Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] figure 1 It shows the flow of the method for performing finite element analysis on the vehicle-mounted cabinet in the embodiment. In this embodiment, this method is implemented based on HyperMesh. The method for carrying out finite element analysis on the vehicle-mounted cabinet comprises the following steps:

[0022] S10: In the physical model of the vehicle-mounted cabinet, separate the skeleton and installation devices that are only connected with each other by bolts.

[0023] Vehicle cabinets usually include framework, bolts, mounting hardware and door assemblies. The skeleton plays a supporting role in the vehicle cabinet. Bolts fix the mounting device on the frame. The skeleton is a box-shell structure, usually composed of sheet metal parts. The skeleton includes multiple beams, columns and box panels. Multiple beams and multiple columns are built into a...

Abstract

The present invention relates to a method for carrying out finite element analysis on vehicle-mounted cabinet bodies. The method comprises segmenting a framework and installation elements which are connected with each other through bolts in a physical model of a vehicle-mounted cabinet body; carrying out geometry cleanup and mesh generation on the framework and the installation elements; splicing the framework and the installation elements together to be re-assembled to be the vehicle-mounted cabinet body; and configuring boundary conditions and loads so as to establish a finite element analysis model, and solving the finite element analysis model. Geometry cleanup and mesh generation are carried out on the framework and the installation elements, occupation of computer resources by the step can be greatly reduced, difficulties of technicians in mesh generation within the elements are lowered, and the finite element analysis efficiency of vehicle-mounted cabinet bodies is raised. Meanwhile, because the physical model of the vehicle-mounted cabinet body is disassembled into a plurality of parts, multiple technicians can carry out mesh generation at the same time, thereby shortening time for mesh generation.

Description

technical field [0001] The invention relates to a method for performing finite element analysis on a vehicle-mounted cabinet. Background technique [0002] The on-board cabinet is an important part to realize the normal operation of rail vehicles. At present, the on-board cabinets installed on rail vehicles mainly include: traction on-board cabinets in the field of locomotives, auxiliary on-board cabinets, silicon units, train power supply cabinets, etc.; traction in the field of motor vehicles On-board cabinets, auxiliary on-board cabinets, auxiliary power supply units, chargers, etc.; traction inverters, high-voltage electrical boxes, braking resistors, auxiliary power supplies, extended power supply boxes, auxiliary high-voltage boxes, etc. in the urban rail field. [0003] The reliability of the on-board cabinet directly affects the reliability of the train electronic system, which in turn affects the driving safety. After the model of the vehicle-mounted cabinet is des...
