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

外激励的驱动方式可以使扁环型管产生有效的行波分量，频率下，管的综合变形量。

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.

绍了呼吸器挡板零件工艺特点,确定了合理的工艺方案,设计1副落料、冲孔、压弯三道工序一次成形的模具。
