Problems solved by technology

This method does not find the maximum load of the component. The weight may exceed the maximum load of the component when loading, causing plastic deformation of the component. Manually record the load and the corresponding strain value, and then input the data into the Excel table for fitting , no calibration coefficient error analysis was performed, thus affecting the accuracy of the final measured load

Abstract

The invention relates to the technical field of automobile chassis and discloses an automobile chassis part calibration method in order to improve accuracy of automobile chassis part calibration results. The method includes the following steps: collecting wheel center six-component force of an automobile in the process of traveling; decomposing the wheel center six-component force onto each part of an automobile chassis, and acquiring reference load of a to-be-calibrated part; loading input load to the to-be-calibrated part within the range of the reference load in a preset form; collecting the input load and strain value on the to-be-calibrated part according to preset sampling frequency; fitting the input load and the strain value to acquire a coefficient capable of reflecting a changing relationship of the input load and the strain value, wherein the coefficient is a calibration coefficient of the to-be-calibrated part. The automobile chassis part calibration method is used for calibrating automobile chassis parts.

Description

technical field [0001] The invention relates to the technical field of automobile chassis, in particular to a method for calibrating automobile chassis components. Background technique [0002] With the rapid development of the automobile industry, the speed of various models on the market is getting faster and faster. In order to meet the needs of users to the greatest extent, it is necessary to convert the user's driving habits, driving road surface, driving speed, etc. According to the actual load conditions of parts, parts design, virtual simulation analysis, vehicle bench test, system bench test, and parts bench test are carried out according to the actual force of parts, so as to produce more competitive models. [0003] At present, the loads of components are mainly obtained through the following two schemes: [0004] Solution 1: Collect the six-component force data of the whole wheel center, input the collected six-component force data into the Adams suspension virt...
