摘要
通过对阶梯式弯曲振动镗刀杆的理论分析,推导出了圆形截面和矩形截面组合的阶梯弯曲振动镗刀杆的频率方程,并对阶梯弯曲振动镗刀杆进行了试验研究。结果证明所推导的频率方程是正确的和实用的。
Based on theoretical analysis of stepped bending vibration boring bars,the frequency equation of a stepped bending vibration boring bar with circular and square sections is established.Experimental study has proved the correctness and practicabiity of the frequency equation.
