Problems solved by technology

However, this method cannot completely decouple the bending and torsional stiffness. The torsion spring still provides a certain bending stiffness, and the circular shaft needs two bearings to support the structure.

Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0020] figure 1 It is a schematic diagram of the two-degree-of-freedom support mechanism of the rudder surface model. The two-degree-of-freedom support mechanism of the rudder surface model includes: rudder surface splint 2, curved spring piece 3, decoupling splint 4, torsion spring piece 5, support splint 6 and base 7, the rudder surface The surface model two-degree-of-freedom support mechanism is used to support the rudder surface model 1.

[0021] Such as figure 1 , figure 2 As shown, the upper end of the rudder surface splint 2 clamps the root of the rudder surface model 1 by screws or rivets, and the lower end of the rudder surface splint 2 clamps one end of the curved spring leaf 3 by screws or rivets. The two ends of the decoupling splint 4 respectively clamp the other end of the bending spring piece 3 and one end of the torsion ...

Abstract

The invention discloses a control plane model two-degree-of-freedom supporting mechanism. The control plane model two-degree-of-freedom supporting mechanism comprises a control plane clamping plate, a bent leaf spring, a decoupling clamping plate, a torsion leaf spring, a support clamping plate and a base. A control plane model is clamped by the upper end of the control plane clamping plate. The bent leaf spring is clamped by the control plane clamping plate and the decoupling clamping plate so as to provide bending rigidity. The torsion leaf spring is clamped by the decoupling clamping plate and the support clamping plate so as to provide torsional rigidity. The bending rigidity and the torsional rigidity are mutually decoupled. The support clamping plate is connected with the base. According to the control plane model two-degree-of-freedom supporting mechanism, the bending supporting rigidity and the torsional supporting rigidity are decoupled, as a result, the bending supporting rigidity and the torsional supporting rigidity can be designed separately, and the position and direction of a bending nodal line and the position and direction of a torsional nodal line can be adjusted conveniently.

Description

technical field [0001] The invention relates to the field of aircraft wind tunnel tests and the field of aerospace, in particular to a two-degree-of-freedom support mechanism for a rudder surface model, which can be used to study the aeroelastic characteristics of a rudder surface under two-degree-of-freedom support conditions of bending and torsion. Background technique [0002] There are many aeroelastic problems in the process of aircraft design, and these problems often need to be studied by wind tunnel tests using scaled models that satisfy structural dynamic similarity and aerodynamic similarity. For the aeroelastic problem of the rudder surface, simulating its bending and torsional support stiffness is the key to model design. The main difficulties lie in: [0003] 1) Due to the complex support system of the actual aircraft rudder surface, the bending support stiffness of the scale model is difficult to simulate with a single beam of a specific cross-section, so it is...
