一种飞机试验加载杠杆非共线连接装置及其设计方法
By designing a U-shaped force transmission rod and a detachable nut fixing method, the problem of the lever connection point and the loading point not being on the same straight line in a confined space was solved. This enabled reliable connection and application of test loads in a confined space, meeting the requirements of aircraft structural fatigue testing, and improving test efficiency and device maintenance convenience.

AI Technical Summary
In aircraft structural fatigue tests, it is difficult to ensure that the lever connection point and the aircraft loading point are on the same straight line in a confined space. Existing connection methods are limited and cannot meet the test requirements.
A non-collinear connection device for loading levers in aircraft testing is designed. By changing the force transmission rod of the connection joint to a U-shaped cross-section, the force transmission rod is vertically inserted into the force transmission hole and fixed with a detachable nut. Combined with a spherical bearing and a polyurethane block, the reliability and flexibility of the connection are ensured.
It enables the application of test force loads in confined spaces, has a reliable connection method, is easy to install, meets the requirements of aircraft structural fatigue testing, and improves test efficiency and device maintenance convenience.
