Squeak & rattle & fatigue testers
Excitation in X, Y & Z Axes
Testing a component under excitation in multiple axes is not only part of many test specifications, it is often necessary to target and investigate structural weaknesses or noise sources.
The 3D shaker tables from MB Dynamics allow a wide range of parts and components to be excited in the x, y and z axes. Real-world vibration conditions and noise-critical excitation can be accurately replicated in multiple axes in the laboratory.
With excitation forces of up to 12 kN and an optional climatic package for use in a climatic chamber, the 3D shaker can be universally used for squeak and rattle tests and fatigue tests in accordance with a wide range of test specifications. The shaker tables can also be upgraded at any time for simultaneous x, y and z axis excitation or vertical pitch & roll testing by adding two additional shakers.
These 3D shakers are modular, upgradeable “universal” shakers that meet the requirements of a wide variety of OEM test specifications and will continue to grow with your test requirements into the future.
