Acoustic, Noise, Vibration & NVH Products calculator
Shaker Table Utilization Calculator
Shaker tables are often bottlenecks for vibration durability, modal, and NVH validation work. This calculator compares booked hours with available hours so lab managers can see utilization and schedule margin before committing more tests.
What this calculator does
- Calculate booked shaker table time as a percent of available lab time and compare against a utilization target.
- a vibration lab manager needs to know whether a shaker table schedule is overbooked or underused
- Returns the percent of available shaker table time already booked.
Formula used
- Shaker utilization = booked shaker time รท available shaker time
- Gap to target = target utilization - shaker utilization
Inputs explained
- Booked shaker time: undefined
- Available shaker time: undefined
- Target utilization: undefined
How to use the result
- Use it for weekly lab planning, validation program loading, overtime decisions, and outside-lab make/buy reviews.
- It does not account for fixture build, control tuning, channel setup, or invalid tests unless those hours are included in booked time.
Common questions
- Should setup time be booked? Yes if it blocks the table from another test. Include fixture changes, instrumentation, and profile tuning.
- What does a negative gap mean? Utilization is above the target, so the lab may need overtime, schedule relief, or another table.
- Can 100% utilization be bad? Yes. A fully booked shaker leaves no room for retests, fixture issues, or urgent failures.
- How does this differ from chamber capacity? This page measures time utilization; chamber capacity estimates count of valid tests.
