摘要
针对载货汽车驾驶室本身,结合其结构特点,从结构传播噪声和空气传播噪声入手,阐述了驾驶室车身噪声性能的评价方法和噪声控制的主要策略,综合采取车身隔振、壁板减振、阻尼控制、隔声处理、吸声处理、密封控制等多种措施进行降噪处理。
Combined with structural features of the truck cab itself, the cab body noise performance evaluation methods and the main noise control strategies are elaborated from structure-borne noise and airborne noise. Body vibration isolation, panel vibration reduction, damping control, sound insulation, sound absorption, sealing control and other measures for noise reduction are adopted.
