Description
technical field [0001] The invention belongs to the field of auxiliary positioning tooling for test loading, and in particular relates to a method, device and application for drawing lines on adhesive tape during test loading. Background technique [0002] In the current static / fatigue strength tests of full-scale aircraft structures, the tape-lever system is the main loading form. When using the adhesive tape-lever system for test loading, accurate application of load is the guarantee of loading accuracy and loading accuracy, which will directly affect the test results. [0003] The accurate positioning of the position of the tape on the test piece is one of the basic tasks for the loading accuracy of the tape-lever system, which runs through the whole process of the test. The positioning and line drawing of the adhesive tape on the existing test piece are all done manually by the designer. The specific process is as follows: 1. Use special equipment to draw the long axis ...
