汇流排型材在重力作用下最大挠度与其截面参数关系探讨

Discussion on Relations between Maximum Deflection and Cross Section Parameters of Busbar Profile under Effect of Gravity

以电气化铁路刚性悬挂接触网汇流排为例,通过求解型材在重力作用下自然下垂所形成的挠度曲线方程,确定型材在自然弯曲下的最大挠度,并讨论该类型材的截面参数,寻找型材在重力作用下满足挠度要求的方法,为型材截面设计提供参考依据。

Taking the busbar of rigid suspension of OCS of electrified railway as an example,through calculation of the equation of deflection curve formed under gravity of natural sagging of profile,the maximum deflection of profile is determined.The cross section parameters of the profile are discussed for seeking the methods meeting the requirements of deflection of the profile under the gravity,providing reference for design of cross section of the profile.
