Research on the method of simulating road roughness numerically

  • Received Date: 26 Mar 2003

  • 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.
