Abstract:

The problem of resonant whirling of propeller-shaft systems is discussed with special emphasis on those factors determining the critical speeds. Several methods for computing the natural whirling frequencies of propellershaft systems are presented and discussed. Among these methods are approximate formulas for the fundamental natural whirling frequency which are suitable for direct application by the shaft designer. Computed and experimentally determined natural frequencies are compared. The possible forced whirling motions due to hydrodynamic forces acting on the propeller are discussed. Author
