| Abstract: | The cross-spectral control, as a key technique in multi-dimensional random vibration tests, is studied in terms of the strategy and algorithm of control, as well as some related techniques. The prototype apparatus and its control principle are discussed. To verify the control effect, a two-dimensional random vibration test is performed. The results show that the control algorithm is correct, and the control strategy gives results in good agreement with the vibration test. |
