Abstract

Abstract: Firstly， the random discrete characteristics of material particles based on production capacity is discussed， the recursive formula of particle bulk density and expression of interval particle number under the condition of D3 distribution are presented. Secondly， the cutting resistance and the action time pulse load models are established， and put forward to use the ratio of the volume difference of the particle size required by the cutting ball material and the ratio of the volume of a single cut as a correction factor for the pulse load of the whole sphere material， and given the full pulse load model of the sphere material. Finally， the random discrete pulse load model of all the particles is established.

Key words: cutting resistance, bow thick cutting pulse, ball cutting pulse, particle random discretization
