水面舰船耐波性综合评估方法研究

发布时间:2022-11-05 17:04
  当水面舰艇在海上航行时,耐波性是决定作战能力和适用性的最重要的指标之一。舰船的耐波性由许多特性组成:振荡运动,加速度,砰击,甲板掩湿,阻力增加等,它是一个复杂的流体力学问题。因此,在船舶设计的不同阶段,确定可以综合表明具有作战任务的舰船的耐波性能指标是必要的,以用来评估设计出的舰船是否具有所需的良好的耐波性能和作战适用性。 本论文分为四个方面。首先是比较深V船型和圆舭护卫舰。从这些同等排水量(1500吨)的护卫舰的初始稳定性,耐波性性能和阻力来审查它们的优势和劣势。使用MAXSURF软件对这些护卫舰进行船体建模和研究。其次为了确定舯剖面斜升角对船体耐波性和阻力的影响,使用MAXSURF软件设计了五艘具有相同排水量和船长的深V船型护卫舰,舯剖面斜升角角度分别选取了210,230,250,270,29°。从船中到船尾的斜升角取为常数,则船肿斜升角与中横斜升角相等。在第三部分中,选取了具有相同船中斜升角βM=25°和不同中横斜升角βT5°,10°,15°,20°,25°的护卫舰来研究中横斜升角对耐波性和阻力的影响。在第四部分中,在修改现有的母型船基础上设计了两艘具有相同排水量和船长的深...
