6-DOF vibration parameters test based on acceleration sensors array

6-DOF vibration parameters test belongs to high-frequency absolute test of multidimensional linear vibration and angular vibration. The devices such as gyroscope are hard to meet the environment of high frequency, and the form of vibration increase the difficulty of untying coupling calculation. A test method based on acceleration sensors array was put forward to be used in fire-new vibration environment to solve the problem, that it is difficult to measure 6-DOF vibration parameters effectively using the technology of GFSINS for reference. It tests the vibration using the complex algorithm by the specific location and direction of sensors. Simultaneously, taking scheme using nine acceleration sensors for an example, it deduced the algorithm of the scheme, and verified the feasibility of the method by model simulation.
