Introduction

Analysis of core design requirements

Specification classification and interface adaptation

Space station payloads are divided into six categories, including SPU laboratory cabinet standard unit, SDU guide rail installation device, etc., forming a clearly subdivided standard system according to the installation location:

Payload type	Core size (mm)	Upper mass limit (kg)
SPU 4x unit	460×545×555.5	130
SDU II type	440×600×502	85.5
Medium-sized standard outboard	≤600×600×500	Dynamic accounting

Key technical indicators comparison

The core number supervision strategy adopts three-level redundancy management:

Power supply module: dual topology to ensure 100% fault tolerance coverage
Moving parts: Power ratio coefficient ≥3 to resist extreme environments
Electromagnetic isolation: The isolation impedance of the same power supply loop is strictly ≥1MΩ

Validation process innovation

Shock spectrum during single-machine stress verification covers 120% of the design envelope
Full-load vacuum thermal cycle adopts a gradient of -40°C/70°C for a harsh test
Extravehicular nuclear irradiation equivalent test exceeds the standard 12-hour continuous peak
