Based on the wearcurve of lands of erosion guns and a calculation method of engraving pressure, an interior ballistic model with the engraving process is established.
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。
2
The wear volume increases accordantly with the vertical load increasing or the curve radius decreasing.
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；
3
The results indicate that the axle load and curve radius are two key factors in the wear of rail.
