英文摘要: |
For the phenomenon of particularity and diversity of mandrel structure which resulting in its non-uniqueness of
simulation modeling at the pipe bending process. the mechanism of mandrel structure was discussed. and three models
such as rigid ball hinge, rigid pin hinge, super-elastic connecting were proposed; According to the simulation effects of
different models with same mandrel, it was proposed that different mandrel models should be used depending on the
research object; The results show that the strategy can help improve simulation efficiency, avoid blindness of simulation
modeling, and beneficial to have specific research with different requirements. |
