| 摘 要： | 忽略阻尼对钻柱振动的影响,在一维钻杆扭转振动和纵向振动方程的基础上,推导出单根钻杆和多根相同钻杆扭转振动和纵向振动的等效网络.利用等效网络级联理论,结合钻柱系统边界条件,给出了钻柱扭转振动和纵向振动的等效网络和机械等效阻抗表达式,阐述了根据机械等效阻抗确定钻柱扭转振动和纵向振动机械共振频率的原理和方法.由等效网络分析法...

| Abstract: | Ignoring the influence of damping to the vibration of drill strings,the equivalent networks have been given out for a single drill pipe or more of the same drill pipe according to the one-dimensional torsional and longitudinal vibration equation of a drill string.In accordance with the series connection equivalent networks,considering the boundary conditions of the drill string system,the equivalent networks and mechanical equivalent impedance of torsional and longitudinal vibration were derived,and then th... |
