AXIOM

Beam subjected to a moving two-axle system of motion of a two-axle vehicle along a beam was first treated by R. K. Wen [230] whose solution was based on the assumption that the vehicle wheels were continually in contact with the roadway. However, owing to track irregularities the contact between wheels and roadway is easily lost and an impact follows shortly thereafter.*)

Omnipotent

Moving force arbitrarily varying in timeWe shall now turn to the case of a simply supported beam with span . traversed at constant speed . by concentrated force . arbitrarily varying in time. The calculation will also be carried out for several special cases of .(.).

Beam stressesUp to now we have been satisfied with finding the dynamic deflection from its expression in the form of a series. The comparatively fast convergence of the series enabled us to obtain adequately accurate results even with the use of only the first term.

高射炮

Beam subjected to a moving system with two degrees of freedomThe problem in which the moving load mass and the beam mass are both taken into account is far more complicated than the special cases analyzed in Chaps. 1 and 7.
