为了对液压回路或系统进行噪声控制,需要涉及以下几方面的问题:系统的噪声模型;设计、安装和使用方法;减振阻尼、消声和隔声措施的采用等。下面分别讨论这些问题。一、系统的噪声模型控制液压系统的噪声,必须研究向其他元件或空气传输能量的各个不同元件,以探明其自身的噪声发射及彼此之间的相互影响。但由于实际情况是相当复杂的,所以要用精确的数学模型来描述这一控制目前
In order to control the noise of the hydraulic circuit or the system, the following problems need to be addressed: the noise model of the system; the design, installation and use methods; damping damping, the application of noise reduction and noise insulation measures. The following discussion of these issues. System Noise Models To control the noise of a hydraulic system, it is necessary to study the various components that transmit energy to other components or air in order to ascertain their own noise emissions and their mutual influence. However, due to the fact that the situation is rather complicated, accurate mathematical models should be used to describe the current control
