Abstract: The present invention discloses a dual meshing method and system for a transformer winding, comprising acquiring the working frequency of a target transformer, and carrying out a first meshing operation on the winding of the target transformer according to the working frequency with the combination of a first meshing strategy; carrying out a second meshing operation on the target transformer winding after the first meshing operation with the combination of a second meshing strategy; and acquiring the mesh size of the target transformer winding after the second meshing operation, and completing meshing on the target transformer according to the mesh size. By reasonably allocating the mesh sizes, the distribution of electromagnetic fields in the transformer winding can be accurately simulated, the consumption of calculation resources can be reduced on the promise of ensuing the accuracy, the simulation efficiency and the accuracy of the simulation result can be improved.

Abstract: A turnout structure includes at least one turnout. The at least one turnout includes: a fixed beam set including a first side beam and a second side beam, and at least two movable beam sets disposed between the first side beam and the second side beam to define at least three switchable traveling pathways. Top surfaces of the at least two movable beam sets are configured to be a first traveling surfaces for traveling wheels of a rail vehicle to travel. Each of the at least two movable beam sets includes a rotating beam and a moving beam. A rotating center is located on a first end of the rotating beam, the rotating beam is configured to rotate around the rotating center, and the moving beam is connected to a second end of the rotating beam and configured to move along a path.

Abstract: A turnout structure, which includes at least one turnout. The at least one turnout includes a fixed beam set. The fixed beam set includes a first side beam and a second side beam. The at least one turnout further includes a movable beam set. The movable beam set is disposed between the first side beam and the second side beam to define two switchable driving channels. A top surface of the movable beam set is configured as a first locomotion surface for locomotion wheels of a railway vehicle. The movable beam set includes a rotating beam and a moving beam. A first end of the rotating beam includes a rotating center. The rotating beam is configured to rotate around the rotating center, and the moving beam is connected to a second end of the rotating beam and configured to move along a path.

Abstract: An inner guide rail switch and a rail transit system having same. The inner guide rail switch includes a fixed beam assembly and a movable beam assembly. Four passageways are defined by the fixed beam assembly. The movable beam assembly includes six movable beams. The four passageways are switched through combined movement of the six movable beams.
