Automobile chassis part calibration method

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.
