摘　　要：吊弦疲劳失效会导致高速铁路接触网系统发生弓网故障。为深入分析吊弦的疲劳耐久性能,参考相关吊弦疲劳试验标准,设计一种运行可靠、耐久性能好的接触网吊弦疲劳试验装置。该装置位移载荷可调,加载平稳,可精确控制吊弦加载力,同时具有更宽的频率加载范围。通过该疲劳试验装置,可研究吊弦在高频振动下的失效形式,为吊弦疲劳寿命预测与结构优化提供试验研究平台。Fatigue failure of droppers would result in pantograph-contact wire failure of high speed railway.A fatigue test rig for OCS droppers with reliable operation and durable performance was designed by referring to relevant standards on fatigue tests of droppers,to have in-depth study on the fatigue durability of droppers.This test rig features adjustable displacement and load,stable loading,accurate control on load to droppers and a wide frequency loading range.With the fatigue test rig,the types of failures of droppers under high-frequency vibration can be identified,providing a test and research platform for predicting the fatigue life and improving the structure of droppers.
