Abstract EN
The nonlinear dynamic responses of a wire rope under periodic excitation in a friction hoisting system are investigated.
Longitudinal excitation experiments of different periodic excitation frequencies are performed.
The nonlinear dynamic characteristics of the rope, including transverse, longitudinal, and coupled vibrations, are discussed with time-frequency analysis.
The results show that the transverse vibration is a forced vibration following the excitation, while the longitudinal vibration shows a complex, random vibration state.
The vibration amplitude and intensity deviate significantly from their linear trend (superharmonic resonance) at some excitation frequencies, and this deviation indicates the typical nonlinear multiorder natural frequency characteristics.
The lifting motion can lead to additional corrugated high-order harmonics and cause a fundamental wave distortion of low-frequency excitation.
Experimental evidence for the coupling characteristics of the transverse-longitudinal rope vibration in the lifting process is found.
