Problems solved by technology
[0003] The rudder core of the air rudder is generally welded in the form of the rudder core skeleton and the rudder core skin, and the rudder core is generally made of titanium alloy; when the aircraft flies in the atmosphere, affected by "aerodynamic heating", the temperature of the aerodynamic rudder will increase. Therefore, the metal rudder core is covered with a heat-resistant jacket. The heat-resistant jacket is generally made of composite materials with high temperature resistance, ablation resistance, erosion resistance, and thermal shock resistance. Composite materials are relatively brittle, so Before the preparation of the air rudder heat shield, it is very necessary to test the stimulated structural strength and deformation of the air rudder rudder core, so as to avoid unnecessary damage to the heat shield layer caused by the air rudder core under the air rudder flight excitation state. damage, less attention has been paid to this issue in the prior art

Embodiment 1
[0030] figure 1 It is the rudder core skeleton 32 of the air rudder, the rudder core skin 33 and the rudder core with the rudder shaft 34. figure 2 It is an air rudder rudder core excitation testing device of the present invention.
[0031] The present invention adopts following technical means to realize:
[0032] Air rudder rudder core excitation test device includes: test bench 1 and tooling 2 for clamping air rudder rudder shaft 34, tooling 2 consists of two clamping assemblies 26 with identical structures, a double-ended stud 23 and 6 The clamping assembly 26 is a cuboid structure with a through-slot on one side. When the two clamping assemblies 26 are combined together, a cuboid is formed. The two through-slots on the sides of the two clamping assemblies 26 are combined. form a cylinder or truncated cone hole 21 that completely matches the size of the air rudder rudder shaft (the rudder shaft 34 may be in the shape of a cylinder or a truncated cone), and the cylindric...

The invention provides an air rudder core excitation test device. An air rudder core special test tool is adopted, an air rudder core is arranged on a test workbench, a strain gauge and a displacementsensor are arranged on the air rudder core or at the periphery, when a vibration exciter on the test workbench applies an excitation effect on the air rudder core, the strain gauge arranged on the air rudder and the displacement sensor arranged at the periphery test the strain of the air rudder core and the integral deformation, and reliable support is provided for the design and the subsequent process of the air rudder core.
Description
technical field [0001] The invention relates to an air rudder rudder core excitation test device, in particular to an air rudder rudder core excitation test device capable of changing the position of an excitation force, and belongs to the technical field of mechanical component testing. Background technique [0002] The air rudder is the control and execution mechanism of the flight path of the aircraft. By changing the angle of the air rudder during the flight, the aircraft can be lifted, pitched or yawed. The aerodynamic shape of the air rudder directly affects the control accuracy of the aircraft, and is an important part of the aircraft. [0003] The rudder core of the air rudder is generally welded in the form of the rudder core skeleton and the rudder core skin, and the rudder core is generally made of titanium alloy; when the aircraft flies in the atmosphere, affected by "aerodynamic heating", the temperature of the aerodynamic rudder will increase. Therefore, the m...
