Load file processing method and device of vehicle

Abstract

The invention provides a load file processing method and a load file processing device of a vehicle. The method comprises the steps of setting running control parameters and output control parameters; importing a to-be-processed load file according to the running control parameters; judging whether the running control parameters are matched with attribute parameters of the to-be-processed load file or not; if the running control parameters are judged to be matched with the attribute parameters of the to-be-processed load file, extracting load data according to the running control parameters; processing and exporting the extracted load data. By adopting the method disclosed by the embodiment of the invention, the working efficiency is improved, and the working intensity of workers is reduced; when errors occur, an error report is generated and is automatically modified and processed, so that the subjective fault of the workers is avoided, the working quality is improved, and further excellent quality guarantee is provided for the later-period vehicle performance design.

Description

technical field [0001] The invention relates to the technical fields of vehicles and CAE (Computer Aided Engineering, computer-aided engineering), in particular to a method and device for processing load files of vehicles. Background technique [0002] Among the various performances of vehicles, durability performance is a relatively basic and important index, and it is an important content of vehicle performance design. Among them, CAE simulation analysis is an important part of vehicle durability design, mainly including strength and fatigue life analysis of main components such as body and chassis under specific working conditions, and strength analysis is the most basic and commonly used analysis method. [0003] When performing strength simulation analysis on a certain component of a vehicle, it is usually modeled first using a relatively simple multi-body method to build a single system such as the body and chassis or a vehicle model, and then solve a certain required ...

AI Technical Summary

Problems solved by technology

At present, the process of writing the load table and loading the load into the finite element model after processing is done by manual operation. The main problems are as follows: (1) The data volume of the load file is huge, and the manual operation process is cumbersome, resulting in Low efficiency; (2) manual operation is prone to errors, which affects the design of later vehicle performance
