摘要
根据地铁高架线噪声主要组成及频谱特性,分析了现有单噪声源及传递计算方法的不足,提出了更符合实际工况的双噪声源及传递计算方法。在此基础上利用Cadna A软件将双声源噪声传递计算方法进一步细化为多源分频噪声源及传递仿真计算模型,为地铁高架线噪声分析及控制提供了新思路。
According to the main composition and spectral characteristics of metro elevated line noise,the shortcomings of current calculation method for single noise source and noise transfer are analyzed,a dual noise source and transfer calculation method is presented which is more realistic for practical engineering. On this basis ,the calculation method of dual noise source and noise transfer is further refined into multi-source frequency noise source and transfer simulation model by using the software CadnaA,to provide new ideas of noise analysis and control for metro elevated line.
