摘要

摘要: 研究了一种公路路面不平度的数值模拟新方法,该方法直接对给定的公路路面不平度功率谱密度进行研究,经过一系列处理获得路面的不平度值.充分考虑了所关心的汽车固有振动频率和行驶速度影响后,利用该方法对C级公路路面进行数值模拟,模拟结果表明:利用该方法所得路面不平度的功率谱密度与给定的功率谱密度是准确一致的.

Abstract: To obtain exact road roughness, a new method processing directly the given power spectral density was introduced. Considering the effect of the vehicle natural vibration frequency and velocity completely, the simulation and analysis were done on the C grade of road using this method. The results indicate that the power spectral density of the road roughness obtained is the same as the given.
