摘要：
For both military and civil aircrafts are in service, there is always a variation of free play among the joint components of control due to wear. In fact, the variation of free play is an uncertain parameter. In this paper analytical procedure was developed basing on Nastran, which can quantify uncertainties in the complicated swept wing with control surface and gives the quantificational risk information about nonlinear aeroelstic stability in the practice.
