High Frequency Electrodynamic Shaker Vibration Test Bench

We are a manufacturer of Electrodynamic High Frequency Vibration Shaker series products. Our systems adopt advanced modern technologies including a double-magnetic circuit structure, self-generated skeleton action circles, airborne support, roller bearings and linear guidance, and trunnion isolation. These products can perform X, Y, Z three-axis sinusoidal vibration tests and broadband random vibration tests, as well as classical pulse tests (half-sine, trapezoidal, sawtooth wave) and shock response spectrum tests. They are widely used in national defense, weapons, aviation, aerospace, communications, electronics, electrical appliances, and home appliances industries.

1. Well-designed dynamic circle skeleton, with a higher stage axial resonance frequency.

1. Double magnetic circuit structure ensures high magnetic field intensity and reduces flux leakage. A special degaussing structure can reduce flux leakage to below 1 mT.
2. U-type spring, rollers, and linear bearing provide strong resistance to deflecting load.
3. Air springs are used for vibration isolation. The vibration system works steadily even with heavy load; no special foundation is needed.
4. Protection devices are provided for over-thermal, over-load, over-current, over-voltage, and over-displacement of the vibration tester. Electrical network protection devices cover over-voltage, under-voltage, and lacking phase. Drive power protection includes current-limiting, soft-start, over-temperature, short-current, and module fault protection.
5. Can complete sine, random, and impact environmental tests.
6. This system has low requirements for voltage fluctuation; ≤±10% is acceptable.
7. This system has low requirements for grounding resistance; ≤4Ω is acceptable.
8. High reliability, especially suitable for long-time running.

1. Within a small loading bench, higher acceleration and working frequency are realized, improving the loading capacity and performance of the whole machine bench.
2. Horizontal bench and vibration bench are an integral type, with perfect structure and convenient installation and adjustment.
3. Static pressure track, V-shape, with capacity of slope-resistant and bias-loading resistant. Built-in oil pump, good structure, and easy operation.

VT vertical extended-bench and specified clamps are precision calculated and elaborately designed to ensure the customer acquires the best performance according to perfect structure, high-quality material, and workmanship.
