Abstract
Harmonic (frequency response) analysis is often carried out when the input loading is simple harmonic, for instance, when the vehicle is moving on a speed breaker on the road. In the harmonic analysis, the transient vibrations are ignored, resulting in large errors in the calculations of deformations and stresses. In this work, vibration analyses of a vehicle are performed by both harmonic and transient dynamic approaches for the vehicle moving on a speed breaker, which gives a harmonic loading to the vehicle. It is seen that there is a significant difference in the predicted life. This causes large errors in the predicted fatigue life and comfort, especially at the higher excitation frequencies.
