推土机整机噪声控制及应对措施
Noise Control and Countermeasures of Bulldozers

为了降低推土机整机噪声产生的危害，本文对推土机的主要噪声源的噪声产生机理进行详细分析，然后归纳出动力系统、传动系统、液压系统、机械性、冷却系统五大类噪声源，并对各种类噪声源的源头和传播路径采取相应的措施，使噪声获得有效的控制，从而提升产品的质量和竞争力，为推土机的设计与优化奠定理论基础。
In order to reduce the noise pollution of bulldozers, this paper conducts detailed analysis of the noise mechanism of the bulldozers, and then summarizes four types of noise sources: power system, transmission system, hydraulic system, working device, and cooling system. Corresponding measures are taken for cutting the propagation route and reducing the level of noise, thereby improving product quality and competitiveness, and laying a theoretical foundation for the design and optimization of bulldozers.
