The number of main landing gear for multi-wheels and multi-struts landing gear aircraft is large, and the test machine and test equipment are heavy. When the test is unloaded, the uncoordinated release of energy is easy to generate a large impact load on the support point structure, and the load is uncontrollable, which affects the assessment of the test. A load limited technology was designed,in which the aircraft test support and loading functions were taken into account. The principle, structure and functions of the technology were elaborated. By modifying and combining existing equipment, a verification platform was built to verify the working principle of the load limited technology. The verification results show that the principle of the technology can fully meet the test requirements.
