| With the continuous development of high-speed railway construction, in order to enhance the overall national strength, to formulate China’s high-speed train industry and master the key technology for expanding overseas markets, the Ministry of Science and Technology released technology development plan on railway. At the same time, high-speed railway construction will be in a favorable opportunity of development, for the specialization of high-speed railway construction, inspection and maintenance of high-speed bridges becomes a focus in the course of construction. High-speed railway bridge inspection vehicle provides efficient and safe platform. Therefore, the bridge inspection vehicle’ stability and cameras’selection, in order to ensure the quality of the crack meets the engineering requirements, is crucial.Based on the preliminary design of the bridge inspection vehicle, we utilize SolidWorks to get3D solid modeling, then mesh it through Hypermesh then carry out ANSYS modal analysis on key rotation truss. After all this we treat it with ADAMS, expand the operating process of the kinematic simulation, get the overall center of mass and the key point force, define the operating stability of the most dangerous position, the inspection simulation dates will do goods to the cameras’selection.The main content of this paper is as follows:(1) To build a bridge and the bridge inspection vehicle machine model with Solid Works, after this import the solid model into ADAMS to generate the rigid model, analyze under various load conditions.(2) Using ANSYS to establish a pedestrian truss structure model for modal analysis.(3)Generate rigid bodies to establish the virtual prototype model dynamic simulation and analyze the model under various loads. The frame structure of the dynamic response under various conditions of bridge stress will do goods to see the stability of working status. The core task is to obtain the dynamic center of mass in order to discuss the vehicle’s working stability. |
