Abstract

The invention belongs to the field of auxiliary positioning tools for test loading, and particularly relates to an integral tension-compression pad curved surface line drawing plate, a design method and a using method. The design method comprises the steps that firstly, equal-thickness stretching is conducted on an aircraft surface skin in a loading point area to obtain a line drawing plate main body, and the line drawing plate main body is shaped according to the boundary of a tension-compression pad; secondly, a first groove is formed in the line drawing plate main body according to the shape of the tension-compression pad; thirdly, a second groove used for positioning is formed in the line drawing plate main body; fourthly, a third groove is formed in the outer surface of the line drawing plate main body and used for marking the number of the line drawing plate; fifthly, a fourth groove is formed in one end of the line drawing plate main body and used for marking the pasting direction of the line drawing plate; sixthly, after the line drawing plate is designed according to the first step to the fifth step, the line drawing plate is machined.

Description

technical field [0001] The application belongs to the field of auxiliary positioning tooling for test loading, and in particular relates to an integral tension and pressure pad curved line drawing board, a design method and a use method. Background technique [0002] The tension and pressure pad lever system is one of the main loading methods in static / fatigue tests of aircraft structures. In the test preparation stage, it is necessary to paste tension and compression pads on the surface of the aircraft for test loading. Before pasting the tension and pressure pads on the surface of the aircraft, it is necessary to draw a frame line with the same width as the tension and pressure pads on the surface of the test piece according to the benchmarks such as beams, ribs and frame positions, as the basis for pasting and positioning the tension and pressure pads. Therefore, the line drawn on the tension and pressure pad directly affects the accuracy of the sticking position of the ...
