| Abstract: | The external load born by the U-shape frame is analyzed under normal load condition.A finite element analysis model is established.The distributions of the structural stresses and deformations are obtained.The results show that the dangerous section lies at the front bending part of U-shape frame.This provides a design basis for the structure optimization of the U-shape frame. |

| Keywords: | bulldozer U-shape frame finite element method |
