摘　　要：为降低高速双体船航行阻力,提高海上救援能力,以某高速双体船为研究对象,设计了一种船尾压浪板,并通过ANSYS Fluent研究了低、中、高速航行时压浪板长度对双体船总阻力的影响规律。利用MATLAB中Polynomial函数拟合航行阻力与速度、压浪板长度之间的关系,采用遗传算法优化压浪板长度。结果表明:压浪板能够有效降低高速双体船航行阻力;减阻效果与压浪板长度有关,且在一定速度范围内有效;压浪板长度为195.40 mm时,减阻效果最好。In order to reduce the sailing resistance of a high-speed catamaran and improve the rescue capability at sea, this paper takes a high-speed catamaran as the research object, designs a stern wave pressure plate and studies the influence law of the length of the wave pressure plate by ANSYS Fluent. The relationship between sailing resistance and speed and wave pressure plate length is fitted by using polynomial function in MATLAB, and the length of wave pressure plate is optimized by using a genetic algorithm. The results show that the wave pressure plate can effectively reduce the sailing resistance of high-speed catamaran, and its drag reduction effect is related to the length of the wave pressure plate, and it is effective in a certain speed range, the length of 195.40 mm has the best drag reduction effect.
