基于响应面的渔船球鼻艏参数分析及多航速自动优化
Parameter investigation and multi-speed automatic optimization of fishing vessel's bulb bow based on the response surface
摘要
Abstract
The pelagic tuna purse seiner is a medium-high speed fishery vessel. To reduce its wave resis⁃tance, an optimized bulbous bow is usually installed. In order to effectively investigate the bulb bow effect on the wave resistance, a bulb bow transformation method is developed in this paper, through which the bulb bow offsets are transformed into length, breadth, height, and fore-point height parameters and directly used in CFD calculation. The wave resistance is then solved with the Rankine source panel method. Using the method of experimental design, a response surface model of bulb bow parameter effect on wave resis⁃tance is generated. The response surface model indicates that the influences are rather complex, coupled and irregular, and the exact rules differ with speed. Finally, a fast optimization method based on the re⁃sponse surface is applied into the bulb bow optimization, and it is noticed that the optimal solution for the design speed could yield worse resistance performance under service speed, while the multi-speed optimi⁃zation method is more effective for the resistance reduction and energy saving under both design speed and service speed.关键词
