本文根据最小二乘法原理列出索网结构误差平方和的积分算式,然后采用高斯配点法求解双重积分,从而避免了复杂的积分运算。本方法的计算过程简便,精确度高。
In this paper, the integral formula of the square sum of error of the cable net structure is listed according to the principle of least squares. Then the Gaussian collocation method is used to solve the double integral, thus avoiding the complex integral operation. The calculation process of this method is simple and accurate.
