The application of vibration and noise reduction in mechanical design
减振降噪在机械设计中的应用

摘要

机械设备在运行过程中会产生一定的噪声问题，包括设备内部零件运行产生的噪声和气动噪声。为了减少机械噪声污染，保护机械周围环境和人员安全，必须将机械运行噪声控制在标准值以内。噪声污染是世界上三大污染之一，同样会影响人们的生活，甚至降低人们身心健康水平。为降低噪声污染，持续提高机械设备发展水平，有必要积极将减振降噪技术融入机械设计中。因此，在机械设备的设计阶段，应采取减振降噪措施，控制噪声源和噪声传播路径，增强机械设计的消声、隔声和吸声功能，提前预防机械振动和气动噪声，在机械设备运行阶段形成良好的振动和噪声控制，强化机械设计的减振降噪效果，确保机械设备投入使用后的安全可靠性。

Abstract

Mechanical equipment will produce certain noise problems during operation, including the noise generated by the operation of internal parts of the equipment and pneumatic noise. In order to reduce mechanical noise pollution, protect the environment around the machinery and personnel safety, it is necessary to control the noise of the machinery operation within the standard value. Noise pollution is one of the three major pollutants in the world, which also affects people's lives and even reduces people's physical and mental health. In order to reduce noise pollution and continuously improve the development level of mechanical equipment, it is necessary to actively integrate vibration and noise reduction technology into mechanical design. Therefore, in the design stage of mechanical equipment, vibration and noise reduction measures should be taken to control noise source and noise propagation path, enhance the noise reduction, sound insulation and sound absorption functions of mechanical design, prevent mechanical vibration and pneumatic noise in advance, form good vibration and noise control in the operation stage of mechanical equipment, and strengthen the vibration and noise reduction effect of mechanical design. Ensure the safety and reliability of mechanical equipment after it is put into use.
