Air Cooled Vibration Test System 4000kgf -7000kgf

Labtone EV series of electrodynamic shaker vibration test System simulate the vibration environment under the laboratory condition, and test the impact strength as well as reliability of various vibration test applications.  

It simulate the vibration environment under the laboratory condition, and test the impact strength as well as reliability of various vibration test applications. In the laboratory, with the aid of vibration testing system, simulations of reproduction of sinusoidal, random, resonant search and dwell, classical shock and road models, etc. can be achieved. It is essential for product quality assurance, new product research and development.


Labtone EV series of electromagnetic vibration testing system is specially designed to meet the need for long time operation. Vertical and horizontal vibrations can be achieved by the installation of vibration resistant base. The standard platform is equipped with high efficiency airbag shock isolation device, so that the vibration transmitted to the building can be minimized. There is no need for additional foundation in most of the cases.

A complete set of vibration testing system is composed of shaker, power amplifier and vibration measuring control system, in accordance with the relevant national and international standards (such as: MIL-STD, DIN, ISO, ASTM, IEC, ISTA, GB, GJB, JIS, BS, etc.) to provide technical support for establishing product quality inspection.

When a fault report received from customer (including telephone, message and email) LABTONE will respond within 4-8 hours (working time), provide solutions and eliminate fault within 12-24 hours. After the equipment guarantee period ended, supplier still has obligation to provide users with technical support and after-sales service.


  • Ttechnical consultation: test method, laboratory planning and suggestion.
  • Equipment selection:selection scheme,FAQ.
  • Product testing scheme.


  • Customer communication and progress report.
  • Guidance for pre-installation preparation, equipment commissioning and test run.
  • Calibration (when third party’s verification is required).

After sales

  • Technical training:operation of equipment,daily maintenance,common fault diagonsis and troubleshooting.
  • Scheduled on-site service:detection of problem as soon as possible in order to eliminate equipment and anthropogenic hazards.This is to ensure long term and stable equipment operation as well as delivery of latest technical information.
  • Technical support:special paid services are provided according to customer’s needs.


What are the most frequently asked questions?

By means of a fixture, usually aluminium or magnesium for lightness coupled with rigidity. They can be cast, or smaller fixtures machined from solid stock. Most fixtures are welded.

If we’re looking for resonances in the product we’re testing, we command the shaker to shake the product at one frequency at a time but to vary that test frequency, to sweep it over a range of frequencies. But more realistically, we command the shaker to vibrate randomly and to excite all the resonances simultaneously. Control commands go into the keyboard of a specially programmed computer.

Have you ever noticed the steering wheel moving with rather a large displacement amplitude, larger than the input to the column? That magnification is called resonance. Possibly it annoys you. There’s a slight chance that in a few years that whipping of the steering column might cause bending fatigue failure. When we shake an automotive or ship or land vehicle instrument, we’re looking for, for example, portions of printed wiring boards (PWBs) responding with greater motion than we’re inputting. That flexing may damage PWB wiring, it may damage the attached components, and it will damage the soldered connections between components and the PWB.
