| 英文摘要: |
| The aim of this study was to investigate the feasibility study of the cover of automobile crankshaft machining process. According to the characteristics of the part, parts were assembled by machining process combined with multi pass drawing with shaping, and the numerical simulation of forming process was analyzed by the finite element technology. Fi- nally, the feasibility of process was verified using physical experiments. The surface quality of the trial is good, the size precision of the trapezoidal bulge at the inner edge of the flange meet the requirements, which was consistent with the finite element simulation results. The automobile crankshaft cover board processed by multi-pass drawing and plastic composite technology can fully meet the requirements of the actual use , and the forming process is effective and feasible. |
