| Abstract: | The reactions to the work implement of an excavator during work are all transferred to the front frame.Aiming at the fractures at the upper juncture of the vehicle frame,the problems of stress concentration and structure defects are removed by CAE analysis during design.The analysis methods are discussed.To design the frame scientifically,the intensity analysis of certain design structure is made,and then the improvements are put forward. |
