摘　　要：为全面、客观地反映防污底系统的减阻、动力和环保性能,研究船舶防污底系统测试与评估方法。利用单转盘扭矩测试方法,计算船舶防污底系统的摩擦转矩系数,测试与评估防污底系统减阻性能;通过计算推力与扭矩系数,测试与评估防污底系统动力性能;采用有机锡化物三维对流扩散方程,确定有机锡化物释放浓度,测试与评估防污底系统环保性能;通过测试与评估防污底系统的减阻、动力和环保性能,全面、客观地反映防污底系统应用效果。实验证明,同进速比下,应用有机硅复合低表面能防污底系统前后,推力与扭矩系数均相差较小,时间延长,有机硅复合低表面能防污底系统的有机锡化物释放浓度逐渐上升,最高浓度在1000μg/m^(3)左右,对海洋环境影响较小,具备较优的环保性能。To comprehensively and objectively reflect the drag reduction,power and environmental performance of anti-fouling bottom systems,research the testing and evaluation methods of ship anti fouling bottom systems.Using the single turntable torque testing method,calculate the friction torque coefficient of the ship's anti-fouling bottom system,and test and evaluate the drag reduction performance of the anti-fouling bottom system;Test and evaluate the dynamic performance of the anti-fouling bottom system by calculating the thrust and torque coefficients;Using the three-dimensional convection diffu-sion equation of organotin compounds,the release concentration of organotin compounds is determined,and the environ-mental performance of the anti-fouling bottom system is tested and evaluated;By testing and evaluating the drag reduction,power,and environmental performance of the anti-fouling bottom system,the application effect of the anti-fouling bottom system can be comprehensively and objectively reflected.Experimental results have shown that under the same speed ratio,there is a small difference in thrust and torque coefficients before and after the application of the organic silicon composite low surface energy anti-fouling bottom system.With prolonged time,the release concentration of organic tin compounds in the organic silicon composite low surface energy anti-fouling bottom system gradually increases,reaching a maximum con-centration of around 1 oo0μg/m^(3),with minimal impact on the marine environment and excellent environmental performance.
