摘要
为掌握兰新客运专线高寒抗风沙动车组设备舱在各种工况下差压的变化规律,采用在设备舱内外布置差压传感器和以太网方式采集测试数据的方法,通过跟踪设备舱的差压气动载荷,获得测试数据,为设备舱强度评估提供理论计算依据和边界条件。
In order to grasp the changing law of the equipment cabin differential pressure for Lanzhou-Xinjiang passenger dedicated line vehicles under high,could and wind resistant conditions,differential pressure sensors and Ethernet are installed inside and outside the equipment cabin to collect the test data.By tracking the differential pressure aerodynamic load of the equipment cabin,the test data are obtained,which provide theoretical calculation basis and boundary conditions for the strength evaluation of the equipment cabin.
