一种船体型线整体优化设计方法研究

摘要

Based on the integration system of numerical optimization, a global optimization method for hull line is explored. The FFD method is used to perform rigid motion of the section plane in longitudinal direction. An optimization example for KCS ship is presented, and the feasibility and availability of this new method is demonstrated.%依托数值优化集成系统，采用曲面参数化基础上的自由变形（FFD）技术，探讨了一种船体曲面整体优化方法。通过适当设定控制点及其变化方式，简易而直截了当地实现了横剖面的刚性纵向移动。以浮心纵向位置构建约束条件，以较少的设计变量，取得较明显的阻力性能收益。对这一方法，进行了概念性的演示和考察，显示其切实可行而且有效。
