Abstract:The multi-degrees-of-freedom vibration table lacks a convenient and effective method to measure the multi-degrees-of-freedom vibration at present. This article discussed the six degrees of freedom vibration testing method based on the acceleration sensor, and proposed an accelerometer array configuration based on four three-direction accelerometers. The motion state of the configuration is theoretically deduced according to the six degrees of freedom motion system equations, and the specific packaging method is designed. Finally, the encapsulated accelerometer array configuration is verified by the multi degrees of freedom vibration test. The test results show that the proposed accelerometer array configuration based on four three-direction accelerometers can test and restore the angular acceleration. The method is simple and reliable, and can be used for multi degrees of freedom vibration test. It is expected to be widely used in on-site vibration measurement and calibration.
