各种工程机械在工作过程中，都要产生振动。这些机械设备，由于自身结构和工作性质，在操作过程中，常需要与人的肢体相接触。当机械与人体接触时，机械的振动将会对人体产生直接的影响。广泛应用于采掘工业、铁路及公路建设的小型气动凿岩机，其工作环境一般是在露天、坑道或 A variety of construction machinery in the work process, have to produce vibration. These mechanical equipment, due to their structure and working nature, often need to be in contact with the human limb during operation. When mechanical contact with the human body, mechanical vibration will have a direct impact on the human body. Widely used in mining industry, rail and road construction of small pneumatic rock drill, the working environment is generally in the open air, tunnel or
