轴对称矢量喷管运动机构多学科耦合仿真

Multidisciplinary Coupling Simulation of Axial-Symmetric Vectoring Exhaust Nozzle

基于MSC.ADAMS构建了参数化轴对称矢量喷管多体动力学模型,并以AMESim为平台搭建了A8环和A9环控制驱动液压系统模型,模型中应用算法表达了A8环同步机构的力学特性,并考虑A8同步机构效率以及间隙,实现了轴对称矢量喷管机电液一体化的多学科耦合仿真,获得了机构偏转过程中A8环同步机构受载特性,弥补了对A8环同步机构受载特性的认识不足,对类似复杂机构的多学科耦合仿真具有重要的参考价值。

A parameter multi-body dynamics model of axial-symmetric vectoring exhaust nozzle（ AVEN）was built using MSC. ADAMS. Meanwhile,a hydraulic driving system model of A8 and A9 ring was set up based on AMESim platform,and the mechanical characteristics of A8 ring synchronous mechanism were expressed in this model using mathematic algorithms,meanwhile,we consider the efficiency and clearance of A8 ring synchronous mechanism. With the help of coupling simulation of AVEN mechanical electrohydraulic system,the load characteristics of A8 ring synchronous mechanism were gotten. This paper covers the shortage of understanding about the load characteristics of A8 ring synchronous mechanism in recent product developing process,and it also provides a reference for multidisciplinary coupling modeling of complex mechanical electro-hydraulic system.
