KD-9363-EM , Standard Electromagnetic Vibrator

Standard Electromagnetic Vibrator

The purpose of vibration testing is to make a series of controllable vibration simulation in lab, no matter generated by natural or man-made vibration environment; such as waves, tidal flaps, wind, earthquake or rain and so on. It is to test if the product is capable of sustaining the vibration environment exerted from transporting or usage along its effective life cycle; and certify the standard of design & functional requirement of product. The value of vibration testing is to confirm the reliability of products and effectively screen out the bad products in factory; avoiding damages occurred at arrival; and to assess the failure analysis on the non-performing products; expecting to reach a high standard, high-reliability products. The vibration test stresses on the continuity and fatigue; and contributes to the understanding of product’s status under vibration circumstance in a normal environment; and avoids the product’s unpredictable damage caused under certain vibrating frequency for a long time.

The electromagnetic vibrator is associated by the shaker, high power amplifier and multi-functional controller. If conforms to all military, national and commercial vibration testing specifications and is an essential tool for modernized product design, production, QC & QA works. Using it would make your product be the best. The vibration response bandwidth is big and control precision is high; able to simulate all waveforms and specifications; easy to control; good extendibility and easy to maintain.

Electromagnetic Shaker

Coil structure earns Taiwan & USA patents.

Vibrator body is by air-bellow damping design; body’s natural frequency won’t influence floor structure or interfered by external vibration source.

Vibrator is by dual magnetic circuit’s design; the high magnetic alloy and H/APTZ-level coil can generate the best magnetic effort. The body & coil cooling system follows cooling airflow design that can ensure system’s stability.

The overall system is made by gravity casting; beautiful shape and strong; the bottom & side plates are made of spherical graphite cast steel, firm and with a low resonance frequency.

The LASER USB vibrator control system leads the vibration test into a USB 2.0 era. In the vibration controller field it first applies the new generation’s transmission interface. The control software has accepted the opinions from many R&D and production engineers, which makes the LASER USB vibrator control system more close to the four demands that operator concerns most: Convenience, high-performance, flexibility and security.

Can extend to 16 input channels at most.
