【摘要】：本研究旨在探索一种简便易行的方法,用于初步判断渔船是否存在"大机小标"现象,且能提前判别新造船螺旋桨轴径的选取是否私下改装从而增加主机功率的可能性。通过研究典型主机改装前后的标定功率、转速和规范对螺旋桨轴径要求的最小值之间的关系,以及螺旋桨轴径的实取裕量与轴系设计手册推荐裕量之间的关系,得出轴径的实际取值的合理性与"大机小标"之间存在一定关联性,从而提出通过测量螺旋桨轴径和实船额定转速初步判断"大机小标"的方法。对现存渔船可以先用此方法筛选,如有必要再进行实船的功率测量,可以大量节省检验成本。对于新造渔船,该方法可在审图阶段作为发现"大机小标"的重要判断指标,控制螺旋桨轴径裕量可以在一定程度上增加违法改装成本,从而减少"大机小标"现象,规范渔机市场,进一步完善渔船规则规范,使得国家的双控政策得以更好地实施。
[Abstract]:For the purpose of this study is to explore a simple, for preliminary judgment whether there is "big machine" phenomenon and can determine in advance of new fishing, shipbuilding propeller shaft diameter selection is modified to increase the likelihood of host private power. Through the study of typical power calibration before and after modification of the host, the relationship between the minimum speed and specification size requirements on the propeller shaft, and the relationship between the diameter of the propeller shaft from the recommended is the margin and the shafting design manual margin, there is a certain correlation between the actual values of the shaft diameter and the rationality of "big machine for small scale", and puts forward the preliminary judgment method of "big small machine" by measuring the propeller the ship shaft diameter and rated speed. This method can be used for screening of existing fishing vessels, ship power measurement and then if necessary, can save a lot of cost for the new test. This method can be used in fishing boats The map stage is found "an important index for judging the big machine for small standard, control the propeller shaft diameter margin can increase the cost of illegal modification to a certain extent, so as to reduce the" big small machine "phenomenon, regulate fishing machine market, to further improve the fishing rules, the double control policy of the country can be better implemented.

【正文快照】： “大机小标”是指柴油机铭牌上标定的额定功率小于柴油机实际额定功率[1],造成渔船主机实际额定功率与对应的渔船功率指标不一致。一般通过柴油机厂的数据造假和渔民对柴油机进行私自改装两种途径使得产品证书的功率远小于实船柴油机功率。“大机小标”一方面降低了船上实际动，
