针对一艘600 t级深V型艇的4个线型方案(包括母型和优化船型)进行静水拖曳阻力试验.在对试验结果进行对比分析的基础上,探讨了船首形状改变和球鼻对深V艇阻力及有效功率的影响规律.同时对非线性规划有约束线型优化方法在本艇上的应用效果进行了验证,并确定了一种静水阻力性能良好的深V船型.
Ship model resistance tests were conducted in calm water on four ship models,alternatives of a 600 dwt deep-vee vessel.The models could be classified as a parent and three optimized child forms.Based on analysis of results from the tests,variations from expected effects in resistance and effective horsepower of the deep-vee vessels due to differences in the shape of their bulbous bows were studied.The effectiveness of the shipform optimization method based on wave-making resistance theory combined with constrained nonlinear programming was verified.As a result,a new design for a deep-vee vessel with improved performance was determined.
