Embodiment Construction
[0049] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the application. Obviously, the described embodiment is only It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0050] The inventors of the present application have found through research that a dynamic stress sensor can be installed on the vehicle bogie, and the dynamic stress sensor can detect the dynamic stress of the bogie. Then, the dynamic stress data detected by the dynamic stress sensor can be obtained, and the dynamic stress data can be analyzed to obtain the damage...

The present application discloses a method for determining the bogie coefficient, which can quickly remove invalid data collected in a dynamic sensor, and determine target dynamic stress data for calculating the bogie coefficient according to the first dynamic stress data. The target dynamic stress data is the dynamic stress data corresponding to the first vehicle running on the first intersection. Specifically, first dynamic stress data and intersection data may be acquired, where the first dynamic stress data includes multiple frames of data. Considering the energy of each frame of data in the first dynamic stress data and the zero-crossing rate of the first road crossing, the operating condition of the first vehicle can be reflected. Therefore, according to the road crossing data, and the energy and / or For the zero-crossing rate, target dynamic stress data is determined from the first dynamic stress data. It can be seen that when determining the target dynamic stress data, it is no longer affected by the subjective factors of the analyst, thereby improving the efficiency of determining the target dynamic stress data and correspondingly improving the efficiency of determining the damage of the vehicle bogie.
Description
technical field [0001] The present application relates to the field of vehicles, in particular to a method and device for determining the bogie damage coefficient. Background technique [0002] Vehicle bogies affect the stability of the vehicle in operation. Once the bogie of the vehicle is damaged, it may affect the stability of the vehicle operation and correspondingly affect the riding experience of the passengers. Therefore, it is particularly important to determine the damage condition of the vehicle bogie. [0003] The current solution for determining the damage of the vehicle bogie is inefficient and cannot quickly determine the damage of the vehicle bogie. [0004] Therefore, be badly in need of a kind of scheme, can solve above-mentioned problem. Contents of the invention [0005] The technical problem to be solved in this application is how to improve the efficiency of determining the damage condition of the vehicle bogie, and provide a method and device for d...
