Failure Analysis and Adaptation for Hydraulic System in a Transportation Vehicle

This paper provides failure analysis on abnormal phenomena such as tearing of hinge, unintentional automatic extension and retraction of the locking pin during the first adjustment procedure of a transportation vehicle. The fundamental working principle of the cap pushing hydraulic system and locking hydraulic system is briefly introduced. Defect in hydraulic system design and causes of failure are pointed out through analysis and corresponding adaptations are proposed. Through experiments, the correctness and effectiveness of these adaptations are positively verified.
