【摘要】 应用应力波理论,建立了连续冲击凿岩的理论模型,编制了计算机程序,并且通过实验,对该模型进行了验证。应用此模型可以对凿岩系统的参数一冲击功、冲击频率、转舒速度、转钎扭矩、轴推力和岩石特性等进行选优匹配。更多还原

【Abstract】 A theosetical model for successively percussive rock drilling which was verifiedby the experiment was estabbished and s simulating program about it was compiled by means ofthe Theoty of stress waves .This model can be used to optimize and adjust the parameteres ofdrilling system,such as blow energy,blow frequenties,rotational speeds,torquer,thrusts andcharacteristics of rock etc.更多还原
