| Abstract: | This paper deals with a finite element calculation of two roll-over protective structures of Dongfanghong-802 tractor.It gives the deformation and stress distribution of the structures under different loads,and analyses the strength and the rigity. A model test is carried out to verify the theoretical calculation. |
