How do I accurately calculate the required force (thrust) rating for my shaker system?
Date: January 5, 2026Views: 4704
The basic formula is Force (lbf or N) = Total Moving Mass x Peak Acceleration. The “Total Moving Mass” must include your heaviest Device Under Test (DUT), its fixture, and the shaker armature/head expander. For random vibration, you must calculate using the peak acceleration in the profile, not just the GRMS value. We strongly recommend a safety margin of 30-50% over your calculated peak force to ensure headroom and system longevity. Our engineering team provides free thrust calculations as part of the consultation.
