Aiming at the problem of analyzing the influence of railway V-shaped sunroof on the line capacity, a method of simulation analysis is put forward. Firstly, the method clarifies the influence of V-type sunroof on line capacity and discusses the research flow and analysis indexes of capacity impact analysis. On this basis, the data structure design of train operation diagram and V-shaped sunroof is completed. A set of algorithms for calculating impact analysis indicators are designed by using discrete event dynamic system theory and computer simulation technology, including: V-type skylight direct The algorithms that affect the solution of running line set, the solving algorithm of determining the influence area of V-shaped skylight on both sides, and the algorithm of calculating the available capacity of V-shaped skylight on both sides are obtained. In particular, in order to solve the available capacity of V-shaped skylight on both sides of the impact area, the simulation operation flow was designed and the calculation formulas of event deduction, collision judgment, translation amount calculation and event correction in the process were given. Finally, an example is verified.
