| Abstract: | In this paper,the elasticity-plaslickty and large deformation non-linear analysis of a helicopter landing skid has been carried out by using MSC/NASTRAN. The results of calculation is accorded with ones of the static test. The reliability of theoretical analysis method has been proved. |
