摘要
基于隧道气动效应等指标进行检测,进一步验证斜井处气动力和列车风对于列车运行平稳性的影响,在西成客专阜川隧道,采用测试动车组和相关检测设备在规定测试速度下对隧道气动效应等指标进行检测,并详细记录试验数据,对试验工程作现场原型观测,详细记录检测数据;进而分析各项数据,修正、完善气动效应,对检测结果进行对比、校正。该试验资料为动车组晃车原因分析提供技术支持。
Based on the tunnel aerodynamic effect and other indicators, tests were carried out to further verify the impact of aerodynamic force and train-induced wind at inclined shaft on train running smoothness. In Fuchuan Tunnel of Xi’an-Chengdu Passenger Dedicated Line, the aerodynamic effects of the tunnel were recorded in detail by using test EMU and related equipment at specified speed. Field prototype observation of the test project was carried out and the test data were recorded in detail, then based on analyses of the data, and modification and improvement of the aerodynamic effect, the test results were compared and corrected. The test data provide technical support for the analysis of the cause of EMU train shaking.
