功率谱密度是描述振动信号的最重要的方式。本文针对产品公路运输试验中的振动响应信号分析需求，通过对比多种经典功率谱估计算法和现代谱估计算法，以及相同算法在不同参数选择上的异同，推荐采用现代功率谱估计的Burg算法。本文的对比分析可为实测运输振动信号处理提供参考。

Power Spectrum Density (PSD) is one of the most important ways to represent the vibration signals. This paper meets the need of vibration response signal analysis in road transporting test. Several classic and modern PSD estimation methods and their parameters are compared, and the modern PSD estimation method with Burg algorithm is recommended. The comparisons in this paper provide the reference for measuring transportation vibration signals.
