摘　　要：吊弦疲劳试验分析对高速铁路接触网性能研究具有重要意义。本文在参考柔性吊弦疲劳试验标准的基础上,提出一款针对刚性吊弦的疲劳试验台设计方案,该试验台采用压缩载荷与力载荷单独加载方式,可施加稳定且连续可调的力载荷,同时加载频率在中、高频率。通过试验台对刚性吊弦进行试验,为刚性吊弦的疲劳损伤机理研究、加速老化试验方法形成提供数据支持。The dropper fatigue test and analyzing are of great importance for the studies on the performance of OCS of high-speed railway.The paper,with reference of flexible dropper fatigue test standard,puts forward a scheme for design of a fatigue test bench with regard to the rigid droppers.The test bench adopts a separate loading method of compression load and force load,which can apply stable and continuously adjustable force loads,and the loading frequency is at medium and high frequencies.The testing of rigid droppers on the test bench is able to provide data support for studies of fatigue damage mechanisms and establish the accelerated aging test methods for rigid droppers.
