The invention relates to a joint-
simulation-based on-bridge ballastless turnout
structure system and a dynamic
analysis method thereof. The dynamic
analysis method of the joint-
simulation-based on-bridge ballastless turnout
structure system comprises the following steps of firstly finishing the model establishment of a balastless track and bridge structure by utilizing the ABAQUS
software; secondly finishing the model establishment of a vehicle and a turnout by utilizing the SIMPACK
software; finally establishing rigid-flexible coupled wheel-track contact relationship in the SIMPACK
software to form a vehicle-turnout-bridge
coupling system model, and realizing the connection and the coupled solution of a vehicle model, a turnout model and a bridge model. According to the joint-
simulation-based on-bridge ballastless turnout
structure system and the dynamic
analysis method thereof, which are disclosed by the invention, the complex wheel-track contact relationship of a turnout zone is fully considered, and the model establishment of a turnout and bridge structure is finished according to the actual state to the greatest extent so as to ensure the detailedness, the completion and the accuracy of the model; the model establishment is finished by utilizing the
business software, so that the production, the design and the application are convenient, and the improvement is remarkable by comparing the modeling method provided by the invention with the traditional modeling method.
