摘要
根据数理统计理论,分别采用蒙特卡罗法和泰勒级数法求解汽车线束寄生参数的统计特征值——均值和标准偏差,并使用EMC Studio软件计算线束内不同位置的寄生参数值,验证统计性分析的有效性。结果表明:两种方法都能准确、有效地分析汽车线束寄生参数的动态特性,但蒙特卡罗法求解过程简单,计算速度快,结果与泰勒级数法相近,可以有效克服泰勒级数法求解过程复杂,速度慢的缺点。
According to the mathematical statistics, the Monte Carlo method and Taylor series were selected to solve the statistical characteristics of parasitic values which were the mean and standard deviation. The EMC Studio software was used to calculate the parasitic parameter values at different locations in wiring harness to verify the validity of the statistical analysis. The results show that two methods can both analyze the dynamic characteristics of the parasitic parameters accurately and effectively in automotive wiring harness. The Monte Carlo method can quickly obtain the results which are similar to the Taylor series, and it is able to overcome the disadvantage of complex and slow solution process for Taylor series effectively.
