Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0024] Such as figure 1 As shown, the traction system of rail vehicles mainly includes input power supply, traction transformer, rectifier, inverter, traction motor and so on. The traction system reduces the voltage of the high-voltage electricity introduced by the roof through the traction transformer, and after the frequency conversion and voltage conversion by the rectifier and inverter, it is sent to the traction motor in a controllable and appropriate manner, and the traction motor drives the vehicle to run.

[0025] Such as figure 2 As shown, the auxiliary design system of rail vehicle traction system is used to assist designers in the design of traction system, mainly including database module, component function model library module, algorithm library module and structural configuration design module.

[0026] The structural configura...

Abstract

The invention relates to an auxiliary design system and design method for a rail vehicle traction system, comprising a database module for storing the electrical capacity and performance parameters of each component of the traction system determined in the design process; a component function model library module for storing and load the steady-state and dynamic models of the main components of the traction system; the structural configuration design module enters the index requirements of vehicle operation in the auxiliary design system, and the auxiliary design system loads the steady-state models of each component of the traction system according to the requirements of the vehicle operating index, and calculates The electrical capacity and performance parameters of each component are stored in the database module, and the designer designs the topology of the traction system according to the electrical capacity and performance parameters of each component. The invention can enable the designer to grasp the steady state and dynamic performance of the designed traction system at any time during the design process, can effectively guide the work of the designer, and enable the designer to design a better scheme.

Description

technical field [0001] The invention relates to an auxiliary design system and a design method, in particular to an auxiliary design system and a design method of a rail vehicle traction system. Background technique [0002] In order to meet the diversified needs of the user market, the design of the traction system of high-speed rail vehicles is required to meet the changes in train performance in time, so the new design scheme needs to consider the steady-state performance and dynamic performance of the system. In the actual design process, it is difficult to know the dynamic performance of the key components of the traction system such as temperature rise and torque ripple in a timely manner, which restricts the designer to propose a better design plan. Contents of the invention [0003] The main purpose of the present invention is to solve the above-mentioned problems and deficiencies, and provide an auxiliary design system for rail vehicle traction systems that can pr...
