  • The crucial parts of axial-symmetric vectoring exhaust nozzle(AVEN) were meshed into flexible bodies with solid-shell elements.A flexible multi-body dynamics model of AVEN was built based on MSC.ADAMS command batch processing technique and tree-shape parametric technique.A part of contact constraints in the dynamics model were simplified with point-curve constraints to reduce the computational size.By means of simulation of shaking and swinging movement of the AVEN on normal temperature condition,the loading and dynamic characteristics of the mechanism were achieved.Provided an important reference for virtual design and virtual experiment of AVEN.
