| Abstract: | The structural characteristics of lawnmower chassis and difficulties in forming of the part were analyzed. Finite element software Dynaform for sheet forming was used to numerically simulate the technological process; then feasible blank shape was determined and the forming limit diagram for each technological program was obtained. The defects and causes produced under different processing conditions were analyzed in order to guarantee the reliability of each forming process. |
