针对舰船舷侧线型优化设计中低阻性能与隐身性能难以协同优化的问题，提出基于“低阻-隐身”协同的舰船舷侧线型优化设计方法。基于薄船理论，将船体对流体的作用视为集中压力，分析舷侧倾斜后兴波形态改变对阻力的影响；考虑雷达波反射路径，设计舷侧倾斜角度，避免因角度过大导致阻力激增。选取舷侧倾斜角度、舷侧表面平整度、舷侧折线数量为核心变量，通过二次多项式回归方法构建响应面模型，获取满足低阻、隐身需求的舷侧线型最优方案。实验结果表明，采用该方法对舰船舷侧线型进行“低阻-隐身”协同工业设计，舰船在全航行过程中阻力稳定低于350 kN；RCS衰减率在35%上下波动，能够实现隐身护卫舰舷侧线型的工程化设计。
Aiming at the problem that it is difficult to optimize the low resistance performance and stealth performance in the optimization design of ship side profile, an optimization design method of ship side profile based on "low resistance stealth" coordination is proposed. Based on the thin ship theory, the effect of the hull on the fluid is regarded as the concentrated pressure, and the influence of the change of wave making shape after the side tilt on the resistance is analyzed; Considering the reflection path of radar wave, the side inclination angle is designed to avoid the surge of resistance due to excessive angle. Taking the side inclination angle, the side surface flatness and the number of side broken lines as the core variables, the response surface model is constructed by quadratic polynomial regression method, and the optimal scheme of the side line type meeting the requirements of low resistance and stealth is obtained. The experimental results show that the “low resistance stealth” collaborative industrial design of the shipboard profile using this method can achieve the engineering design of the shipboard profile of stealth frigates, and the resistance of the ship is stable below 350 kN in the whole navigation process; the RCS attenuation rate fluctuates around 35%.
