The external inspirator is available to drive the resonator to produce traveling wave.Under resonant frequency the distortion of resonator reached a peak.

外激励驱动方式可以使扁环型谐振管产生有效分量，在谐振频率下，谐振管综合变形量最大。

The technique character of the baffle of inspirator was introduced.A feasible process plan was determined and the integral piercing blanking bending forming die was designed.

介绍了挡板零件工艺特点,确定了合理工艺方案,设计1副落料、冲孔、压弯三道工序一次成形模具。
