摘要
Abstract
Objective Fracture failure analysis of vehicle components was conducted to determine whether their fracture occurred prior to or as a result of the traffic accident.Methods A preliminary analysis of potential accident causes was carried out based on the client's requirements,accident details,and relevant case files.An appropriate appraisal strategy,including dynamic,static,or component failure inspection,was then determined.Where component failure was identified as a contributing factor to the accident,dedicated failure analysis was carried out.Fractographic examination results were subsequently integrated with other relevant factors for comprehensive evaluation to form expert conclusions.Results The proposed methodology was applied in actual traffic accident cases.Through macroscopic and microscopic examination of fracture surface morphology,metallographic structure,and chemical composition of the failed components,the effectiveness of the analytical approach was validated.Conclusion This method enables accurate identification of accident causes,and offers a valuable reference for the investigation of similar component fracture failures in future traffic accident cases.关键词
