游艇模拟器中阻力建模方法对比研究

Comparative Study on Resistance Modeling Method in Yacht Simulator

为解决游艇模拟器中现有船舶阻力建模方法普适性较差,计算精度不高的问题。对现有高速艇阻力近似建模方法进行分析与总结,将实际游艇模型简化成棱柱形船体,复现查洁法和SIT法并与模型试验数据进行比对,探讨阻力近似建模方法在游艇模拟器中的应用。试验表明简化后的模型与SIT法结合的方法比查洁法适用范围更广泛,求解的阻力与试验值吻合度良好。该方法具有良好的普适性,能解决多种艇型的阻力计算,基本满足游艇模拟器对船舶阻力的仿真需求。

In order to solve the problem that the existing resistance modeling method of yacht has poor universality and the calculation accuracy is not high, approximate resistance modeling methods of high speed craft are analyzed and summarized. The actual yacht model is simplified into a prismatic hull. "ЦАГИ" method and SIT method are reproduced and the simulation results are compared with model test. The application of resistance approximate modeling in the yacht simulator is discussed. The results reveal that the resistance is in good agreement with the experimental value, and the SIT method with simplified hull form is more widely applicable than the "ЦАГИ" method. The SIT method with simplified hull form has good universality, which can be used for resistance calculation of multiple yachts and meet the requirements of the yacht simulator for resistance calculation.
