Design of intelligent modeling and calculation software for bi-block ballastless track on bridge

In order to solve the problems of heavy workload of finite element modeling and calculation in the structural design of ballastless track on bridge, lack of unified standards for modeling process and forms of calculation results, and high requirement of professional skills for the designers, the intelligent modeling and calculation software of double-block ballastless track on bridge was developed. This software adopts modular design and provides an integrated man-machine interaction interface, which can automatically complete finite element modeling and calculation, and generate standardized results. This software realizes intelligent data verification and can automatically complete design parameter check and calculation result verification. The accuracy of modeling and calculation results are validated via comparison test, showing that this software has smooth and consistent data processing process and is simple in operation with high efficiency. This software has been successfully applied to the ballastless track design of many high-speed railway engineering projects, which greatly improves the work efficiency and reduces the labor cost of engineering project design.
