Product Information:

The Electrodynamic Vibration Test System is widely used in aerospace, aviation, military, shipbuilding, automotive, telecommunications, household appliances, electronics, scientific research institutes, and universities. It is designed to simulate vibration conditions encountered during transportation and actual operation in a laboratory environment, verify the environmental adaptability of products, expose potential product defects, and serve as essential testing equipment for new product development, prototype testing, and product qualification testing.This system is a customized reliability environmental testing system capable of performing sinusoidal vibration, random vibration, classical shock, resonance search, and dwell tests. The system consists of four main parts: the vibration shaker, intelligent power amplifier, slip table, and control system.
