摘　　要：浮态控制是一种简单有效的船舶航运节能方式。通过对一艘万车汽车运输船(Pure Car/Truck Carrier,PCTC)进行不同纵倾下的阻力和自航试验,分析纵倾对船舶阻力和推进的影响,以得到不同航速下的最佳纵倾。试验结果显示,高速时最佳纵倾相对于平吃水螺旋桨收到功率减小1%~2%,低速时减小7%~8%。The trim optimization is a simple but effective method for ship energy saving. Resistance and self-propulsion tests are performed for a PCTC model with different trim settings. Influences of the trim on ship resistance and propulsion are analyzed based on the model test results. The optimal trim of the ship at different speeds is obtained. Results show that at high speed, the delivered power for the ship with optimal trim is reduced by 1%-2% compared to the same ship on even keel, and the decrease is 7%-8% when ship at low speed.
