Embodiment Construction

[0051] See Figure 2 , embodiments of the present invention provides a method of controlling the impact velocity, comprising:

[0052] S21、 Get the target parameter.

[0053] Wherein, the target parameters include environmental parameters and test data under different environmental conditions;

[0054] S22, based on the target parameters, determine the mathematical model of vehicle movement and preset neural network;

[0055] S23, the desired collision point velocity into the trolley motion data model or the preset neural network, to determine the target trolley decoupling position and decoupling point velocity.

[0056] In the present embodiment, first based on the data-driven modeling method, the establishment of a data-based locomotive crash test model and a data-based - physical hybrid model of the locomotive crash test, to determine a reasonable decoupling point and decoupling speed in the crash test, such as Figure 3 as shown. Secondly, artificial intelligence and mac...

Abstract

The invention provides a method, device, storage medium and electronic equipment for controlling impact velocity. The control method first obtains target parameters, wherein the target parameters include environmental parameters and test data under different environmental conditions. Then, based on the target parameters, determine the mathematical model of the vehicle movement and the preset neural network. After that, input the expected collision point speed into the trolley motion data model or preset neural network to determine the target trolley uncoupling position and uncoupling point speed. It can be seen that the impact speed control method provided by the embodiment of the present invention first creates a mathematical model of trolley motion or a preset neural network, and predicts the uncoupling of the trolley and the uncoupling point corresponding to the expected collision point speed through the mathematical model of trolley motion or the preset neural network Velocity, improving the accuracy of collision velocity.

Description

Technical field [0001] The present invention relates to the field of data processing technology, specifically to a control method for impact velocity, apparatus, storage medium and electronic device. Background [0002] Once a rail vehicle collides, it will endanger the personal safety of passengers, so in order to reduce the loss caused by a train collision, it is usually necessary to conduct a real vehicle impact test on the rail vehicle to test the crash resistance of various parts of the rail vehicle in order to improve the rail vehicle and reduce the loss of the rail vehicle collision. [0003] Currently, locomotives are towed in rail vehicle crash tests in the manner of, for example Figure 1 As shown, the drive locomotive and the crash trolley are connected together by a hook and slow device to move forward, when the speed of the two reaches a certain speed, the drive locomotive and the crash trolley are detached, and the crash trolley does a free deceleration movement wi...
