玻璃钢延绳钓船主尺度均衡性探讨

On balance of main dimension of GFRP longliner

为提高玻璃钢延绳钓船设计水平,基于农业部渔船标准化数据库中的钢质延绳钓船样本船,建立回归公式,推导出回归船型的主尺度,与对照组的玻璃钢延绳钓船进行比较,据此提出用于比较延绳钓船设计均衡性的公式。结果表明:在捕鱼工具一致的情况下,尺度较短的船更具有经济性。考虑到玻璃钢的弹性模量偏低,其长度不宜过长。

This paper has built a mathematical regression formula according to the sample steel longliner from Ministry of Agriculture Standardization Database, and derives the main dimensions of the regression ship type. In comparison with the GFRP longliners in the control group, the equations for the comparison of the design balance of longliners are proposed to improve the design level of the GFRP longliners. The results show that the shorter longliners are more economic based on the same fishing tools, especially for GFRP longliners with allowance for the lower elastic modulus of GFRP.
