Embodiment

[0065] Embodiment: train driving simulator dynamic control signal database establishment method, such as figure 1 shown, including the following steps:

[0066] S1: Establish the corresponding vehicle dynamics model according to the target model of the train driving simulator and the dynamic parameters of the target model, and collect the vibration signals of the driver's cab under different operating conditions during the dynamics simulation process. The vibration signals include 6 degrees of freedom Displacement, velocity, acceleration. Dynamic parameters include inertial parameters, geometric parameters, suspension parameters, and wheel-rail parameters. The vibration signal is collected by establishing a virtual vibration signal sensor on the floor of the driver's cab.

[0067] Specifically, taking the HXD1 locomotive as an example, the vehicle dynamics model of the HXD1 locomotive is established according to the inertia parameters, wheel-rail parameters, suspension para...

Abstract

The invention discloses a train driving simulator control signal database, an establishment method and a training system. The technical scheme is characterized by comprising the key points of: building a corresponding vehicle dynamic model, and collecting a vibration signal of a driver cab; classifying and counting the target lines according to operation conditions, and formulating a vehicle dynamics simulation matrix and a retrieval strategy; setting a corresponding environment in the vehicle dynamics model according to the vehicle dynamics simulation matrix, and performing dynamics simulation in combination with the vibration signal to obtain a vibration signal file; storing the vibration signal file in a corresponding storage position of a train vibration database; establishing a vibration signal retrieval program and a signal inspection interface; and establishing a calling interface for realizing a motion platform signal calling function. According to the invention, more real andcomprehensive motion platform control information can be provided for a train driving simulator, a more real cab vibration environment is provided for a trained driver, the driver training quality isimproved, and the safe operation of a train is ensured.

Description

technical field [0001] The invention relates to the field of rail transit driving training, more specifically, it relates to a train driving simulator control signal database, an establishment method and a training system. Background technique [0002] In the train driver training system, the advantage of the dynamic simulation simulator is that it can simulate the vibration environment of the driver's cab during the train operation for the trainee driver by controlling the motion platform, providing an immersive training experience of "sound-movement-picture" trinity, Improve the effect of driver training and better ensure the quality and safety of train operation. The train driving dynamic simulation simulator simulates the vibration environment of the driver's cab during the operation of the train by controlling the six-degree-of-freedom motion platform in real time. The motion platform control signal directly determines the dynamic fidelity of the train driving dynamic ...
