自卸汽车液压举升系统隐形缺陷和潜在失效模式分析
|
摘要
简述了自卸汽车液压举升系统工作原理和结构特征;在总结实际司法鉴定案例基础上分析了自卸汽车发生货箱自行升起的原因和在用自卸汽车液压举升系统存在的隐形缺陷和潜在失效模式;提出了基于车辆行驶安全的自卸汽车液压举升系统设计要求。
Operation principle and structure characteristic of dump truck hydraulic lifting system are discussed. By analyzing the cause of the abnormal self-rising of dump truck crate based on the actual case of judicial authentication,the hidden defects and potential failure modes existing in the dump truck hydraulic lifting system are discovered and researched. Design requirements are presented based on the traffic safety of dump truck hydraulic lifting system.
