摘要
根据路面不平度、自相关函数及功率谱密度三者之间的关系,利用时域AR模型模拟了国标GB7031-86规定的各级路面不平度,并且在V isual C++6.0环境下利用跨平台的虚拟现实集成开发包WTK9.0实现了各级路面不平度的可视化。
Based on the relationship of road roughness, its autocorrelation function and its power spectral density, autoregressive （AR） model was employed to simulate road roughness of all grades, which are stipulated by the National Standard GB7031-86. The WorldToolKit （WTK） 9.0, which is an integrated cross-platform development package, was used within the Visual C ＋＋ 6.0 development environment to accomplish the visualization of the road roughness of all grades.
