摘要
在船舶设计中,恰当地选择船舶的主机功率、最佳的螺旋桨和正确的预报航速,是船舶在航运中船机浆能否达到良好匹配的关键.而这些都取决于船舶的有效功率计算得是否准确.针对在内河中运行的中小型船舶,采用爱尔法作为有效功率计算的原理,利用Matlab/GUIDE编程来进行有效功率计算的研究.并对某实船有效功率的计算,通过与该船船模试验得出的有效功率和用爱尔法手算得出的结果进行对比分析,得到所设计的计算平台可以很好地满足船舶有效功率计算精度的要求,同时极大地提高了工作效率.
In ship design,choosing a right main engine,and a suitable propeller and predicting the ship speed correctly,are the key to matching design of the propeller and engine.All these depend on the calculation of the effective power is correct or not.Aiming at small and mid-sized ship working in the inland river,the Ayer act is used as the calculation principle and based on Matlab/GUIDE to develop the effective power calculation platform.Compared with the effective power result from the given ship model tests and manual calculation,the platform can meet the requirements of calculating the effective power with high precision;meanwhile the working efficiency is highly improved.
