为了降低铲土运输机械的噪声和保护驾驶员的身体健康,对铲土运输机械驾驶室内的噪声产生机理、噪声测试方法以及噪声识别技术进行了分析。在上述分析的基础上提出了驾驶室内降噪措施。铲土运输机械驾驶室的舒适性的提高可以提升国内铲土运输机械的产品竞争力。引言铲土运输机械是进行国家基础建设的主要装备,由于其作业环境的恶劣和复杂,铲土运输机械在作业过程中会伴随噪声的产生,使作业人员的身心健康受到影响。加之,随着人机工程学和工程机械的发
In order to reduce the noise of the shovel transport machinery and protect the health of the driver, the noise generation mechanism, the noise test method and the noise identification technology in the cab of the shovel transport machinery are analyzed. Based on the above analysis, the noise reduction measures in the cab are put forward. Excavation of soil transport machinery to improve the comfort of the cab can enhance the competitiveness of domestic products. Introduction Shovel transport machinery is the main equipment for national infrastructure construction. Due to the harsh and complicated operating environment, the transport machinery with shovel soil is accompanied by noise during operation, which affects the physical and mental health of workers. In addition, with ergonomics and engineering machinery hair
