摘要
浮动冲击平台是考核大中型舰载设备抗冲击能力的重要工具,各海军强国十分重视舰载设备抗冲击考核研究工作。采用小波变换方法对小型浮动平台上的测量信号进行处理分析。分析结果表明:小型浮动冲击平台的冲击响应主要以冲击波作用的高频振动为主,随着振动在结构中的传播,能量逐步衰减;设备缓冲装置能迅速衰减高频振动能量,能有效防护设备高频振动冲击。
Floating shock platform is an important tool in the assessment of equipment＇ s shock resistance abilities of large and medium-sized shipboards. Many navy-powerful countries pay great attention to shipboard＇ s equipment shock test research. Using wavelet analysis method, the measured signal of a small floating platform was processed and analyzed in this paper. The results indicate that the impact response of the small floating platform is mainly high frequency vibration due to shock waves. With the vibration propagating in structures, the energy decays gradually. The equipment＇ s buffer device can rapidly attenuate the energy induced by high frequency vibration, and can effectively protect the equipment from high-frequency vibration impact.
