摘要
中型浮动冲击平台海上试验受环境影响因素多、实施难度大,水下爆源爆炸作为中型浮动冲击平台的冲击载荷,试验中对爆源的高精度定位具有重要意义。该文通过对比分析水下爆源定位的各种技术,总结其特点和应用条件,并针对浮动冲击平台水下爆炸试验时爆源受海况影响情况进行研究,设计适用于浮动冲击平台海上试验爆源定位的高精度机械定位方法。计算结果表明该方案简洁、高效,定位精度高,生产布置成本低。该研究结果可为中型浮动冲击平台试验成功实施提供参考,并且也能够适用于其他水下爆炸试验的爆源定位。
The test at sea of medium floating impact platform is affected by many environmental factors and it is difficult to implement. Underwater explosion source explosion is an impact load of a medium floating impact platform. It is of great significance to locate the source accurately. This paper compares and analyzes various techniques applied to underwater explosion source location, summarizes their characteristics and application conditions, and studies the influence of sea conditions on explosion source during underwater explosion test on floating impact platform, and designs a high precision mechanical positioning method for explosion source location in floating impact platform. The calculation results show that the proposed method has high positioning precision and low production layout cost. The results can provide reference for the successful implementation of the medium floating impact platform test, and can also be applied to other underwater explosion tests.
