摘要
针对在通风网络解算中,若初始值选择不当,Hession矩阵不正定,将导致迭代次数显著增加。为了解决此问题,采用基于信赖域方法的求解大型非线性方程组进行网络解算。应用信赖域方法求得非线性方程组的解,即为网络解算的结果。对基于信赖域方法的矿井通风网络解算进行研究探讨,具有一定的理论指导意义。
In view of the problem that in ventilation network solution, due to inappropriate initial value and indefinite Hession matrix, iterative degree will increase obviously. For this problem, trust region method is introduced to solve large non-linear equations for network solution, and the solution by this method is the result of network solution. Mine ventilation network solution based on trust region method is studied, which has theoretic significance.
