Design Analysis
Parts Stress & Derating
Review electrical and thermal stresses against component limits and application margins.
Purpose & Benefit
When This Activity Helps
Use before design release or when loads, temperatures or components change. Derating review helps reduce overstress and identify conditions requiring further measurement or modelling.
Project Information
Typical Inputs
The scope is tailored to the available evidence. Useful inputs include:
- Component ratings and applicable derating policy
- Steady-state loads, transients and temperatures
- Schematics, tolerances and cooling assumptions
Engineering Approach
How SPACEREL Supports Your Project
SPACEREL compares expected stresses with ratings and agreed limits, considering tolerances, self-heating and credible worst-case conditions. Exceptions and uncertain inputs are recorded for design action or further verification.
Documented Outcomes
Typical Deliverables
Deliverables are agreed before work starts and can include:
- Parts stress and derating assessment
- Margin and exception register
- Recommendations for measurement or design changes
