深孔钻削系统无阻尼动力减振器的参数优化

摘要

根据实际的加工现场，对深孔钻杆附加动力减振器的减振系统进行简化，得到系统的运动方程和有关减振指标；分别研究了钻杆系统处于共振和非共振条件下无阻尼动力减振器的减振特性，从而确定其设计参数，使得在结构设计阶段，通过选取合适的刚度材料，使其在工作过程中减振效果最佳。%According to the actual processing site,the damping system of deep hole drill pipe additional dynamic absorber was simplified,and the motion equations of the system and the damping indicators were gotten.Studying the damping characteristics of dy-namic absorber vibration when the main system was resonant and non-resonant respectively,the design parameters of the undamped dy-namic absorber were determined.Thus,in the stage of structural design,by selecting appropriate stiffness material,the damping effect of the undamped dynamic absorber will be best in work process.
