The invention relates to the technical field of cars, in particular to a calibration device and method for a six-dimensional force sensor of a car end relationship test stand. The calibration device for the six-dimensional force sensor of the car end relationship test stand comprises a base, a frame, a test connector, a first force sensor, a vertical driving unit, a second force sensor and a horizontal driving unit, wherein the first force sensor and the second force sensor apply force to the test connector under the drive of the vertical driving unit and the horizontal driving unit, corresponding force is simultaneously applied to the six-dimensional force sensor connected with the test connector, the first force sensor and the second force sensor can measure corresponding pressure values, the six-dimensional force sensor can also obtain a corresponding pressure value, the data measured by the six-dimensional force sensor and the data measured by the first force sensor and the second force sensor are compared and calibrated, and thus the calibration of the six-dimensional force sensor is realized.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a calibration device and a calibration method for a six-dimensional force sensor of a vehicle-end relationship test bench. Background technique [0002] At present, the six-dimensional force (moment) sensor can measure the force and moment in all directions in space. It is a sensor widely used in various test benches. The vehicle-end relationship test bench is the application of this sensor. Due to the frequent use of the vehicle-end relationship test bench, especially when doing fatigue tests, each test requires tens of millions of movements, and the force (moment) test system may have measurement deviations. Therefore, it is necessary to check the vehicle every time it is used. Calibrate the test system of the end-to-end relationship test bench to minimize the impact of measurement deviation on the experimental results. Among them, the six-dimensional force sensor needs to be ...
