| 摘 要： | 为了去除软磁铁氧体毛刺且不损伤工件,设计了一种复合高斯变幅杆。介绍了超声波去毛刺的原理。将超声波去毛刺的振动过程近似为由两根劲度系数不同的弹簧组成的质点弹簧系统受迫振动模型,得到毛刺断裂条件,以此计算复合高斯变幅杆的最小放大倍数,经理论计算,在满足最小放大倍数的条件下,高斯变幅杆的形状因数比指数杆高40%,大大改善应力集中问题。最后,通过有限元分析验证了上述设计过程的正确性。 |

| Abstract: | In order to clear up the burrs on soft magnetic ferrite without damaging the work-pieces, an ultrasonic horn was designed.Ultrasonic de-burring process was simplified into a particle spring forced vibration system composed of two springs with different stiffness coefficient.The minimum magnification of complex Gaussian horn was calculated after the failure condition was obtained.After calculating, the shape factor of complex Gaussian horn was proved 40% higher than the Exponent horn in the condition of minimum magnification, significantly decreased the stress concentration.The design process was verified by comparing the results of theoretical calculating with the finite element analyzing. |
