The electric vibration test system consists of four parts: vibration test-bed, power amplifier, controller and cooling fan. It is widely used in automobile parts, aerospace, machinery, navigation, communication, electronics, electrician and other industries to detect the structural stability of test samples, which helps to improve the stability of products. Feature: 1. Working principle of shaking table: the electrified conductor moves under the action of electromagnetic force in the magnetic field. When the moving coil in the magnetic circuit of the electromagnetic shaking table passes through the alternating current signal, the exciting force is generated, and the vibration motion is generated in the magnetic circuit. 2. Working principle of power amplifier: the three-phase alternating current is isolated through the power frequency transformer, depressurized and sent to the three-phase full bridge filter, and then the low ripple DC power supply is obtained through capacitor filtering and sent to the H-bridge transformer. The output voltage wave is filtered by the normal mode and common mode choke coil and then output to the shaking table. 3. Venzo series vibration controller, the core product of the controller, is a very excellent controller with high cost performance, which can control all kinds of vibration tables (electric or hydraulic vibration tables, etc.). The most advanced DSP framework and control algorithm in the world, 32-bit floating-point 450MHz DSP processor, high-performance 24 bit ADC and 130dB dynamic range are adopted to ensure reliable control quality.
