凿岩机的应用已有一百二十多年的历史。在此期间,人们致力于其改进,使凿岩机的重量有所减少,频率有所提高。早些时候多用经验的方法来进行改进,近年来随着电子计算机技术的发展,凿岩机的设计已进入到电算模拟化的新阶段。无论用何种方法设计,最终都要用测试来检验其优劣。气动凿岩机是以压缩空气驱动活塞往复运动来工作的。因此,前、后室气压与活塞运动位置的变化(称它为动力过程),对分析凿岩机的工况是至关重要的。凿岩机动力过程与性能参数的测试是进行优化设计必不可少的检 The application of rock drills has a history of more than 120 years. In the meantime, people are committed to their improvement, so that the weight of the rock drill has been reduced and the frequency has increased. Earlier, more experience was used to improve. In recent years, with the development of computer technology, the design of rock drill has entered a new phase of computer simulation. Regardless of the method used, the test must be used to test its merits. Pneumatic rock drills work by reciprocating pistons driven by compressed air. Therefore, changes in the pressure of the front and rear chambers and the position of the piston (called the dynamic process) are crucial to the analysis of the operating conditions of the rock drill. The test of the dynamic process and performance parameters of the rock drill is an essential check for optimal design
