IEC 60065 Audio Video Information Test Electric Vibration Test System

 

 

Electric vibration test system DC-2000

 

Product information:

The vibration test system consists of four parts: vibration test bench, power amplifier, controller and cooling fan.

 

1. Vibration test bench

The working principle of the vibrating table:

The energizing conductor is driven by the electromagnetic force in the magnetic field. When the dynamic circle in the magnetic circuit of the electromagnetic vibrating bench passes the alternating current signal, an exciting force is generated in the magnetic circuit.

 

 

 

 

Dynamic circle :

The most important part of the electric vibration table is the dynamic circle, the dynamic circle is an active system. It drives the coil which is placed in the working air gap generated by the magnetic circuit system, to achieve free up and down vibrations by energizing the drive coil.

 

Excitation coil:

The excitation coil of the electric vibrating table is divided into upper excitation and lower excitation. The two together with the dynamic coil form two mutually perpendicular magnetic fields. The coils are cut to each other to generate magnetic induction force when energized, in this way, the vibration bench generates the required exciting force by cutting between the dynamic coil and the excitation.

 

2. Power amplifier

The working principle of the power amplifier: the three-phase AC power is isolated by the power frequency transformer, the buck is sent to the three-phase full-bridge filter, and then the low-ripple DC power supply is sent to the H-bridge transformer through the capacitor filtering, and the output voltage wave passes the normal mode and The common mode choke coil, and is filtered and output to the vibrating table.

 

3. Control part

Our controller uses the world's most advanced DSP framework and control algorithm, 32-bit floating-point 450MHz DSP processor, high-performance 24-bit ADC, up to 130dB dynamic range, ensuring reliable control quality. At the same time, the controller can provide you with the most comprehensive vibration control software module, including: random, sinusoidal, classic shock, resonance search and dwell, shock response spectrum control, sine plus random, sine plus sine, random plus random, long-term waveform Reproduction and other accessibility features. Each function module provides basic and optional functions, and the user can customize the required functions as needed.

 

 

(The above units can be built into the power amplifier box for overall operation or can be placed separately)

 

4. Vertical Expansion Countertop
