Space Payload & Avionics Manufacturing worked example

Vibration Test Schedule at 12% fixture setup and handling allowance: a worked example

What does the result look like when fixture setup and handling allowance reaches 12%? The full calculation is worked below with real intermediate numbers. Use it when vibration test schedule in space payload and avionics manufacturing is changing rate or allowance and you want to see the impact.

The inputs for this scenario

  • Units to vibration test in the lot: 120 units (unchanged)
  • Shaker table throughput per minute: 12 units / min (unchanged)
  • Fixture setup and handling allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base vibration test schedule time = vibration test schedule workload รท vibration test schedule completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required vibration test schedule time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base vibration test schedule time.
  • At this operating point the engine returns 12 % for vibration test schedule allowance applied.
  • At this operating point the engine returns 12 pieces / min for vibration test schedule completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where fixture setup and handling allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • A figure at this level is achievable when fixture setup and handling allowance is genuinely sustained, not just peaked for a shift. It assumes a steady per-unit throughput and does not model channel dropouts, retest after a resonance shift, or the fact that qual-level runs on a single unit can take far longer than acceptance-level runs on the rest of the lot.

Results at a glance

  • Required vibration test schedule time: 11.2 hr (headline result)
  • Base vibration test schedule time: 10 hr
  • Vibration test schedule allowance applied: 12 %
  • Vibration test schedule completion rate: 12 pieces / min
