The effects of crack direction on nonlinear dynamic characteristics are discussed in detail. The results show that:while the external excitation frequency is half of the crack pipe natural frequency, the breathing crack pipes produce obvious super-harmonic resonance.
研究结果表明：当外部激励频率为裂纹结构基频的1／2倍时,呼吸裂纹管发生明显的超谐共振现象,且随着方向角φ的增大,第2谐波分量的幅值不断减小。
