摘　　要：为了快速、准确地获得高速船型的阻力性能,采用Michell积分法计算某高速巡逻艇的兴波阻力,并将计算结果同线性化的Rankine源法相比较,从而证实了该方法的有效性。同时以Michell积分法为基础,采用非线性规划法进行优化计算,在短时间内能获得性能优良的改良船型,由此可见,Michell积分法对于快速预报高速船型的阻力性能和船型优化是可靠的。In order to obtain the resistance performance of high speed hull forms both rapidly and accurately, the Michell integration method is adopted to compute the wave making resistance of a high speed patrol boat, and the result is compared with linearized Rankine source method to show the validity of the current method. Based on the Michell integration method, the nonlinear programming method is further adopted for optimization computations to obtain an optimized hull form with excellent performance within a short period of time. Therefore, the feasibility of using Michell integration method for fast resistance performance prediction and hull form optimization is demonstrated.
