2023年第1期接触网吊弦结构的优化设计王增辉,巨子琪(西安交通工程学院,西安710300)摘要:当列车在行进过程中,列车受电弓会给予接触线一个抬升力的作用,最终抬升力会作用在整体吊弦处从而使整体吊弦发生弯曲现象,并且当列车驶离后还会产生一定的振动能量从而影响整体吊弦的使用寿命。基于此类情况的发生,本文设计一种吸能缓冲装置,通过减小整体吊弦的弯曲量和能够吸收一部分振动能量从而增加整体吊弦的使用寿命。关键词:整体吊弦;抬升力;吸能缓冲装置中图分类号:U264文献标识码:A文章编号:1674-957X(2023)01-0090-04OptimizationDesignofCatenaryDropperStructureWangZeng-hui,JuZi-qi(Xi’anTrafficEngineeringInstitute,Xi’an710300,China)Abstract:Whenthetrainisrunning,thepantographofthetrainwillgivealiftingforcetothecontactline,andtheliftingforcewilleventuallyactontheintegralsuspensionstring,whichwillcausetheintegralsuspensionstringtobend,andwhenthetrainleaves,acertainamountofvibrationenergywillbegenerated,whichwillaf-fecttheservicelifeoftheintegralsuspensionstring.Basedontheoccurrenceofthiskindofsituation,thispaperdesignsanenergyabsorptionbufferdevice,whichcanincreasetheservicelifeoftheintegraldropperbyreducingthebendingamountoftheintegraldropperandabsorbingpartofthevibrationenergy.Keywords:Integraldropper;Liftingforce;Energyabsorbingbuffer...
