The invention discloses a rail
train bogie snow accumulation and
icing wind tunnel test
system and test method. The test
system comprises a
backflow type wind tunnel flow channel which comprises a power section, a
snow making section, a first corner section, a test section, a second corner section and a surface air cooler section which are connected in sequence; and the surface air cooler section is connected with the power section. An axial flow fan and a supercooled water spraying device are arranged in the power section, a rotary
test bench is arranged in the test section, a
bogie is arranged on the rotary
test bench, a wind and
snow separation device is arranged in the second corner section, a surface air cooler is mounted in the surface air cooler section, and a water spraying device is arranged on the
bogie. The
system also includes a controller which is connected with the rotary
test bench, the water spraying device and the axial flow fan. The test system not only can truly simulate the dynamic process of snow accumulation and
icing in a bogie area when a rail
train operates in a windy and snowy environment and determine the cause of the snow accumulation and
icing problem in the bogie area, but also can evaluate the snow accumulation and icing prevention effect of the snow accumulation prevention structure and device on the bogie area.
