The invention aims to provide a transportation work calculation method suitable for a tug. The transportation work calculation method comprises the following steps: calibrating the jacking force of the tug by adopting a tie column towing force test method; the actual transportation work of the tug is calculated by utilizing the collected navigational speed, the propeller rotating speed and the rudder angle of the tug and adopting a numerical integration method. According to the method, the operation characteristics of a specific type of ship of the tug are considered, the parameter of the jacking force of the tug is adopted to replace the total ton and the load ton of a conventional ship, the total ton and the load ton are multiplied by the navigational speed, integration is carried out, the transportation work of the tug is obtained through calculation, and the operation capacity of the tug can be accurately and effectively described; according to the method, the effective towing force of the tug is calibrated by adopting a tie column towing force test method, and then the effective jacking force of the tug is calculated by adopting the rotating speed of a propeller and a rudder angle.

    本发明的目的在于提供一种适用于拖轮的运输功计算方法,包括如下步骤:采用系柱拖力试验的方法对拖轮的顶推力进行标定;利用采集得到的拖轮航速、螺旋桨转速、舵角,采用数值积分的方法,计算拖轮实际运输功。本发明考虑拖轮这一特定类型船舶的营运特征,提出采用拖轮顶推力这一参数替代常规船舶的总吨和载重吨,与航速相乘并进行积分,从而计算得到拖轮的运输功,能够准确有效的描述拖轮的营运能力;本发明提出采用系柱拖力试验的方法对拖轮有效拖力进行标定,进而采用螺旋桨转速和舵角计算得到拖轮有效顶推力。
