以烧蚀火炮的阳线磨损曲线和一种挤进压力计算方法为基础，建立了考虑弹带挤进过程的内弹道模型。
Based on the wear curve of lands of erosion guns and a calculation method of engraving pressure, an interior ballistic model with the engraving process is established.
试样磨损量随着载荷的增加而增加，也随着曲线半径的减小而增加；
The wear volume increases accordantly with the vertical load increasing or the curve radius decreasing.
结果表明：轴重与曲线半径是影响钢轨磨损的主要因素。
The results indicate that the axle load and curve radius are two key factors in the wear of rail.
