活塞式鱼雷凸轮发动机配气参数优化研究

Research on the optimization of the piston cam torpedo engine's gas distribution parameter

为了对活塞式鱼雷凸轮发动机配气参数进行优化,选择有效燃烧消耗率作为目标函数,运用遗传算法,得出鱼雷在基准航深时的最佳配气参数值,并与发动机原型配气参数进行对比,结果表明,该优化方法是可行的。

In order to optimize the gas distribution parameter of the piston cam torpedo engine, the effective burning consumption rate is chosen as the objective function at first, and then the optimal gas distribution parameter is gained by using genetic algorithms when torpedo is in the reference running depth. The result is compared with the gas distribution parameter of the prototype engine finally. It is concluded that this optimization method is feasible.
