本文以试验结果为依据,参考国内外资料,综合提出了一个新的凿入力-凿深曲线模型。不仅考虑到了钎头凿入岩石的跃进式破碎特点,而且还引入了钎头与岩石初始间隙的概念,从而能在冲击凿入的电算模拟中,引入不同情况下的凿入边界条件,给模拟程序的应用带来了较大的灵活性。 Based on the test results and referring to the domestic and foreign data, this paper proposes a new model of chisel penetration-sinking curve. It not only considers the characteristics of the leaping crushing of bit sharpened into rock, but also introduces the concept of initial gap between bit and rock so as to be able to introduce the chipping boundary conditions under different conditions into the computer simulation of impact chipping The application of simulation program has brought greater flexibility.
