摘　　要：分析了行星式破岩钻头的优势、破岩机理和钻头刀具运动规律,提出了模型建立的假设条件,建立了行星钻头刀具破岩轨迹的数学模型,推导出刀具轨迹的数学方程。分析研究各参数与轨迹方程的互相关系,提出有利于行星钻头钻进的尺寸参数设计。最后,根据数学模型的轨迹方程推导出了能够保证行星钻头有效破岩钻进的参数条件。Analyzing the advantages of the planetary rock drill bit,the rock breaking mechanism and the motion law of the bit tool,putting forward the model assumptions,establishing the mathematical model of the rock breaking path of the planetary bit tool,and deriving the mathematical equation of the tool path.The relationship between each parameter and trajectory equation was analyzed,and the dimension parameter design for planetary bit drilling was put forward.Finally,the parameter conditions for the effective rock drilling of the planetary bit are deduced according to the mathematical model.
