Big and small systems or a large force system are used to meet the requirement of two types of specimens. The former needs large cost and the latter wastes resources.
A set of vibration shaker equipping with two sets of horizontal slip tables ( large and small) is used, to achieve the connection at two horizontal directions only if the horizontal directions only if the shaker rotates 180°, thus meeting both large size specimen low acceleration tests and small size specimen high acceleration tests.
Specificity of the vibration test:
- Large size and low acceleration
- Small size and high acceleration
- Test under X, Y and Z directions
