英文摘要：

This paper introduces a deformation mechanism for unmanned aerial vehicle（UAV） with variable forward-swept wing.A mathematical model of the deformation mechanism was established,parameters of which were optimized in matlab software and reasonable structure dimensions were gotten.Using Solidworks and Adams software established the kinematics simulation model,carried on kinematics simulation to the mechanism,obtained motion curves,and carried on the movement analysis.The results demonstrate that the mechanism can meet the requirement of deformation,rotate smoothly and uniformly during the deformation process,and be used as UAV with variable forward-swept wing deformation of institutional programs.
