摘要
为及时确定船体水下清洗时机、消除船体海生物污损带来的不利影响,建立船体污损和洁净2种状态下的航行性能监测数据的模糊匹配方法,消除污损之外其他干扰因素对"轴功率-航速"关系的影响,通过计算同一航速下轴功率增量来评估船体污损程度。利用该方法对某船航行数据进行处理,并与实际情况进行对比,结果表明,基于模糊匹配的污损监测方法可为科学实施船舶水下清洗提供理论和方法依据。
Aimed to ascertain the occasion of hull underwater-cleaning and eliminate the impact caused by hull bio-fouling,a fuzzy matching method is built which is used to match the voyage performance of fouling hull with cleaning hull,the impact on the relationship between shaft power and ship speed caused by interference factors expect the fouling can be eliminated. The degree of fouling can be evaluated by calculating the shaft power increment at the same speed. The voyage data of a ship is calculated by this method,and the calculation result is contrasted with the actual situation of this ship. The results show that the monitoring method about ship fouling based on fuzzy matching is reliable and effective.
