Package Transportation Vibration Testing Machine 300kgf 25.4mm High Stability
A vibration test machine is a specialized mechanical device used to perform vibration testing on different materials, components, and systems. It works by generating controlled mechanical vibrations that simulate the environmental conditions and operational stresses a product may encounter during normal usage, transportation, and storage.
The system uses a digital power amplifier with sinusoidal pulse width modulation. Its working principle is as follows: using the high-frequency switching capability of the IGBT FET, the low-voltage signal input by the controller is amplified by the digital circuit and restored to the original signal, then output to the moving coil of the vibrating table to drive the electric vibration.
The main components of the intelligent high-voltage power amplifier are the front control unit, power amplifier module, protection circuit, power supply section, and electric cabinet. The system adopts a high-voltage, low-current output form, which reduces power loss during transmission and achieves effective and reasonable impedance matching.
