The invention a continuous high-speed wind tunnel experiment section fast replacement device, which is formed by four motors in same power, four speed reducers in same reduction ratio, four wheel axles, an electric appliance control box and cables. The four motors and the four speed reducers are installed cooperatively with four wheels of a wind tunnel experiment section; the speed reducers are mounted on wheel bases, and are connected with the wheels through the wheel axles respectively to realize transmission of driving force; one motor and one speed reducer form a set of independent driving device; the motor is directly connected with corresponding the speed reducer; the electric appliance control box is connected with the four sets of independent driving devices through the cables; and start and stop and rotation speed of the four sets of driving devices are controlled independently through the electric appliance control box. The device effectively guarantees alignment precision of the wind tunnel experiment segment, improves wind tunnel experiment section replacement efficiency, reduces safety risks of personnel and equipment in the section replacement process and provides technical support for fast replacement and accurate installation of the continuous high-speed wind tunnel experiment section.
Description
technical field [0001] The invention relates to the design field of a moving and changing device for a wind tunnel test section, in particular to a fast section changing device for a continuous high-speed wind tunnel test section. Background technique [0002] The wind tunnel is an artificially generated and controlled airflow, which is used to simulate the flow of air around the aircraft or entity, and can measure the effect of the airflow on the entity and observe physical phenomena. It is a kind of pipe-shaped experimental equipment for aerodynamic experiments One of the most used and effective tools. Wind tunnels are widely used to study the basic laws of aerodynamics, to verify and develop relevant theories, and directly serve the development of various aircraft, through wind tunnel experiments to determine the aerodynamic layout of the aircraft and evaluate its aerodynamic performance. Wind tunnel experiments are an indispensable part of aircraft development. It not ...
