Influence of payload on the dynamic stresses in vehicle structures

International Journal of Vehicle Design (IJVD), Vol. 5, No. 4, 1984

Abstract: Payloads contribute to vehicle vibrations not only because of the effect of their masses, but also as a result of the damping and spring stiffness effects they produce (active masses). By applying a suitable transformation, the dynamic stresses in passenger-loaded vehicle structures can be determined without increasing the degree of freedom of the vehicle. Tests have shown that a realistic simulation of pay-load reduces significantly (by 10 to 30%) vehicle stresses (mass forces) in models of elastic structure, when compared to passive simulation.
