| 摘 要： | 本文针对汽车内部线束网络电磁干扰问题建立了线束网络的电磁模型,并引入了子波分析的方法对该模型的数值求解进行了研究。我们首先构造了针对控制方程的二维正交区间的子波,并将其代入球坐标系下的电磁积分方程,得到了模型数值求解过程所需要的系数矩阵的具体形式。该方法利用子波具有紧支撑和消失矩的特性,能使积分方程数值求解中的满秩矩阵变为稀疏矩阵从而提高求解速度。

| Abstract: | Electromagnetic disturbance by automotive wiring harness is significant for automotive electromagnetic compatibility(EMC).In this work,we establish an automotive wiring harness model and set up some crucial steps needed in solving the model numerically with a wavelet method.First,we construct the wavelets in a two-dimensional orthogonal region which are going to be applied for the solving of wiring harness model.Next,we deduce the formula to calculate the elements of the coefficient matrix for numerical simulation.The results can be used directly in the numerical simulation of automotive EMC. |
