Electrodynamic Vibration Shaker 300kgf 2-2500Hz High Frequency Vibration Tester
Electrodynamic Vibration Mechanical Shaker — a high-frequency vibration tester engineered for precision sinusoidal, random, and shock testing across X, Y, and Z axes. Built with a double-magnetic circuit structure and advanced dynamic circle skeleton, this system delivers reliable performance for demanding laboratory, research, and industrial applications.
- Well-designed dynamic circle skeleton with a higher stage axial resonance frequency.
- Two-magnetic circuit design ensures low magnetic flux leakage, compact structure, and rational layout.
- Rocker rod roller bearings with import-oriented composite body stiffness orientation for superior eccentric load capacity.
- Trunnion isolation foundation dedicated to hormone use, with convenient mobile installation.
- Advanced technology move-around system ensures high reliability of the dynamic circle.
- New duct design enhances the cooling effect.
- Static stiffness and dynamic stiffness of the bearing balloon are minimized, raising the vibration table bearing capacity and improving low-frequency performance.
