Title:
AIR DUCT SYSTEM SIMULATION OPERATION TEST BENCH AND EXPERIMENT TEST METHOD
Document Type and Number:
WIPO Patent Application WO/2024/067487
Kind Code:
A1
Abstract:
An air duct system simulation operation test bench (100). The air duct system simulation operation test bench (100) comprises: a test air duct (101), which is a test main body of a fan air duct system; a cooling fan (102), which is mounted on the test air duct (101) and is used for providing an air volume source for the entire fan air duct system; a hard air duct (103), which is connected to the test air duct (101) and a traction fan (105), the flow rate of air in the hard air duct (103) being changed by means of adjustment of an internal rotary cover plate, so as to simulate working conditions for different degrees of blockage at an air outlet of the traction fan (105); a soft air duct (104), which is used for perfecting the integrity of the fan air duct system, so as to reflect the real situations of the fan air duct system during installation on trains; and a traction fan (105), which is connected to a corresponding position on the test air duct (101) by means of the hard air duct (103) and the soft air duct (104). Also provided are an experiment test method and experiment test device (300) for the typical working condition of an air duct system, an electronic apparatus (400) and a computer-readable storage medium. The air duct system simulation operation test platform (100) and the test method provide data support for the model selection of cooling fans and the design verification of air duct structure systems, and facilitate the safe operation of high-speed multiple-unit trains.
