Computation of ground vibrations generated by accelerating and braking road vehicles
journal contribution
posted on 2013-01-08, 11:37 authored by Victor V. KrylovThe problem of ground vibration generation by accelerating and braking road
vehicles is considered theoretically for vehicles accelerating (decelerating) with a constant
acceleration a from rest to a constant speed, or braking to a stop from a constant speed.
According to the low-frequency approximation considered, an accelerating or braking
vehicle of mass M is modelled as a point horizontal traction force Fx = aM applied to
the ground and moving along with the vehicle. Frequency spectra of the vertical component
of the ground vibration velocity are investigated as functions of acceleration, final (initial)
speed of the vehicle, ground attenuation, Poisson ratio, and radiation angle Θ relative to
the direction of the vehicle movement. It is shown that, in contrast to vehicles travelling on
uneven roads, the ground vibrations generated by accelerating and braking vehicles are
characterised by directivity patterns V(Θ) which show, in particular, that there is no
radiation in the directions perpendicular to the direction of vehicle movement.
