Preliminary study on the magnetohydrodynamic (MHD) angular rate sensor combing coriolis effect at low-frequency
The poor performance of MHD ARS at low frequency has depressed its accuracy and application range. A preliminary study on the magnetohydrodynamic (MHD) angular rate sensor combing Coriolis effect (C-MHD ARS) is made to achieve the low-frequency bandwidth expansion. Physical model of C-MHD ARS is given, and then the physical design with an MHD pump is described. The numerical simulation and experiment are illustrated based on the designed device. The simulation results demonstrate that the Coriolis effect is induced at low frequency and can accelerate the relative velocity. Furthermore, the experiment results confirm the improvement of the C-MHD ARS at low frequency. This study can offer a preliminary understanding of C-MHD ARS design and help us give further error analysis on the sensor.
