| Abstract: | 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. |
