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。
The vibration characters of both types of rock drifters under noload and drifting operations are studied.
通过测量凿岩机工作时的振动频率、钎杆转速、气温、气压和耗气量等性能参数，自动生成测试报告。
By testing vibration frequency, moving speed of drill rod, atmospheric temperature, pressure and consumption, a test report is automatically worked out.
