摘要
室内道路模拟试验是一项重要汽车试验项目,而标准路面谱的重构是要首先解决的问题之一。在介绍路面功率谱密度理论的基础上,引入了重构路面不平度的核心算法——谐波叠加法,并基于GUI开发了标准路面谱重构软件;最后,对该算法的优缺点进行了分析,并对其未来的发展趋势进行了展望。
Vehicle road simulation test has become a major project of the automobile industry. Reconstruction of road spectrum is one of the problems that should be solved ahead. This paper described the core algorithm--the harmony superposition method based on the theory of PSD and developed the software of standard road spectrum＇s reconstruction on the basis of GUI. Moreover the advantages and disadvantages of this algorithm were analyzed. In the end looking in the future of the development trends of recomstruction.
