一种圆金属丝铠装材料每千米质量的快速计算方法

A Fast Calculation Method of Per-kilometer Mass of Round Wire Armor Material

圆金属丝铠装材料每千米质量的计算方法有多种,总结了按铠装金属丝根数计算法(方法1),并与《电线电缆手册》计算法(方法2)、节圆计算法(方法3)进行了对比。方法1的计算结果比较准确、但计算参数不易确定;方法2的计算结果负偏差率较大、且仅适用于圆钢丝铠装材料每千米质量的计算,方法3的计算参数容易获得、计算偏差率较小;方法3为从事电缆行业的新员工提供了一种简单、快速计算圆金属丝铠装材料每千米质量的方法。

There are many methods for calculating the per-kilometer mass of round wire armoring materials.The calculation methods were summarized according to the number of armored wires(referred to as Method 1),and compared it with the calculation method in the Handbook of electric wires and cables(referred to as Method 2)and the pitch circle calculation method(referred to as Method 3).Method 1 is the most accurate one,but it requires parameters that are difficult to determine in practical use.Method 2 results in large negative errors and is only applicable when the material is made of steel.Method 3 requires only easily obtainable parameters and results in relatively small errors,Method 3 provides a simple and fast method for new employees engaged in the cable industry to calculate the per-kilometer mass of round wire armoring materials.
