摘　　要：捻制系数是钢丝绳设计中的一个重要参量,根据拉格朗日中值定理,求出捻制系数3位精确数字的近似计算公式。与已知的捻制系数对比,采用近似计算公式的最大误差为9×10^(-3),由此得出可以达到工程应用的捻制系数计算方法。并用两个实例说明手工计算方法。Spinning factor is an important parameter in design of ropes.According to Lagrange mean value theorem,approximate formula for calculating spinning factor with three significant digits is derived.By comparing with known data of spinning factor,the maximum error of approximate formula is 9×10^(-3),and thus a method for calculating spinning factor that can meet engineering application requirements is obtained.Two examples are given to illustrate manual calculation method.
