[0050] S3: data processing of the real-time speed information to obtain a pose state waveform diagram of the object to be detected in the oscillation process, which includes a waveform diagram of the pitch angle information and the roll angle information of the object to be detected in the oscillation process.

[0051] Optionally, the real-time speed information can be data processed to obtain a pose state waveform diagram of the object to be detected in the oscillation process. Specifically, the real-time speed information collected by the measurement unit can be processed and calculated to output the real-time angle change and the oscillation amplitude of the object to be detected.

[0053] In the embodiments of the application, an oscillation magnetic field can be generated by the oscillation generating device to simulate the actual working environment of the object to be detected, and the real-time speed information of the object to be detected can be continuously detected by the measurement unit to obtain the pose state waveform diagram of the object to be detected in the oscillation process, so that people can determine whether the spin center and the center of mass of the permanent magnet are offset and cause vibration, and whether resonance exists between the oscillator and the helmet, and thus the vibration phenomenon and the resonance phenomenon can be eliminated.

[0054] In one possible embodiment, when S2: continuously collecting real-time speed information of the object to be detected in the oscillation process by a measurement unit is performed, the real-time speed information including acceleration information and angular velocity information of the object to be detected, the following steps can be specifically performed:

[0069] Optionally, if the waveform in the pose state waveform diagram oscillates, the center of mass of the oscillation generating device can be adjusted by adjusting the structure of the oscillation generating device until the waveform in the pose state waveform diagram is smooth. At this time, the resonance between the object to be detected and the oscillation generating device is eliminated, thereby avoiding the efficiency reduction phenomenon caused by resonance in the process of driving the object to be detected to oscillate by the oscillation generating device.
