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:
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 tests.
When evaluating the exciting force needed for vibration test, you can choose a temporary armature mass (according to the model of EV series)
