An analysis of linear and nonlinear dynamics rotors is presented taking into account the shear effects. The nonlinearity arises due to consideration large deformations in bending. rotor system studied composed a rigid disk circular shaft. In order study combined effect rotary inertia effects shaft modeled as Timoshenko beam cross section. A mathematical model developed consisting 4th coupled differential equations motion. Method multiple scales used solve these equations. Linear dynamic...
This paper explores analytically the nonlinear dynamic behavior of rotors. Coupled equations motion are formulated using Hamilton’s principle. The rotor model is composed a rigid disk and flexible shaft which characterized as beam circular cross section. Various influences taken into account like effect higher order large deformations, rotary inertia, gyroscopic effect, unbalance axial force. Forced response due to mass presented first for linear analysis then perturbation techniques used...
Abstract Large number of pre-mature failure cases spline half-shafts loader automobile rickshaws were encountered by an industry in Lahore, Pakistan. Unexpected fracture the spline-region reported shortly after shafts put to service. This paper presents findings a systematic investigation that was carried out find root cause failure. Visual inspection, mechanical characterization, microstructural analysis, and chemical composition analysis used study It revealed torsional fatigue nature,...
