3-axis Vibration Testing Machine With Head Expander and Vibration Controller
Vibration Test Systems
EV series of electromagnetic vibration testing system 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.

Working Principle:
Test requirements and model selection guide
To choose a suitable vibration test system, the most important thing is to know the exciting force required to perform the vibration test. To evaluate and calculate the exciting force, the following test specifications should be known:
Clear Testing Requirements:
- Frequency (Frequency Range)
- Maximum Acceleration
- Maximum Displacement
- Maximum Velocity
- Specimen Mass and Fixation
The specimen fixation is selected based on the upper limit of test frequency and specimen size, either vertical expansion platform or horizontal slip table. Specimen mass is needed to evaluate the required exciting force for vibration test.
Evaluation of Armature Mass
When evaluating the exciting force needed for vibration test, you can choose a temporary armature mass (according to the model of EV series)
