Abstract
A device for testing a flow field state within a high-speed train bogie cabin; the periphery of a bogie consists of apron plates and end plates; the test device comprises: a plurality of test points evenly distributed on the inner walls of the apron plates and end plates, a plurality of image pickup devices installed in the bogie cabin, a smoke generator communicating with an inner cavity of the bogie via pipes, and one or more smoke exits provided on top of the bogie; each test point is connected to a test tape, and the distance between the test points is more than twice the test tape length. The test device monitors and records in real time the air flow direction at the end plates and apron plates by means of viewing of a fluorescent test tape. Also provided is a method of testing a flow field state within a high-speed train bogie cabin.
