ASA automotive exterior part comprehensive failure
문제 현상
ASA automotive rearview mirror housings show batch cracking, fading and assembly loosening; multiple failure modes occur concurrently and a single measure cannot radically cure.
원인 분석
Under outdoor conditions, ultraviolet, thermal cycling, vibration and chemical contact couple multiple factors; processing internal stress, material batch differences and design stress concentration superimpose; single-link optimization is insufficient to cover system risks.
해결 방법
①Systematic investigation: verify material batch, process stress, design structure and assembly conditions item by item; ②accelerated aging and vibration combined test reproduces failure; ③FMEA sorts out the risk chain; ④combined verification of improvement measures.
핵심 요약
ASA automotive part failures are mostly multi-factor coupling; systematic investigation is better than single-point trial and error; combined condition testing is a reliable path for reproduction and verification.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
