The Contractor shall perform electrical and mechanical parts/circuits analysis for all new designs and proposed design changes. An electrical parts/circuits analysis shall be prepared and accomplished and the results shall be reported and discussed at Design Reviews. Results and methods of such analysis shall be available and provided to the Government as requested. The following requirements shall be incorporated:
a. Environmental Requirements - The Contractor shall ensure that all new design and all proposed design changes meet the environmental requirements specified in the Design Reference Mission Profile and applicable performance specification requirements.
b. Thermal Design Criteria - The Contractor shall establish thermal design criteria based on measurements and analysis of the environmental requirements specified in the Design Reference Mission Profile and applicable performance specification requirements to determine anticipated operational temperatures for each mechanical or electrical assembly and component involved in a new design or proposed design change. Self-induced temperature rise due to internal power dissipation shall be included in the determination of anticipated temperatures. Provisions shall be made for reassessment of the thermal design criteria as the design progresses and measurement data become available including accomplishment of thermal surveys to verify expected/anticipated temperatures. The Contractor's criteria shall ensure that assemblies and components are capable of functioning in a temperature environment that does not exceed the item's ratings, with provisions for appropriate safety margins. Thermal design guidelines are provided by MIL-HDBK-251.
c. Tolerance Analysis - The Contractor shall perform tolerance analysis on both mechanical and electrical hardware to ensure achievement of system performance parameters. The analysis shall incorporate parameters for electrical circuits (supply voltages, signal levels, etc.).
d. Mechanical Stress Analysis - For non-electrical parts, the Contractor shall conduct a mechanical/structural stress analysis to verify that appropriate margins of safety exist when compared to the mechanical and structural criteria of the structural dynamics reports and the applicable performance specification requirements. The stress analysis shall be conducted at worst-case environmental and load conditions.
e. Electrical/Electronic Stress Analysis - The Contractor shall conduct electrical/electronic stress analysis utilizing NAVSEA TE000-AB-GTP-010 or best industry practice and shall present the analysis at the appropriate design review.
