Test principle:
The movement of the current-carrying conductor in the magnetic field is caused by the action of the electromagnetic force. When the moving coil in the magnetic circuit of the electromagnetic vibrating table passes through the alternating current signal, an exciting force is generated to generate vibration in the magnetic circuit.
Vibration table construction:
Digital vibration controller:
(1) Introduction to digital vibration controller:
The vibration controller is of advanced distribution structure system, and closed-loop control is achieved by DSP processor. PC is independent of control loop to ensure real-time and high efficiency of the control system so as to timely and rapidly respond to any changes of the test system, and ensure control stability and high precision.
32-bit floating-point DSP processor with primary frequency up to 300MHz and 24-bit resolution ADC/DAC are used for hardware in coordination with high precision floating-point digital filtering and low noise design technology of hardware circuit. The dynamic random control range of the controller is more than 90dB and the signal to noise ratio is more than 100dB.
