Suzhou Dongling Vibration Test Instrument Co., Ltd.

Suzhou Dongling manufactures standard and heavy-duty vibration test equipment designed for structural dynamics and resonance evaluation:

• Electrodynamic Shaker Systems: Air-cooled shakers (thrust up to 70 kN) and water-cooled shakers (thrust ratings up to 600 kN) with peak-to-peak displacements ranging from 51 mm (2 inches) up to 100 mm (4 inches), designed with high first-order armature resonance frequencies.
• ESD Series Modal Exciters: Miniature and compact permanent magnet modal shakers operating across a 5 to 4,000 Hz frequency range, designed for structural modal testing, dynamic stiffness measurement, and resonance analysis in laboratory and aerospace applications.
• Three-Axis Vibration Systems: Simultaneous triaxial vibration test systems providing realistic spatial environmental simulation for complex payload assemblies.
• Fixtures & Expansion Hardware: Finite element-optimized head expanders (magnesium and aluminum alloys), slip tables (convertible, double, and long tables up to 2 meters) with hydrostatic or high-stability low-friction bearings.
• Combined Climatic & Vibration Test Chambers: Integrated test systems coupling electrodynamic shakers with fast-temperature-rate and humidity chambers for thermal cycling and vibration stress screening.
