Design and Optimization of Rotating Mechanism for Wind Load Test-Bed of Aerodynamic Brake

Abstract:

To adjust the angle between braking panel of aerodynamic brake and the wind direction, the duct and the direction of the wind are fixed, and the panel is rotated horizontally. So a rotating mechanism should be designed out to make the aerodynamic braking equipment rotate horizontally. This paper emphatically completes the design of rotating control system. The rotating direction is controlled by two bevel gears; magnetic powder clutch is used to simplify the organization, optimize the control mechanism, and let electric signal control the movement of clutch directly; the rotary supporting mechanism is consist of slewing bear which have two functions, supporting and rotating, and this mechanism is more compact and stable. In a word, this mechanism realizes horizontal rotating of the test-bed. And it lays the foundation of experiments about aerodynamic braking system.
