【Abstract】 [Objective] Based on the “八-shaped” layout scheme of the rigid catenary stagger value, the factors affecting the pantograph-catenary(PC) wear of the rigid catenary are analyzed and measures to improve the wear are proposed. [Method] The principles of electrical wear and mechanical wear, and the measures to solve these two types of PC wear are introduced. One of the factors affecting the mechanical wear between the pantograph and the catenary, that is, the “layout mode of the stagger value” is studied with emphasis. Combining with actual engineering projects and using quantitative statistical methods, the influence of the “八-shaped” layout scheme of the rigid catenary stagger value on the PC wear is analyzed from three aspects: the magnitude of the sweeping frequency of the stagger value, the consistency of the sweeping frequencies of the stagger values at the suspension points within two adjacent anchor sections, and the position of the suspension points at the joints relative to the track center line. [Result & Conclusion] When the “八-shaped” layout scheme of the stagger value is adopted for the rigid catenary, measures such as increasing moderately the sweeping frequency value of the stagger value, maintaining the consistency of the stagger value sweeping frequencies at the suspension points within two adjacent anchor sections, and keeping the joint suspension points located on the same side of the track center line, are conducive to improving the uniformity of the wear of the carbon slide plate.更多还原
