Abstract：The test method of the existing swing vehicle was single, which was difficult to meet the requirements of actual working conditions. Based on the 6 degree of freedom platform, the trajectory of its composite motion is used to measure the amplitude of the composite vibration angle through data fusion with the gyroscope sensor. In order to improve the solution accuracy of the wobble vehicle, the linear angular compound vibration was quantified and the amplitude of vibration angle was measured by gyroscope, and the inclination effect of the single acceleration sensor was corrected under the compound vibration, and the expanded uncertainty evaluation was conducted on the reference frequency points after the fusion solution. The results showed that the relative expanded uncertainties of the linear and angular vibrations of the entire testing system after the fusion of the data of the gyroscope and the wobble instrument were 0.36% and 0.08%, respectively, expanding the standard testing conditions of the wobble instrument.
