Embodiment Construction

[0062] The technical solutions in the present invention are clearly and completely described below in combination with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0063] Taking the 7-module floating-type low-floor tram formation as an example to illustrate a calculation method for the boundary of a floating-type low-floor tram in the present invention, as figure 1 As shown, the 7-module floating type low-floor tram includes the first bogie module Mc2, the first floating car module F2, the second bogie module T, the second floating car module F3, and the third bogie module connected in sequence from left to right. The bogie module M, th...

Abstract

The invention discloses a floating type low-floor tramcar limit calculation method and system, equipment and a medium. The most unfavorable position characteristic of a vehicle is determined by analyzing the hinging mode between modules, and the limit calculation of the vehicle on a line is divided into the limit calculation on a line straight section and the limit calculation on a line curve section, so that an engineering construction side can carry out construction according to different line conditions; the limit calculation of the straight line section of the line is divided into a vehicle body part and a bogie part, factors considered for the limit calculation of the vehicle body part and the bogie part are different, and the calculation accuracy is improved through the two parts; for the vehicle body part, a calculation model of the X-direction offset of the vehicle body is established by taking a single module and the whole vehicle as research objects, and a calculation model of the Y-direction offset of the vehicle body is established by taking a rigid body module as a research object, so that the calculation model is simpler, and the calculation result is more accurate; and only head and tail end modules and a middle module are calculated for limit calculation of a line curve section, and a calculation model is simplified.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a calculation method, system, equipment and medium for a limit calculation method of a floating type low-floor tram. Background technique [0002] The limit refers to the outline dimension line that is not allowed to be exceeded by the rolling stock and the buildings and equipment close to the line in order to ensure the safety of the rolling stock running on the line and prevent the rolling stock from hitting the buildings and equipment adjacent to the line. Boundary technology is one of the key technologies in various rail vehicle projects such as subway projects / trams, and it is related to the scale, investment and safety of the project after completion. [0003] At present, the domestic subway vehicle margin check generally adopts the CJJ96 subway margin standard based on the full dynamic envelope, which is applicable to conventional four-axle subway vehicles...
