在论述气动凿岩机振动原理及振动频谱理论计算的基础上,对国内外的手持式和气腿式凿岩机的手柄振动加速度进行了测量分析。在空载和凿岩条件下,对这两类气动凿岩机的振动特性作了研究。 Based on the discussion of the vibration principle and the theoretical calculation of the vibration spectrum of the pneumatic rock driller, the vibration accelerations of the hand-held and air leg rock drills at home and abroad were measured and analyzed. Under no-load and rock drilling conditions, the vibration characteristics of these two types of pneumatic rock drills were studied.
