摘　　要：针对气体静压轴承气锤振动现象,实验表征了气锤振动的物理本质。运用单自由度系统振动模型,研究气体静压轴承的气锤振动现象,揭示了轴承设计参数与气锤振动之间的规律性,并与实验研究结果进行对比,发现两者具有很好的一致性,从而验证了理论模型的可行性。并进一步阐述了气锤振动的成因过程,为气体静压轴承气锤振动的研究提供一种新的思路,具有一定的理论研究价值。As to the vibrating phenomenon of the pneumatic hammer in aerostatic bearings, a vibrant model of one - single freedom system was established to study the pneumatic hammer from the point of sympathetic vibration. Meanwhile, theoretic re- sults were compared with experiment~ resutts of pneumatic hammer and their error was ana/yzed in order to validate feasibility of theory$ model. According to experiment~ results, it brought forward one of methods to modify the pneumatic hammer model~ pa- rameters. It can offer a new path to study the pneumatic hammer and have some academic value.
