Problems solved by technology
Therefore, the whole system has a total of 18 load components. If the load is applied according to the original load components, the number of actuators that need to be applied will be very large, which will increase the difficulty of the tooling of the actuators on the test site.
Moreover, compared to the range of the actuator, the missile and wind loads are relatively small, and the application of small loads with a large range of actuators often cannot reach a satisfactory level of loading accuracy.

The invention provides a device for simulating the connection strength reliability of an airborne missile, which belongs to the technical field of antenna measurement. The device includes: a dummy bomb, used for simulating a missile and a launching device; a hanger, used for fixing the dummy bomb; A loading point is arranged on the hanger and the dummy bullet, and the bending moment of the hanger and the dummy bullet in three orthogonal directions is adjusted by changing the position of the loading point; actuation A device for applying a load to the loading point; a load sensor for measuring the magnitude of the load applied by the actuator. The device provided by the present invention can utilize six actuators to apply six unidirectional loads, and the bending moment on each direction on the test piece can be realized by adjusting the position of the loading point, and the use of pulley guides and front sensors can facilitate the actuator. Install and ensure loading accuracy.
Description
technical field [0001] The invention belongs to the technical field of static testing equipment, and in particular relates to a device and method for simulating the connection strength reliability of airborne missiles. Background technique [0002] During the flight of the aircraft with bombs, the missile and the launching device are connected with the aircraft through the pylon. The strength and stiffness reliability of its connection is of great significance to the flight safety and combat effectiveness of the aircraft. Due to the action of its own inertial load and wind load, stress and deformation will inevitably occur between the missile launcher and the pylon, and between the pylon and the aircraft. Therefore, it is necessary to verify the reliability of its connection strength through ground test testing. To assess whether the connection strength meets the design requirements under various working conditions within the entire flight envelope of the aircraft. [000...
