一、引言 冲击和振动影响着舰船上几乎所有电器设备的使用性能、工作可靠性和预期寿命。因此,一方面要求从电器设备结构设计上采取各种措施,使电器设备具有更高的耐振抗冲性能。另一方面,则需要对电器设备研究更有效的隔振防冲技术,使舰船电器设备免受恶劣的振动冲击干扰。 I. INTRODUCTION Impact and vibration affect the service performance, work reliability and life expectancy of almost all electrical equipment on a ship. Therefore, on the one hand, the structural design of electrical equipment is required to take various measures to make the electrical equipment have a higher vibration and impact resistance. On the other hand, it is necessary to study more effective anti-vibration and anti-shock technology for electrical equipment so as to prevent ship electrical equipment from being disturbed by bad vibration impact.
