The invention belongs to the field of aviation test application, and particularly relates to an aiming positioning device and method for a strong impact test system. The device comprises a positioning flange 1, a positioning ring 2, a core shaft 3 and an infrared generator 7, wherein a gun barrel is provided with a containing cavity, the positioning flange 1 is coaxially mounted in the containing cavity of the gun barrel, the positioning ring 2 is fixedly mounted on the positioning flange 1 through a fastening screw 4, the core shaft 3 is nested in the positioning ring 2 and is fixedly connected with the positioning ring 2 through a positioning pin 5, and the infrared generator 7 is coaxially mounted at the end part of the core shaft 3. According to the invention, the device is installed in a gun barrel, the coaxiality with the axis of the gun barrel is guaranteed through flanges at the two ends, non-contact aiming and positioning are conducted through light beams of an infrared generator installed in the center, installation and positioning of an impacted object are achieved, the purpose of guaranteeing coincidence of a test piece and a tested point is achieved, installation is convenient, the installation time is saved, and efficiency is improved.
Description
technical field [0001] The application belongs to the application field of aviation test, and in particular relates to an aiming and positioning device and method for a strong impact test system. Background technique [0002] The strong impact test system is a test system used for strong impact and extreme target tests on the test piece, which can verify the safety, reliability and effectiveness of the test piece. In the impact test, the corresponding positioning structure is generally used to position the test piece to avoid the deviation of the test piece during the impact test. However, in the ultimate target test, there is still a lack of an aiming and positioning method that can achieve the coincidence of the axis of the test piece with the point to be tested. The test piece cannot be accurately aimed at the object being hit, so that the accurate test of the performance of the test piece cannot be realized. [0003] Therefore, it is desirable to have a technical soluti...
