Vibration Analysis – Machines, Piping, Structures and Foundations
Is a pump, pipe, platform or machine shaking too much? SLETEC finds out why and how to fix it. We use modal analysis, harmonic response, resonance checks and dynamic foundation analysis to show the natural frequencies, the cause and the right fix.
Our vibration studies cover rotating equipment bases, compressor and pump foundations (ACI 351.3, DIN 4024), piping vibration including flow-induced (FIV) and acoustic-induced vibration (AIV), small-bore connections, platforms, floors and tall stacks. We give clear recommendations such as stiffeners, supports, bracing or foundation changes, with drawings.

Frequently Asked Questions
What causes vibration in pumps and pipes?
Common causes are resonance (natural frequency close to running speed), weak supports, unbalance, misalignment and flow or pressure pulsation. Our analysis identifies which one applies.
Can you fix vibration on an existing platform or pipe?
Yes. We model the existing structure, find the cause and design stiffeners, braces or supports with fabrication drawings.
Do you analyse machine foundations?
Yes. We do dynamic analysis of pump, compressor and fan foundations to ACI 351.3 and DIN 4024.
