摘要
磁浮轨检车是用来检测磁浮轨道几何参数,保证磁浮列车安全运行的轮式特种车辆。建立了磁浮轨检车横向振动二自由度模型,研究了在磁浮轨道随机路面激励下横向振动幅值的大小及其对激光三角法测量磁浮轨道几何参数精度的影响,结果表明该影响在所要求的测量精度范围之内。
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.
