Vibration shaker for testing the reliability of electronic parts, circuit boards and other small and light specimens
The vibration controller first generates a low-power drive signal, which is balanced and refined through iterative processing. This signal is then sent to the power amplifier, where it is boosted and delivered to the shaker’s drive coil. The amplified signal drives the moving coil, producing the desired vibration motion. An accelerometer continuously monitors the vibration response and sends feedback to the controller, which makes real-time adjustments to keep the output stable and accurate. The process forms a closed-loop control system, ensuring precise vibration performance throughout the test.
