Yh. Chen et al., Response of an infinite Timoshenko beam on a viscoelastic foundation to a harmonic moving load, J SOUND VIB, 241(5), 2001, pp. 809-824
The dynamic stiffness matrix of an infinite Timoshenko beam on viscoelastic
foundation to a harmonic moving load is established. This dynamic stiffnes
s matrix is essentially a function of the velocity and frequency of the har
monic moving load. The critical velocities and the resonant frequencies can
be easily determined. The dynamic responses of a European high-speed railw
ay subjected to a harmonic moving load are calculated as an example for dem
onstration and discussion. (C) 2001 Academic Press.
