승용차량용 쇽업소버의 열화분석 사례연구

다국어 초록 (Multilingual Abstract)

Purpose: The purpose of this study is to estimate the lifetime of commercial passenger vehicles shock absorber using degradation test and data.
Method: The degradation factor of shock absorber was determined to be a damping force using FMEA. Degradation test was performed on damping force under real world usage condition and analysed the degradation data.
Results: To estimate the lifetime of shock absorber, a degradation model was developed and a numerical example was provided.
Conclusion: Evaluation of the lifetime of commercial and military vehicles shock absorber will be possible by using the proposed degradation analysis method.
