小功率内燃机由于其往复机构的运动,不可避免地产生振动。它危害机器、装置乃至人身健康。本文分析了振动的组成及其对人身的影响,并探讨如何合理规定其允许振级。
Low power internal combustion engines inevitably generate vibrations due to the movement of their reciprocating mechanism. It harms machines, fixtures and even personal health. This paper analyzes the composition of the vibration and its impact on the human body, and discusses how to rationally regulate the allowable vibration level.
