利用减轻质量和提高刚度的方法，对抗田机进行了减振研究。在自制了旋转件弯曲振动专用夹具的基础上，根据非电量电测技术，试验求得了坑田机钻头减振设计前后钻尖处的振动状态，验证了减振的有效性 Using the method of reducing the mass and increasing the stiffness, the vibration reduction was carried out against the farm machinery. Based on the self-made bending fixture for rotating parts, the vibration state at the drill tip before and after the vibration damping design of pit machine is obtained by the non-electric measuring technology, which verifies the effectiveness of damping
