“…Due to the three-stage speed characteristics of the acceleration, constant speed, and deceleration, the tension distribution of the rope can be divided into three stages. e tension at the acceleration stage can be divided into a dynamic tension regime and an inertial tension regime [18]. e transverse vibration is mainly aggravated with the increase in speed.…”

“…Both longitudinal and transverse vibrations can reduce the effective friction between the rope and the pulley surface [17]. In severe cases, the friction is insufficient, and the rope will slip [18,19]. erefore, the study of the rope dynamic response under periodic excitations has an important guiding role in detecting the harmonic excitation response mechanism and suppressing the vibration of the entire friction system.…”

e 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. e nonlinear dynamic characteristics of the rope, including transverse, longitudinal, and coupled vibrations, are discussed with time-frequency analysis. e results show that the transverse vibration is a forced vibration following the excitation, while the longitudinal vibration shows a complex, random vibration state. e 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. e 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.

“…Hertzian contact theory is then applied to calculate both the contact force and friction force, and then the resultant force is obtained. The definition of friction is given in [1], and the dimensional parameters include the Depth, Radius, Angle and contact parameters k, e, and c max . Their specific values are shown in Table 3.…”

“…The friction hoist (Figure 1) relies on the friction force between the rope and the pulley to transport goods or staff. With the development of modern large-scale friction hoisting, the problems of dynamic characteristics, which are not obvious in low-speed and light-load conditions, are gradually reflected, for example, in rope vibration and slippage [1,2]. During dynamic operations, especially in severe conditions such as acceleration and emergency braking, the long-distance suspended rope will produce large elastic vibrations and tension impacts under the influence of the terminal heavy container [3][4][5].…”

A New Transmission Theory of “Global Dynamic Wrap Angle” for Friction Hoist Combining Suspended and Wrapped Wire Rope

A new transmission theory of "global dynamic wrap angle" for friction hoist is proposed. The theory is based on a mine hoist simulation model which combines the suspended rope with the wrapped rope. Rope dynamics in a suspended section are verified by the field experiment results. The theory holds that the mechanical state of wire rope is dynamic through the whole wrap angle, including deformation, contact and friction. When the rope enters the wrap angle, it provides positive friction and changes direction at a certain boundary point. The demarcation of the boundary depends on the rope load on both sides of the friction pulley. The theory is suitable for accurately analyzing the kinetics of high-speed and heavy-load friction hoisting.
