of the equipment can reduce the vibration transmission from the cannon to the equipment by more than 80%,so that the reliability of the equipment is greatly improved.This research provides a theoretical basis for the design of equipment in the gunning vibration environment.
