系统分析青藏铁路自然条件对高原铁路大型养路机械的影响

摘要

Based on the field test and documents,the paper summarizes the special climate along Qinghai-Tibet Railway and analyzes the difficulties in electrical system,engine,oxygen supply system,hydraulic system.And for the solution of the problems of safety,comfort,and reliability,effective measures are put forward to improve the performance of high alti-tude large maintenance machinery,which can provide references and guidances for research and development of China high altitude railway maintenance technology and equipment.%借鉴施工人员现场试验和文献资料，归纳总结青藏铁路特殊气候条件，分析在电气系统、发动机、供氧系统、液压系统等方面必须解决的难点和为改善舒适性、安全性和可靠性所要面对的问题，提出在设计中采用改进高原大型养路机械的有效措施。可对我国高原铁路的养护设计与装备的研究开发提供参考价值和指导作用。
