Study on Performance Test Bench of Internal Combustion Rock Drill
Principle and structure of the performance test bench for internal combustion rock drill are introduced. A impact energy absorbing system is designed by using momentum conservation theory, energy conservation theory and damped vibration principle of mass-spring-damping system. The impact energy and frequency is tested by using the magnetic induction speed sensor to measure the vibration velocity of energy absorbing block. Adopting the test bench, many performance index, such as impact energy, impact frequency, drill rod rotation speed and torque, blowing powder capacity can be tested. The test is speedy, reliable and can improve the level of ex-factory examination for rock drill.
