文摘采用实验手段研究了小型柴油发电机组的噪声源和噪声特性,对不同频率范围的噪声提出了具体可行的隔声罩结构优化措施。针对结构隔声量,分析板结构质量是影响隔声罩隔声量的主要因素,采用拓扑优化方法进行优化设计,使1 000 Hz频率以下噪声隔声量达13.16 d B(A);对隔声罩通风口处的声能泄露,确定中高频噪声为噪声控制主要目标,在考虑管道内存在高次波传播的情况下,分析管道隔板位置和大小对传递损失的影响,采用遗传算法设计和优化通风管道结构,减少高次波的传播,使1 000 Hz^3 500 Hz频率范围内噪声传递损失达30.3 d B(A)。通过以上措施,小型柴油发电机组7 m处的噪声降低至60.7 d B(A)。
