L型薄导体电阻的估算方法

本文提出一种利用圆弧导体电阻等效处理不规则导体转角电阻的估算方法。从宽度相等的L型薄导体片的电阻估算出发,推广到宽度不相等的L型导体片电阻估算。通过对估算方法的误差分析,提出细化求解区域来提高估算精度的方法,并结合实际算例对不同的细化程度下估算的精确性加以讨论和比较。

Estimating Method of Resistance of An L-shaped Thin Conductor

In this paper,the method of using arc conductor as an equivalent to estimate corner resistance of irregular shaped conductor is discussed.Starting from studying the estimation of L-shaped thin conductor resistance with constant width,this paper has further extended the method to estimate resistance with variable width.Basing error analysis with the certain method to estimate,an approach of improving the accuracy of estimation by dividing the area to be solved is provided,and several numerical examples are involved to compare the accuracy between estimation with different extent of division.
