Description
A six-degree-of-freedom model of a vehicle was simulated over different hump profiles with a computer program and the results were verified. The resulting vibration characteristics were analyzed to calculate a discomfort index. The discomfort index considered is the equivalent root mean square acceleration specified by the proposal for the revision of ISO 2631. A parametric study was conducted to find the sensitivity of different hump and vehicular parameters on the ride comfort. The optimal hump parameters were obtained for different limiting speeds. Two field humps were simulated and modification of the humps is suggested for optimum performance.
