二、YHZS型液压凿岩机冲击器性能参数的测试方法为了揭示活塞的运动规律及油压变化对冲击机构的冲击功、冲击频率等的影响,对冲击器各个性能参数进行实测和分析能为研制YHZS型液压凿岩机提供科学依据。本组的测试工作是采用电阻应变仪测量方法,即用YJD—1型电阻应变仪配合压力传感器测定冲击器前后腔压力变化;用音讯—1甲型音频讯号发生器配合位移传感器测定活塞位移;通过SC—10型示波器录波,拍摄冲击器前后腔油压变化与活塞位移之间的关系曲线,从而得到动力
Second, the YHZS hydraulic rock drill impactor performance parameters of the test method In order to reveal the piston movement and the impact of hydraulic changes on the impact mechanism impact frequency, the impact of the impact of various performance parameters measured and analyzed for the development of YHZS Hydraulic rock drill to provide a scientific basis. This group of tests is the use of resistance strain gauge measurement method, that is, with YJD-1 resistance strain gauge with pressure sensors to measure changes in pressure before and after the impact of the impactor; with audio-1 A-type audio signal generator with the displacement sensor to measure piston displacement; Through the SC-10-type oscilloscope wave recording before and after the impact of the impact of the former hydraulic pressure and piston displacement between the curve to get the power
