Description

Straddle type monorail traffic line optimization method

Technical Field

The patent relates to a straddle type monorail transit line optimization method, which is applied to the optimization design of the straddle type monorail transit line.

Background

The straddle type monorail transit track Liang Jishi is a carrier for running vehicles and is a walking track for running vehicles, and has the characteristics of being quite different from rail transit in which railways and subways walk on steel rails. The requirements of railway and subway lines on the shape of a flat curve and a vertical curve of a track can be realized by adjusting railway ballasts and steel rails, and the requirements on a bridge under the track are mainly met. In the straddle type monorail traffic line, when a vehicle passes through, the top surface and the two side surfaces of the track beam are wheel-rail contact surfaces, namely, the three surfaces bear the load of the vehicle tyre, and the three wheel-rail contact surfaces of the track beam are the tracks for running the vehicle besides bearing the load. Therefore, the line shape of the straddle type monorail traffic is realized by adjusting the line shape of the contact surfaces of the three wheel rails of the track beam, namely, the line shape design of the straddle type monorail traffic is realized by arranging a flat curve (straight line, round curve, mild curve and curve super high) and a vertical curve (round curve) on the track beam.

Through research on the prior patent and publication, the prior linear design of the straddle type monorail traffic line needs to design the size of each rail beam, namely, the line shape is adapted by designing the beam body line shape, and the construction method instruction book is compiled for each rail beam. The construction difficulty is increased and the construction progress is restricted while a large amount of manpower and material resources are consumed. Therefore, the straddle type monorail traffic line needs to be optimally designed.

Disclosure of Invention

The technical problem that this patent will solve is: the optimized line for the track beam with the given beam length and the line shape is finally determined, so that the number of the track beams for line shape design is reduced, the universality of the track beams is increased, the construction progress is accelerated, and emergency replacement of the track beams in future operation is facilitated.
