| 摘 要： | 针对水下航行体出水过程空泡溃灭问题,依据水发射试验装置,设计一套试验方案,研究高速水流冲击弹性边界结构的现象.研究结果表明:高速水流冲击弹性边界时,随着弹性边界工装厚度的增加,压力脉冲脉宽逐渐减小,压力脉冲幅值逐渐增大,其增大部分主要是由于刚度较大产生的高频振荡部分.将数据分析频率窗口降低至500Hz,去掉高频振荡成分...

| Abstract: | This topic is about the experimental study on the question about elastical structure shocked by high speed current.The study is based on the tester for launching water column,and the project is designed.Experiments show that pressure pulse-width decreases gradually with the increase of the width of the elastical structure.Because of strong rigidity of the elastical structure,high-frequency vibration occurs in the elastical structure.So pressure pulse-amplitude increases.After data is processed by means of 5... |
