【摘要】 发动机冷却器是公路车辆和各类特种车辆必备的组成部分，冷却器的可靠性、冷却器软管的寿命直接影响整车质量。研制一套能为冷却器软管提供与车辆实际工况类似试验环境的疲劳试验系统，用于检测冷却器软管的寿命。该系统具有扭转加载功能，扭转频率可通过软件设置，扭转幅值可通过偏心轮机构手动调节，自动采集扭转角度数据，实时显示加载曲线，并能够保存测试数据。更多还原

【Abstract】 Engine cooler is an essential component of road vehicles and various types of special vehicles, and the reliability of the cooler and the life of the cooler hose directly affect the overall quality of the vehicle. A set of fatigue test system that can provide test environments similar to the actual working conditions of the vehicle for the cooler hose is developed to test the life of the cooler hose. The system has a torsion loading function, with torsion frequency set by software and torsion amplitude manually adjusted by the eccentric wheel mechanism, automatically acquires torsion angle data, displays the realtime loading curve and saves the test data.更多还原
