Shale shakers are components of drilling equipment used in many industries, such as coal cleaning, mining, oil and gas drilling. They are the first phase of a solids control system on a drilling rig, and are used to remove large solids from the drilling fluid ("mud").. Drilling fluids are integral to the drilling process and, among other functions, serve to lubricate and cool the drill bit as

Vibration testing on electrodynamic or hydraulic vertical shakers (and on shakerdriven horizontal slip tables) is done for a broad range of reasons. These include demonstration of compliance with standards, new design qualification, stress screening, fatigue life evaluation, shock and earthquake survivability demonstration and various product preshipment audit and burnin tests.

Structural Vibration (Dynamic) Analysis predicts the dynamic effects of the machinery itself so that resonance can be avoided. Dynamic loads include imbalance, misalignment, pulsation forces, crosshead guide forces, cylinder gas forces, moments, and other forces (see Figure 5 for an example of dynamic forces in a reciprocating compressor).

The structure under test needs to be excited and produce enough response across the measurement points on the structure under test. Typically, impact hammer, single shaker, or multiple shakers can be used to excite the DUT in the lab. In the field, operational responses can be measured with no excitation force available for some tests.
