摘　　要：通过分析接触网刚性悬挂的特点,从节约投资及提高和改善接触网受流质量入手,阐述不同跨距下汇流排的振动特性、凸凹不平直度与运行速度的关系、汇流排挠度对运行速度的影响、锚段关节及道岔处特殊点的特性,得出合理的接触网刚性跨距布置方案。Through analyzing the characteristics of rigid suspension catenary, for the sake of saving investment and improving the current collecting quality of the catenary, the paper describes bus vration characteristics, relation of uneven and nonstraightness with running speed, effect of bus deflection on the operation speed, influence of the anchor segment joints and switch special point characteristics under different spans of the catenary, thereupon the reasonable contact rigid span arrangement scheme is obtained.
