The actual aircraft hydraulic pipes are illustrated as the object of study,the finite element mode of pipes are established by the means of hexahedron solid element,and caculating the pipes dynamic responses through true engine cabin load、aircraft pipes limit work pressure pulse and pipes pressure fluctuation. And then the effect of clamp on aircraft hydraulic pipeline dynamic stress is studied. It achieves better consistency through comparing the calculation results and the clamp applying principle that put forward by《GJB 3054- 97 aircraft hydraulic system design,installation requirements》. What' s more,this paper put forward clamp configuration principle about bend pipe,the studying resules can provide basis for clamp optimization configuration in pipelines vibration inhibition technology.
