What are Shake Tables & Modal Analysis?

At its core, a Shake Table is a high-performance vibration platform used to subject a structure or component to controlled mechanical stress. It mimics the "shakes" a product might experience in the real world—whether that’s a bumpy road, a jet engine's roar, or a massive earthquake.

Modal Analysis is the "brain" behind the shake. It is the process of testing a structure to find its natural frequencies and damping properties. By shaking a component and measuring how it responds, we can identify "weak spots" where the structure might vibrate too much and eventually break or fail.

Key Features

• Precision Motion Control: Easily simulate sine-sweeps, random vibrations, or specific shock pulses with absolute accuracy.

• High Payload Capacity: Built with reinforced frames to handle everything from delicate electronics to heavy industrial components.

• Real-Time Data Mapping: Integrated sensors capture microscopic movements, providing instant graphs of frequency response and damping.

• Safety Overrides: Built-in emergency limits that automatically shut down the system if vibrations exceed safe boundaries, protecting your prototypes.

Applications

• Civil Engineering: Testing scale models of buildings and bridges for earthquake resistance.

• Automotive & Aerospace: Simulating road wear for cars or the extreme "g-force" vibrations of a rocket launch.

• Electronics: Ensuring sensitive circuit boards don’t rattle apart during shipping or high-speed operation.

• Defense: Testing the ruggedness of equipment designed for harsh, high-impact environments.
