摘　　要：研究在相同的使用工况下,不同的编织层材料和中层胶厚度对液压制动软管疲劳耐久性能的影响。结果表明:液压制动软管在疲劳耐久试验中失效的主要原因是编织线相互摩擦受损,强度无法承受管路内压力;与编织层采用维纶线相比,编织层采用聚酯线时液压制动软管具有更加优异的疲劳耐久性能;随着中层胶厚度的减小,液压制动软管的屈挠疲劳耐久性能下降。The influence of different braided layer materials and middle rubber thickness on fatigue durability of hydraulic brake hose under same working conditions was studied.The results showed that,the main reason for the failure of hydraulic brake hoses in fatigue durability tests was that the braided wires were damaged by friction with each other,therefore their strength could not withstand the pressure inside the pipeline.The hydraulic brake hose using polyester yarn in the braided layer had better fatigue durability than the hydraulic brake hose using vinylon yarn.With the decrease of the thickness of the middle rubber,the flex fatigue durability of the hydraulic brake hose decreased.
