摘要：In this study, a method to extract bridge vibration
components from vehicle vibration data is proposed. The aim of
this technology is to accurately estimate the bridge position, to
improve the accuracy of on-going monitoring. The technology
of on-going monitoring is a kind of alternate inspection for
bridges’ status by using only data measured on a traveling
vehicle. The estimation process mainly consists of three steps; 1)
measuring the acceleration vibrations on the unsprung-mass
points at the front and rear axes, 2) synchronizing positions of
the measured data, and 3) calculating the subtraction of the two
synchronized data. The applicability of this method is
numerically examined, in which the RBSM and FEM are used
to simulate VBI (Vehicle-Bridge Interaction) system. This
numerical experiment shows that the proposed method can
accurately estimate the bridge position.
