摘要

摘要:
为了分析运行效率更高的双源动车组在青藏线（格尔木—拉萨段）运行的可行性，建立机车动力学模型并进行了验证；采用动力学方法研究了双源动车组机车（动车）和青藏线成熟运营的HXN₃内燃机车在直线段、曲线段和坡道上的牵引黏着系数、牵引力、蠕滑率与速度之间的关系；通过对比2个机车的动力学响应，验证牵引工况下双源动车组的黏着特性. 通过分析可以发现：1）机车的牵引黏着系数与机车的牵引力成正比，当车速在40～120 km/h时，双源动车组机车的黏着系数由0.19降低至0.09，黏着富裕度则由59.0%提高至85.7%；2）在直线段和坡道情况下，双源动车组的黏着富裕度均大于HXN₃机车，对适应恶劣外界环境引起的轮轨黏着下降能力更强，对高原环境的适应性更优；3）曲线段，忽略结构引起的黏降差异，R300 m曲线时，双源动车组和HXN₃型机车的黏降幅度分别为6.3%和6.8%，R800 m曲线时，HXN₃型机车曲线黏降幅度为3.0%，而双源动车组低于限值，可以保证有足够的黏着.

Abstract:
In order to analyze the feasibility of a dual-source-powered electric multiple unit (EMU) with enhanced operational efficiency on the Qinghai–Xizang Line (Golmud–Lhasa section), the dynamics model of EMU was established and verified. A dynamic method was adopted to study the relationship among the traction adhesion coefficients, traction force, creepage, and speed for the dual-source-powered EMU and the HXN₃ internal combustion locomotive operating on the straight sections, curved sections, and ramps of the Qinghai–Xizang Line. The adhesion characteristics of dual-source-powered EMU under traction conditions were validated by comparing the dynamic responses of the two locomotives. The analysis finds that: 1) The traction adhesion coefficients of the locomotives are proportional to their traction force. Moreover, within the speed range of 40–120 km/h, the adhesion coefficient of the dual-source-powered EMU decreases from 0.19 to 0.09, while the adhesion affluence increases from 59.0% to 85.7%. 2) The adhesion affluence of the dual-source-powered EMU is superior to that of the HXN₃ locomotive in both straight sections and ramps, thereby enhancing its ability to cope with low wheel-rail adhesion conditions in harsh external environments and exhibiting better adaptability in plateau environments. 3) In the curved section, by ignoring the structure-induced adhesion reduction difference, the adhesion reduction amplitudes of the dual-source-powered EMU and HXN₃ locomotive are 6.3% and 6.8%, respectively, at R300 m curve. At the R800 m curve, the HXN₃ locomotive demonstrates an adhesion reduction amplitude of 3.0%, while the adhesion reduction amplitude of the dual-source-powered EMU is below the threshold value, ensuring sufficient adhesion.
