【摘要】 研究裂纹轴在重力作用下,裂纹开闭对裂纹轴刚度变化的影响。通过测量含裂纹的转子轴在垂直方向载荷作用下的刚度变化情况,从而得到转轴跨度中央的垂直方向的挠度随转轴转角的变化规律;采用分度测量仪,得到较准确的转角与挠度的关系,为进一步探讨裂纹转子稳定性与振动相应分析打好基础。更多还原

【Abstract】 Study the influence of crack opening and closing on the stiffness of the crack under the action of gravity. The deflection of the vertical direction of the center of the vertical direction of the vertical direction of the shaft is measured by measuring the vertical direction of the bearing. The relations between the angle and deflection of the angle and deflection are obtained by using the index measuring instrument, which is a good foundation for the further study of the stability and vibration of the cracked rotor.更多还原
