Abstract��To ensure the quality of the feedback cable in aero engine nozzle�� the strength of the nozzle feedback cable should be tested before use. According to the requirements of relevant technical standards�� through technical research�� a special fixture for locking steel cables was developed�� and the strength testing for the breaking force of steel cables and the two ends�� axial force of the steel cables was carried out by selecting reasonable test parameters. The results showed that there was no slip and stress concentration during the tensile process of the cable�� and the cable was broken in the effective part. At the same time�� the coaxiality was guaranteed. The experimental data obtained by this method met the technical requirements�� can reflect the strength index of the steel cable under the actual working conditions�� provide the experimental basis for the design department�� meet the testing requirements of raw materials and products�� and fill the test blank in the laboratory.
