Abstract

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.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a snow and icing wind tunnel test system and test method for a rail train bogie. Background technique [0002] As an important national infrastructure, rail transit is in the backbone position in the comprehensive transportation system and has an important impact on social and economic development. The rail transit system has significant advantages such as low energy consumption, small footprint, and light environmental pollution, and stands out among many transportation methods. [0003] my country's regional span is large, and rail trains need to adapt to complex and changeable operating environments such as strong sandstorms and strong snowstorms. In the cold winter, some areas such as Northeast my country, northern Xinjiang and the Qinghai-Tibet Plateau have heavy snowfall, which brings a series of special problems to the construction and operation of rail transit. Am...
