2. Vehicle Models By neglecting the inertia eﬀect of the vehicle and considering a vehicle as a moving load or pulsating force, Timoshenko (1922) derived an enormous number of approximate solutions to the problem of simple beams under moving loads. Similar models were adopted by Ayre et al. (1950) and Ayre and Jacobsen (1950) in studying the dynamic responses of a two-span beam, and later by Vellozzi (1967) in studying the vibration of suspension bridges. The moving load model was also adopted by Chen (1978) in analyzing the dynamic response of continuous beams.

Consider a beam simulated by a number of elements traversed by a train, of which each railroad car is idealized as two lumped masses, each supported by a spring-dashpot unit, as shown in Fig. 6.
