Axisymmetric Vectoring Exhaust Nozzle (AVEN) of aero-engine undergoes deformation of its roller skeleton components due to thermal aerodynamic load, resulting in component jamming, increasing wear, and reducing lifespan. In order to simulate the working condition of the roller skeleton in the actual AVEN, a roller skeleton principle level experimental system is de-signed and constructed, and wear and friction force experiments are con-ducted. The experimental results indicate that: In room temperature experiments, when the simulated aerodynamic load is light, in some experiments, the roller experienced jamming phenomenon, and even adhesion between the roller and the bushing, causing the motion relationship between the roll-er and the skeleton to change from rolling to sliding, resulting in severe wear of the roller skeleton component, when the simulated aerodynamic load is heavy, the roller undergoes plastic deformation; In the heating experiments, it is found that an increase in thermal load would lead to an increase in the friction force of the roller skeleton component.
