FEM Study for Van Trailer Dynamic Performance with Air Suspension 2006-01-3521

The road impact load and the vibration are the main factors for the commercial vehicle, especially on the van trailer. In this paper, a new method which puts the operating modal identification and power spectrum density (PSD) analysis together was presented. The analysis results coincided with the road test quite well. The power spectrum response was obtained and the fatigue life of the vehicle was also estimated. This method can be used for the vibration optimization design and a random fatigue design of other commercial vehicles.
