Beam subjected to a moving multi-axle systemld not work to satisfaction if used in analysis of motions of all vehicle parts. In any case, the proposed idealization takes care of all the essential effects a multi-axle vehicle is likely to produce in a beam traversed by it. And that is just what we are primarily interested in — beam stresses and deflections.

Infinite beam on elastic foundationney [122]. The motion of a harmonic force was considered by P. M. Mathews [152], that of a sprung mass with two harmonic forces by E. G. Goloskokov and A. P. Filippov [98]. The case of an infinite beam traversed by a force generally variable in time was approximately solved by the author [68].

Introductiontructures, structures composed of those elements and parts, and on elastic media. Moving loads have a great effect on dynamic stresses in such bodies and structures, and cause them to vibrate intensively, especially at high velocities. Their peculiar feature is that they are variable in both time an

Massless beam subjected to a moving loade, i.e. that of the beam mass very small compared to the mass of the moving load. As this primary assumption implies, our computation will have to take account not only of the force effects of the moving load but according to d’Alembert’s principle, of its inertia effects as well.
