Nonstationary random response of a vehicle with a varying structure

International Journal of Vehicle Design (IJVD), Vol. 16, No. 6, 1995

Abstract: This paper presents results from a study of random responses of a vehicle with a reconfiguring flexible structure. The structure is attached to a vehicle supported by a flexible suspension. The vehicle accelerates uniformly on a rough surface generating a nonstationary random excitation. The covariance Liapunov equation for the vehicle and the structure responses is developed. The Liapunov equation is solved for the covariances using fourth order Runge-Kuta integration algorithm. The dynamic interaction between the vehicle and the structure is explored. The effects of damping, surface roughness coefficients, structural configuration, and the vehicle velocities are discussed.
