2) parametrically excited system
参数激励系统
1.
Based on the elastic theory of large deflection and by taking into account the variation of the axial force and its effects on bending deformation of the drillstring in vertical section,the vibration of the drillstring induced by fluctuating weight on bit is described by a parametrically excited system.
