The invention belongs to the technical field of structural mechanism strength and function test load simulation, and particularly relates to a posture and pressure controllable hammer type air bag loading system. The system comprises a hammer type air bag loading unit, an air pressure controller, a posture control mechanism and a load controller. An air bag shape limiting box is provided with an opening in one end and a mounting hole in the other end thereof; an air bag is arranged in the air bag shape limiting box and is provided with a loading surface exposed from the opening of the air bag shape limiting box; a posture control handle is connected with the mounting hole of the air bag shape limiting box; an air valve is installed on the air bag shape limiting box and connected with the air bag in the air bag shape limiting box. a compressed air pipe is connected with the valve; the air pressure controller is connected with the hammer type air bag loading unit through the compressed air pipe; the posture control mechanism is connected with the posture control handle of the hammer type air bag loading unit; and the load controller is connected with the air pressure controller and the posture control mechanism. The original appearance of the deformable structure is protected, and meanwhile the test load simulation precision is guaranteed.
Description
technical field [0001] The application belongs to the technical field of structural mechanism strength and function test load simulation, and in particular relates to a hammer airbag loading system with controllable attitude and pressure. Background technique [0002] During the design and development process of the mechanical structure / mechanism, it is necessary to verify its strength and function through strength and function tests. During the test, it is necessary to use technical means to apply the design load to the mechanical structure / mechanism, which is the load simulation technology. , load simulation technology is the key technology in these tests. Especially for the deformable structures / mechanisms that have appeared in recent years, the load simulation technology has become a technical difficulty in the tests of these deformable structures / mechanisms. The outer surface configuration of the new deformable structure can produce controllable repeated deformation ac...
