Abstract
The finite element model of an aircraft hydraulic pipe was established using the ANSYS APDL command in this paper. The equivalent static pressures as surface loads were applied to the hydraulic pipe based on LS-Dyna software. The pressures were measured in the tire burst test. The stress, strain contours and time course curve of hydraulic pipe were obtained under the dynamic loads. The elastic-plastic deformations of the hydraulic pipe were analyzed by Von Mises yield criterion. The maximum stress is 1090000KPa beyond the yield limit. The hydraulic pipe occurred to plastic deformation. The maximum strain is 0.29168. It is not exceed the elongation of the material. The pipe does not break.
