A test device for an aircraft suspension structure
By coordinating the design of the arc-shaped carriage and drive components, combined with the overload shear safety pin and segmented protective sleeve, the problem that existing test devices cannot simulate the full working conditions of fire-fighting helicopters has been solved, and precise performance testing and safety testing of the suspension structure have been achieved.

AI Technical Summary
Existing aircraft sling structure testing equipment cannot accurately reproduce the full-condition load of firefighting helicopters during static hovering and dynamic maneuvering, resulting in distorted test results and failing to effectively verify the comprehensive performance of the sling structure.
A test device was designed, comprising an arc-shaped carriage, a slider, and a drive component. Through the synergistic effect of the slider and the drive component, the static hovering and dynamic maneuvering conditions of a fire-fighting helicopter were simulated. The load-bearing belt was fractured at a fixed point by the linkage of the overload shear safety pin, the drive plate, and the cutter, and key data were collected. At the same time, protective components and segmented sheath design were adopted to suppress the high-speed rebound after the load-bearing belt fractured.
It enables accurate performance testing of the suspended structure under all working conditions, provides real and effective data support, improves design reliability, ensures test safety, and avoids equipment damage and personnel injury.
