Static and dynamic characteristics analysis for the gantry framework of bogie parameters determination test bench

As the location and loading device, it was necessary to carry out the stress and modal analysis on the structure scheme of the gantry framework, in order to ensure the test precision of the test bench and avoid the resonance. Through the establishment of dynamic model for the bogie parameters determination dynamic test, the gantry framework loading reaction was determined in this paper, and the stress and modal calculations for solution of the gantry framework was executed by ANSYS Workbench, providing theoretical basis for reasonable design and optimization of the gantry structure.
