- Large mounting surface
- 1.0 in. p-p stroke
- Horizontal and vertical testing
- Lightweight magnesium table
The DB-140 flexure table offers a larger mounting
surface with high-load carrying capability for applications where
lower acceleration levels are needed with large or heavy loads. The
flexure table suspension system utilizes highly damped, oversized
linear flexures and dynamic absorbers to provide support and guidance
without the use of heavy granite surface plates or oil. Since no oil
is used, the complete base system can be rotated into the vertical
position to facilitate vertical axis guided testing. Base mounting
holes are provided on the bottom as well as the rear of the base to
facilitate vertical flexure table operation. The shaker can also be
disconnected from the table, rotated to the vertical position, and
then used as a normal vertical shaker without the additional weight
of the table. Rotating the base with the shaker in this position also
allows horizontal operation without the flexure table. The base is
supplied with removable carrying handles.
