Abstract

The invention is applicable to the technical field of wind tunnel tests, and provides a wind tunnel group high-pressure air resource consumption calculation method. The method comprises the followingsteps: constructing a topological structure model; establishing a monitoring system; acquiring the state of a test wind tunnel in the wind tunnel group, and acquiring the state of a high-pressure airsystem; obtaining a tank group pressure difference consumed by the test wind tunnel; updating the topological structure model; traversing the updated topological structure model to obtain the guaranteed volume of the wind tunnel being tested; and calculating high-pressure air resource consumption of the wind tunnel under test through a differential pressure method. The high-pressure air system comprises a high-pressure unit, a high-pressure tank group, an air conveying main pipe, air conveying branch pipes and valves. According to the method, the actual physical topological structure relationship between the high-pressure air system and the wind tunnel is expressed in a mode of constructing the model, so the method for calculating the high-pressure air resource consumption of the wind tunnel group in the embodiment of the invention can be used for automatically identifying the high-pressure tank group, the gas transmission main pipe and the gas transmission branch pipe which are used in the wind tunnel.

Description

technical field [0001] The invention belongs to the technical field of wind tunnel tests, in particular to a calculation method for high-pressure air resource consumption of a wind tunnel group. Background technique [0002] Large-scale wind tunnel equipment and facilities are important strategic resources of the country. Wind tunnel tests are required in many fields such as aerospace, ground transportation, building bridges, renewable energy, and environmental protection. According to the gas flow rate in the tunnel body, wind tunnels are generally divided into low-speed, high-speed, ultra-high-speed and other types. Each type of wind tunnel is divided into large / small and conventional according to the test section caliber, test type and test time. / special (such as icing, acoustics, low temperature, etc.), temporary impact / continuous and other different wind tunnels. [0003] The development of wind tunnel tests requires the strong guarantee of power resources such as ...
