摘　　要：针对现有G系列轮式装载机驾驶室内噪声的研究和试验结果,论述降噪型驾驶室结构设计中综合运用隔声、吸声、阻尼减振和隔振等技术,控制驾驶室内噪声的基本思路和具体措施,其中包括:提高驾驶室的密封性能,减少或隔绝中、高频噪声的空气传播途径;驾驶室的蒙皮阻尼减振设计及其内部吸声结构设计;以及驾驶室安装连接处阻尼隔振器的设计。综合实施上述三项措施以后,司机位置处的噪声值稳定在81￣82dB(A)。On the basis of study and test results of Xu Gong Institute on cab noise of G series wheel loaders, the comprehensive application of noise-baffling, noise-absorbing, vibration-damping-and-baffling technologies in noise-reduced cab design are discussed. The basic philosophy and concrete measures to control cab noise include: enhancing the cab sealing, reducing or baffling the middle and high frequency noise transmission in the air, vibration-damping design by lining on the cab walls and noise-absorbing structure design inside the cab, and vibration-damping connection design for the cab mounting. The conclusion is that the noise at driver's position is stabilized at 81~82dB(A) after implementing above measures.
