Wring tension characteristics of fishing vessel's side power roller
摘要
Abstract
In order to reveal the wringing performance of fishing vessel' s side power roller to the nets and cables,we use XCGTs-I side power roller to test the wring tension of nets with different horizontal hanging ratio,wrapping angle and specifications,and ropes with different diameter.The results show that,when we wring the nets hanging a 215.6 N weight with the horizontal hanging ratio of 0.26,0.50,0.71,the wring tension of side power roller are 173.47 N,163.27 N,and 151.02 N,respectively.When we wring the nets hanging a 215.6 N weight with the same horizontal hanging ratio but different wrapping angle of 150?and 180? the wring tension of side power roller are 173.47 N and 183.67 N.When we wring the same weight with ropes of diameters of 10,16,26 mm,we find that the rope with wide diameter results high wring tension.This study suggest that the variation of net' s horizontal hanging ratio,wrapping angle and rope diameter can influence side power roller's wringing performance.In order to increase the wring tension of side power roller,the distribution of rubber groove of side power roller should be matched with the longitudinal distribution of net knots.关键词
