working principle

The system is based on the principle of electromagnetic induction. The digital driving signal generated by the control system is amplified by a power amplifier and output to the dynamic coil inside the vibration table. The moving coil is in a high-intensity magnetic field and generates Lorentz force when powered on, thereby driving the table and the specimen fixed on it to move precisely according to predetermined rules (such as sine and random spectral patterns). The sensor installed on the table feeds back the vibration signal to the control system, forming a closed-loop control to ensure vibration accuracy.
