Nonlinear vibration analysis of axially moving strings in thermal environment

摘要: In this study, nonlinear vibration of axially moving strings in thermal environment is investigated. The haracteristics the system such as natural frequencies, time domain response and stability states are studied at different temperatures. velocity axial movement assumed to be constant with minor harmonic variations. It presumed that equilibrium. Using Hamilton’s principle, equation motion, t[1]he boundary conditions derived then solved by applying Multiple Time Scales (MTS) method. effect temperature on characteristics linear stability, critical speeds Considering ideal non-ideal for supports, discussed three excitation frequencies. bifurcation diagrams presented under influence various speeds.
