摘要

针对传统扩张室式压力脉动衰减器低、高频脉动衰减明显的不足，提出了两种改进结构。在衰减器外形尺寸不变的的前提下，以最大化其回冲频率和固有频率处的滤波性能为目标，利用实数编码的标准遗传算法与Pareto排序的遗传算法分别对这两种改进结构进行参数优化，并结合一维平面波理论计算了其插入损失。在运用遗传算法进行优化的过程中，对影响优化的算法主要驱动算子、Pareto最优解、Pareto前沿的选取进行了讨论。结果表明，二维判据空间取得Pareto最优时，得到滤波器的各个结构参数非劣解，优化后的改进型扩张室式压力脉动衰减器在基频及其一次谐频处具有最优的滤波性能。

Abstract

Two improved configurations were put forward, aiming at obvious disadvantage of the traditional expansion chamber hydraulic suppressors that low and high frequency pulsation is attenuated insufficiently. In order to enhance filtering properties at flow ripple frequency and natural frequency under limited space conditions, the insertion loss (IL) on the basis of plane wave theory were calculated by using the real number coding standard genetic algorithm (GAs) and nondominated sorting genetic algorithm (NSGA) to optimize structure parameters. In the process of utilizing genetic algorithms, the main driving operators, Pareto optimal set and Pareto front were discussed. Results showed that when the two-dimensional criterion space got Pareto optimal solutions, several structure parameters' noninferior solutions could be got and the maximum value of IL was optimally obtained at the desired frequencies.
