Abstract: A subway track detecting vehicle, whose trail bogie is equipped with a detector frame is studied in this paper. The hinged detector frame brings a super constraint problem which leads the integration difficulty of the MBS model. The solution is to substitute a flexible body for the rigid detector frame. An equivalent model, in which the bushing force is used as the substitution of the hinge joint, is also obtained. A stiffness value of 3MN/m is recommended to model the bushing force. With the dynamics analysis and the results comparison, the influence of the detector frame, which is totally unsprung mass, on the vehicle’s dynamics behaviour is studied. Besides, the hinge joint of an iron structure can be generally simplified as a bushing force with 3MN/m stiffness and the accuracy of the equivalent model with the bushing force is quite good.
