Based on the Absolute Nodal Coordinate Formulation (ANCF) method and the NURBS expression algorithm of friction, a rigid-flexible coupling dynamics model of a complex adjusting mechanism of Variable Stator Vane (VSV) is built, taking into account factors such as the assembly clearances, dimensional tolerances, flexibility of key components, thermal aerodynamic load, and contact friction. According to the parametric representation and the spatial distribution relationship among the components, a rapid automatic modeling process of multibody dynamics for the VSV adjusting mechanism is developed, considerably improving the modeling efficiency. The simulation results of the single-stage experiment cases with emulated thermal aerodynamic loads and the multiple-stage joint commissioning experiment cases with thermal aerodynamic loads of the VSV adjusting mechanism show that the multibody dynamics model has high reliability in the simulation of the blocking force. The friction torque induced by the force components of the aerodynamic load is the main cause of the blocking force, the retardation of the adjustment angle and the reduction of adjustment accuracy of the VSV mechanism. The influence of the torque components of the aerodynamic load on the blocking force and the retardation of the adjustment angle is not obvious. Despite its little effect on the blocking force, the flexibility of the key component is an intrinsic factor that reduces the adjustment accuracy.
