Electromagnetic vibration table multi frequency sine vibration test

Electromagnetic vibration table multi frequency sine vibration test

Product Overview
This product is a high-performance electromagnetic vibration testing system designed specifically for precise multi frequency sine vibration testing. It generates precise and controllable vibrations through electromagnetic excitation, simulating the sinusoidal vibration environment that products experience during transportation and use. It is a key equipment for testing product reliability, durability, and structural integrity.

purpose
Mainly used to detect early failures of products, evaluate their structural vibration resistance, fatigue strength, and packaging protection capabilities. By simulating vibrations at preset frequencies and accelerations, design defects and process issues can be effectively identified, providing data support for improving product quality.

Technical Features

1. Precision controlAdopting a fully digital closed-loop control system, ensuring frequency accuracy ≤ 1%, high acceleration control accuracy, and low waveform distortion.

structural design
The equipment adopts an integrated rigid structure, consisting of a platform, excitation coil, dynamic coil, and spring support system. The tabletop is precision machined and standard installation screw holes are reserved for easy installation of specimens. Optimization design of magnetic circuit system, with small magnetic leakage and high efficiency.

Installation and Debugging
After the equipment is delivered, it needs to be placed on a sturdy and flat ground (with a load-bearing capacity of ≥ 1.5 times the weight of the equipment). The user needs to provide a single-phase 220V/50Hz (low thrust) or three-phase 380V/50Hz power supply. We provide professional on-site installation, level calibration, system integration and operation training services to ensure that the equipment is immediately put into normal use.
