为计算沥青路面冷铣刨机的旋转多刀铣削阻力
将单把刀具旋转变厚度铣削的任一瞬时近似为等厚度平移切削
平移速度为刀具刀尖点轨迹的切线速度
以剪切破坏建立了单刀铣削阻力计算模型; 将任一时刻各刀具铣削阻力的向量叠加作为该时刻铣削转子的旋转多刀铣削阻力
得到了旋转多刀铣削阻力切向分力的数值计算方法。结合试验数据
以铣削接触面截面积为自变量修正了单刀铣削阻力计算公式
并对比了冷铣刨机试验样机旋转多刀铣削阻力切向分力的实测值与理论计算值
结果表明二者线性相关
相关系数R
2
=0.9; 进而修正了旋转多刀铣削阻力切向分力的计算公式
分析了理论计算值的误差来源。所提出的单刀铣削阻力和多刀铣削阻力计算模型可为旋转类多刀具切削阻力数值计算提供参考。
To calculate the multi-tool milling resistance of asphalt pavement milling machine and transform any instantaneous milling process of rotating single tool into a uniform-thickness translation cutting with the tangential velocity of tool nose
a calculation model of single-tool milling resistance is established based on shear failure. Multi-tool milling resistance is the vector sum of each tool's milling resistance at any given time
and the numerical calculation method of the tangential component force of multi-tool milling resistance is obtained. The calculation formula for single-tool milling resistance is modified with the sectional area of milling contact as the independent variable. The theoretical value and measured data of an experimental prototype milling machine are comp
ared
and the results show that their linear correlation coefficient R
2
is 0.9. The calculation formula for tangential component force of multi-tool milling resistance is modified based on the measured data
and the error source is analyzed. The calculation model may provide a reference for calculation of single- and multi-tool cutting resistances.
