摘要
考虑青藏线(格-拉段)高海拔、强太阳辐射的气候特征,计算了沿线不同地区月平均太阳辐射强度,并与文献结果进行了比对.获得了列车行经不同站点时单位时间车身表面吸收的太阳辐射量及一个运行周期内吸收的太阳辐射总量,分析了各次列车对太阳辐射吸收量存在差异的原因.另外,从节能与出行便利性的角度对目前各次列车运行时刻的合理性进行了探讨.
Considering the characteristics of high altitude and high solar radiation in the region between Golmud and Lhasa on Qinghai-Tibet railway, the monthly average solar radiation intensity along the railway is calculated and the results are compared with the published results. The solar radiation absorbed by the train outer surfaces in Unit time in different regions is obtained as well as the solar radiation absorbed by the train outer surfaces in one running cycle. The reasons resulting in the discrepancy of solar radiation absorbed by the studied trains are analyzed here. In addition, the reasonability of the studied train running timetable is discussed from viewpoint of energy-saving and convenience.
