In order to clarify the fatigue characteristics of the rigid rocker arm of the aero-engine and meet the requirements of the rigid rocker arm during actual operation, a rigid rocker fatigue test bench of the VSV mechanism was designed based on a certain aero-engine. In order to simulate the actual working conditions, the equivalent aerodynamic load was applied to the equivalent blade by the loading device. The stroke of the actuator was controlled by PID and operated according to the preset stroke-time curve. The rigid rocker arm was subjected to
