防风栅可降低铁道车辆在横风作用下铁道车辆所受的气动力,其抗风性能受许多因素影响。针对这一问题,根据日本对防风栅、车辆、线路等组合进行一系列风洞模型试验,以及得到的试验数据,分普通型防风栅与新型防风栅情况,对防风栅降低铁道车辆所受气动侧向力的抗风性能的主要影响因素,以及防风栅实际应用情况等进行分析和讨论,最后根据国内对防风栅研究与应用的现状提出相关建议。
Windproof grille reduces the aerodynamic forces on railway vehicles under the action of transverse wind. The wind resistance can be affected by many factors. In response to this problem, according to a series of wind tunnel model tests carried out by Japan on the combinations of wind screens, vehicles and lines, and the test data obtained, the common windshield and the new windshield are used to reduce the air pressure The main influencing factors of the wind resistance performance of the lateral force and the actual application situation of the windproof grid are analyzed and discussed. Finally, some suggestions are put forward according to the domestic situation of the research and application of the wind shield.
