A comprehensive durability test for automotive electrical equipment
simulates years of real-world use in a lab, combining environmental stress (extreme temps, humidity, corrosion), mechanical loads (vibration, shock, fatigue), and electrical cycling (voltage/current fluctuations, EMC) to identify failures like shorts, demagnetization, or connector wear, ensuring components like relays, wiring, and sensors meet safety, performance, and lifecycle standards (e.g., SAE/USCAR-2) before production, using accelerated testing and real-world data to predict lifespan and prevent costly recalls. Key Testing Categories
- Environmental Testing:
- Temperature Cycling: Rapid changes between hot and cold to check for expansion/contraction damage.
- Humidity/Corrosion: Moisture resistance to prevent shorts and corrosion (e.g., salt spray).
- Ingress Protection (IP): Testing seals against dust and water, crucial for under-hood parts.
- Mechanical Testing:
- Vibration & Shock: Simulates road bumps, engine vibration on connectors, solder joints, and overall structure.
- Fatigue Testing: Repeated stress (e.g., switch clicks, connector insertions) to find fatigue points.
- Load Testing: Applying mechanical forces to check structural integrity.
- Electrical & EMC Testing:
- EMC (Electromagnetic Compatibility): Ensures components don't interfere with each other (emissions/immunity).
- Electrical Cycling: Repeated on/off cycles, voltage/current variations, and signal integrity checks.
- Insulation Resistance/Continuity: Verifies electrical pathways remain intact.
Common Automotive Standards & Methods
- Data-Driven Profiles: Real-world vehicle data (speed, torque) creates accelerated lab profiles.
- SAE/USCAR-2: Common standard for connectors and terminals, focusing on performance across development stages.
- GMW3172: General Motors standard for electrical/electronic component validation, covering environmental, durability, and electrical needs.
- Accelerated Life Testing: Pushing components beyond normal use to speed up failure identification.
Typical Equipment Tested
- Relays, fuses, switches, wiring harnesses, connectors, junction boxes, sensors, motors, and inverters.
Goal
- To replicate years of use in a condensed timeframe, predict failure points, improve design, ensure safety, and meet regulatory compliance.
