摘要
介绍了接触网刚性悬挂一些特点,在同柔性悬挂平面布置相比较后,提出了刚性悬挂平面布置的3个决定因素:跨距长度、锚段长度、δ值。并提出了δ值计算新思路,建立了相应的数学模型。为刚性悬挂在电气化铁路及城市轨道交通的设计和运行提供了理论支持。
Some features of rigid suspension in OCS are introduced briefly in this paper. After comparing the difference with flexible catenary, three primary factors in the layout plan of rigid suspension are suggested: the length of span, the length of section and the δ value. A new method to calculate the δ value is put forward and the corresponding mathematical model is set up. All these give a theoretic support in rigid suspension being used in railway electrification and urban rail transportation.
