    Abstract
  • To calculate and optimize the resistance performances of unmanned surface vehicle at middle-low speeds, a calculation method of wave-making resistance in running state was proposed in considering nonlinear and viscid effects on the free surface. Based on the linear wave-making resistance theory, the hull form optimization with constrains was converted to a mathematical optimization, by which the functional extremums under specific constrains could be gotten, and the optimal ship form could be calculated by minimizing the objective function under the constrains of specific principle parameters according to the nonlinear layout optimization theory. Theoretic calculation and test results show that the new method is more effective and faster to calculate the wave-making resistance. Optimized hull form has smaller wave-making resistance coefficient in the specific speed range(Froude number is in 0.1-0.7). Compared with the original hull form, the coefficient reduces by about 20% at the optimizing speed(Froude number is 0.5).
