A Full Spectrum Analysis of a Jeffcott Rotor with Switching Crack in the Presence of Internal and Ex is developed for a Jeffcott rotor considering both external and internal damping, crack force, and unbalance force. The crack in the rotor model is considered as switching crack function in the form of a rectangular shape, which provide forces that generate the forward and backward whirls at variedchiropractor 发表于 2025-3-30 14:12:54

Determination of Local Flexibility Coefficients of a Functionally Graded Shaft with Breathing Crackrchers have calculated SIFs in a cracked beam or rotor made of homogeneous materials, but for functionally graded (FG) materials is scarce. The radially graded FG shaft consists of aluminum oxide (Al.O.) as ceramic constituent and stainless steel (SS) is as metal constituent and properties of materiornithology 发表于 2025-3-31 07:55:16
