AI Technical Summary

Technical Problem

When the rocker arm type main landing gear is loaded with a follow-up load, the general lateral load loading device will cause arching deformation, affecting the structural stability of the original landing gear.

Method used

A rocker arm landing gear follow-up lateral loading device was designed. By combining telescopic loading components and hinge components, and using dummy wheels to fix both ends of the rocker arm dual-wheel landing gear, a combination of yaw, lateral and vertical loading is achieved, providing a safe and stable lateral loading solution.

Benefits of technology

It achieves safe and stable loading of the rocker arm landing gear under multiple angles and attitudes, prevents landing gear deformation, and provides a safe and stable lateral loading effect.

Abstract

This utility model discloses a follow-up lateral loading device for rocker-arm landing gear, relating to the technical field of load testing. The device includes a telescopic loading member, a first hinge member, a second hinge member, a first dummy wheel, a second dummy wheel, and a rocker-arm dual-wheel landing gear. The telescopic loading member includes a first end and a second end. The first end of the telescopic loading member is connected to the first dummy wheel via the first hinge member, and the second end of the telescopic loading member is connected to the second dummy wheel via the second hinge member. The rotation direction supported by the first hinge member is perpendicular to the rotation direction supported by the second hinge member. The first dummy wheel and the second dummy wheel are respectively connected to the two ends of the rocker-arm dual-wheel landing gear. This utility model provides a safe and stable lateral loading scheme when calibrating rocker-arm landing gear using a follow-up load method.
