依据极坚硬岩石条件下冲击凿岩钎具的能量传递模型,采用梁单元及预应力假设,利用 ANSYS 有限元软件对超长重型凿岩钎杆上做了动力谐响应分析,得到了各阶模态振动频率和位移、力对频率的响应曲线。
According to the energy transfer model of impact rock drill under very hard rock conditions, the beam unit and prestressing assumption were used to analyze the dynamic harmonic response of the long heavy rock drill rod with ANSYS finite element software. State vibration frequency and displacement, force versus frequency response curve.
