Calibration vehicle for calibrating test bench and calibration method of test bench

Abstract

The invention discloses a calibration vehicle for calibrating a test bench and a calibration method of the test bench. The calibration vehicle comprises a vehicle body, front wheels, rear wheels and a steering wheel; the front wheels are connected with the vehicle body through a front suspension, and the rear wheels are connected with the vehicle body through a rear suspension; the vehicle body, the front suspension, the rear suspension, the front wheels, the rear wheels and the steering wheel are each provided with a monitoring element. According to the calibration vehicle for calibrating the test bench and the calibration method of the test bench, the monitoring element is installed on the calibration vehicle, the calibration vehicle runs on the test bench, and then the sensing data of the test bench sensor is compared with the monitoring data of the monitoring element on the calibration vehicle; the precision state of each test bench sensor of the test bench can be effectively mastered, and all test bench sensors can be monitored at one time, so that the test bench sensors with inaccurate precision can be found out to be corrected or replaced again, the operation is convenient, and the calibration time of the test bench is shortened.

Description

technical field [0001] The present application relates to the technical field of calibration of test benches, in particular to a calibration car used for calibrating test benches and a calibration method of test benches. Background technique [0002] The KC test bench is an important tool for chassis development. There are multiple test bench sensors installed on the test bench to test the chassis system of the vehicle. It can carry out vertical jump conditions, roll conditions, steering conditions, and lateral force conditions. , Longitudinal force working conditions, normalizing moment working conditions and other tests. These working condition monitoring all belong to the content in the prior art, and will not be described in detail here. [0003] Due to the high frequency of use of the KC test bench, the accuracy of the test bench sensor needs to be recalibrated every one to two years to ensure the accuracy of the test. [0004] The traditional calibration method is to...

Problems solved by technology

[0004]The traditional calibration method is to remove the test bench sensor or connect standard sensors in series / parallel, and recalibrate each test bench sensor, which requires a lot of work and takes a long time to calibrate
