Abstract

The invention belongs to the field of airplane strength test technology research, and particularly relates to a bent plate comprehensive test device which comprises a test piece assembly, a triangularassembly array, an axial and bending loading assembly and a shearing loading assembly. The triangular assembly array comprises triangular assemblies, and floor beam loading triangular assemblies which are used for applying an annular load, a floor beam stretching load, a floor beam compressing load and a floor beam bending load to a test piece; the axial and bending loading assembly comprises a base platform, a fixed end assembly and a movable end assembly and is used for applying an end load to the shearing loading assembly; the shearing loading assembly comprises a bearing frame, a straightedge loading frame and a pull rod assembly and is used for applying shearing force in opposite directions to the two straight edges of the test piece. According to the bent plate comprehensive test device, loads such as stretching/compressing, shearing, air tightness, bending, end shearing and stretching/compressing and bending of the floor beam can be independently applied, combined loading of any load can be conducted, and meanwhile application of all the loads does not interfere with each other.

Description

technical field [0001] The application belongs to the field of aircraft strength test technology research, in particular to a curved plate comprehensive test device. Background technique [0002] The comprehensive strength test of the curved plate mainly studies the static, fatigue and damage tolerance performance of the curved plate of the fuselage, and provides the basis for the design analysis, structural optimization and damage repair of the fuselage panel and other structures. It plays a very important role in pre-study and type verification. [0003] For this reason, all countries in the world are actively developing curved-plate comprehensive test devices. However, the current curved-plate comprehensive test devices have at least the following deficiencies: 1. Coordinated loading at one end of the test piece by multiple hydraulic actuators, while force control and There is a requirement for displacement control, and the control is difficult and risky; in addition, th...
