| Abstract: | A maglev track inspection vehicle is a kind of special vehicle supported by tires,it measures geometry parameters of maglev track to ensure maglev train runs safely.A lateral vibration model of 2 DOFs of a maglev track inspection vehicle is built here.Its lateral vibration magnitude under the stochastic surface excitation of the maglev track and its effect on the measurement accuracy of the maglev track geometry parameters with the laser triangle method are studied.The result indicates that the effect is within the range of the measurement accuracy required. |
