An in-vehicle equipment arrangement method and system of a rail vehicle, and related components

Abstract

The invention discloses an in-vehicle equipment arrangement method of a rail vehicle. The in-vehicle equipment arrangement method comprises the following steps of: acquiring a vehicle body parameter of the rail vehicle and determining a vehicle body center according to the vehicle body parameter; obtaining equipment parameters of all in-vehicle equipments, and calculating a vehicle body center ofgravity corresponding to each arrangement mode of placing all in-vehicle equipments on both sides of a vehicle compartment corridor according to the equipment parameters; establishing a linear programmodel according to that center of the vehicle body and the center of gravity of each vehicle body; using a linear programming model to determine the center and center of gravity offset of the vehiclebody corresponding to each arrangement mode, and setting the arrangement mode corresponding to the minimum offset as the preferred arrangement mode so as to arrange all in-vehicle equipment in the rail vehicle according to the preferred arrangement mode. The method can reasonably design the layout scheme of the equipment inside the rail vehicle, and reduce the unbalance rate of the axle load andthe wheel load of the locomotive. The invention also discloses an in-vehicle equipment arrangement system of a rail vehicle and an electronic device, which have the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of rail vehicle weight management and control, in particular to a method and system for arranging equipment in a rail vehicle, and an electronic device. Background technique [0002] Electric locomotives are equipped with various special electrical equipment, mechanical equipment and parts because of the need for concentrated power. The layout method has a great influence on the center of gravity and the imbalance of axle load and wheel load. The weight and center of gravity control of the rolling stock system and components at all levels, the calculation of axle load, wheel load and unbalance rate are the key steps in the design process, and domestic and foreign vehicle development companies attach great importance to it. [0003] In the overall design process of the locomotive in the prior art, in order to balance the axle load of the locomotive and fully exert the traction force, the two-end symmetrical ...

AI Technical Summary

Problems solved by technology

Due to the irregular shape of the equipment and the different weights of the equipment, there is often a large deviation in the symmetrical distribution based on experience, which leads to the fact that the axle load and wheel load deviation cannot be satisfied when the layout plan is reviewed and estimated, so the equipment layout plan must be adjusted, and sometimes even Due to the estimation error, the weighing is not up to standard, which leads to design rework, seriously affects the vehicle production cycle, and causes huge waste of human and material resources

Even if the final layout scheme meets the requirements, it is only a feasible scheme, and it is difficult to reach the optimal distribution point. There is still a large room for optimization in the weight design scheme
