| Abstract: | Based on the telemetry vibration signal in time domain,a method for design multi-axis random vibration test conditions is presented in this paper.The reference matrix calculated by this method for multi-axis random vibration test is positive-definite.An example is performed in a multi-axis random vibration test by self closed loop control,the result shows that the method presented in this paper is reasonable and feasible. |
