Description

Technical Field

[0001] This utility model relates to the field of wind tunnel testing technology, and in particular to a model mounting device for wind tunnel testing. Background Technology

[0002] Wind tunnel testing is an experimental method that uses wind tunnel equipment to simulate airflow environments and study the aerodynamic properties of objects in airflow. Its core is to drive airflow through a model (such as an aircraft, car, or building) using a fan, and then use pressure sensors, anemometers, and other equipment to measure the forces (drag, lift, torque, etc.) exerted by the airflow on the object, analyzing its aerodynamic performance. During the test, wind speed, airflow state (laminar / turbulent), and environmental parameters (temperature, humidity) can be precisely controlled to reproduce different operating conditions. Wind tunnels are categorized by function into low-speed, high-speed, and transonic types, and are widely used in aerospace (aircraft aerodynamic layout optimization), automotive engineering (reducing wind noise and energy consumption), and bridge construction (wind resistance stability testing). They are an important technical means to verify theoretical designs and optimize the shape of objects, providing crucial data support for engineering practice. However, current installation and fixing devices cannot automatically and flexibly change the model's position during use, requiring continuous manual adjustments and reducing testing efficiency.

Simultaneously, starting the first motor 12 drives the second gear 11 to rotate, which in turn rotates the first gear 10, allowing the model to rotate for adjustment. When the second motor 16 is started, it drives the third gear 17 to rotate, which in turn meshes with the fourth gear 18, causing the fourth gear 18 to rotate its groove. This, in turn, causes the rotating shaft 19 to rotate the rotating component 20, adjusting the model's angle. When the third motor 22 is started, it drives the threaded rod 24 to rotate, which in turn drives the lifting key for raising and lowering. The lifting component 25 moves synchronously with the mounting body 2, completing the height adjustment of the model. Through the coordinated operation of these multiple modules, different positions of the model can be adjusted, enabling wind tunnel tests at different locations.
