Labtone
Medium-force shaker
The EV series of electromagnetic vibration test systems simulate the vibration environment under laboratory conditions, testing various vibration test applications’ shock resistance and reliability. In the laboratory, with the aid of a shaker, sinusoidal, random, and classic shock signals, as well as road patterns, can be performed. The aforementioned laboratory activity is essential for the validation of product quality.
DESCRIPTION
Labtone EV series’ shakers are specifically designed to meet the need for long-time operation. Vertical and horizontal vibrations can be achieved by installing a vibration-resistant basis. The standard platform is equipped with high-efficiency dampers to minimize vibrations to the building. An additional basis is not needed in most cases.
FEATURES
- Robust suspension system and linear motion guiding, strong carrying capacity, high stability
- Load center damper has high static stiffness and low dynamic stiffness, strong carrying capacity, perfect performance on amplitude variation
- High-efficiency power switching provide the finest power consumption and minimize harmonic distortion
- Quick self-diagnosis with safety interlock, high safety reliability
- Airbag shock isolation device for vibration platform without the need for additional foundation, perfect reproduction of vibrational wave, and reduce vibration transmittance
- Provide horizontal and vertical expansion platforms for different application
