Problems solved by technology

[0004] However, the traditional motor load model is to attribute the resistance of the vehicle to the load torque of the motor, or use a step function, or directly use a constant, and then equate the wheel speed to the car body speed, without considering the wheel and track Interaction
When this method is used for traction calculation and circuit simulation, it cannot simulate the actual situation of wheel slippage
Therefore, it greatly affects the accuracy of the simulation results

Abstract

The invention relates to a simulation method for traction control of a rail vehicle. The simulation method for traction control of the rail vehicle comprises a wheel speed of the vehicle to change as a first input of the simulation, an adhesion factor of a rail surface to change as a second input of the simulation and an output which is a calculated motor load torque and / or a vehicle speed according to the a vehicle tractive load model, wherein the tractive load model comprises a force transmission model considering an interaction between wheels and rails. The simulation method for traction control of the rail vehicle is suitable for a simulation application of traction control of a motor train unit, a metro and an inter-city train.

Description

Technical field [0001] The invention relates to a simulation method, in particular, to a simulation method suitable for the traction control of a power decentralized rail vehicle. Background technique [0002] In order to complete the rail vehicle design faster and reduce costs, it is necessary to simulate the design of the rail vehicle on the computer before actually manufacturing the prototype car and testing the prototype car, and simulate the actual operating state of the rail vehicle. [0003] The simulation of rail vehicle traction control is an important part of the design and simulation operation of rail vehicle. Among the existing simulation methods, the traction motor load model is the most widely used. It is an important part of traction drive system simulation. It plays an important role in many research related to the transmission system, such as the selection of traction system component parameters and capacity, motor control methods, network voltage fluctuations, a...
