摘要
为验证J.Halling的圆柱在平面上滚动的阻力公式计算气囊滚动阻力系数的合理性,通过对比分析气囊搬运圆筒过程的阻力测试结果与理论计算值,结果表明:运用J.Halling滚动阻力公式计算的气囊滚动阻力系数能满足实际施工需要。
To validate the calculated value of the rolling resistance coefficient of air-bags using J. Hailing resistance formula for the cylindrical roller rolling on the plane, the results of calculation and tests of the roiling resistance for transporting cylin- der by air-bags are compared and analyzed, which showed that the calculated value of the air-bags Rolling Resistance Coef- ficient using J.Halling formula can meet the practical construction process.
