“…With the continuous application of virtual simulation technology in the study of the creeping phenomenon, different types of friction models [15][16][17][18] have been established and verified by the simulation. A two-degree-of-freedom mathematical model [19] was used in an earlier study to simulate the stick-slip motion of the guide moving and agreed with the experimental results. A dynamic model of the creeping phenomenon of the feed system based on the LuGre model [20] was established, and the state of motion of the creeping was obtained through simulation analysis.…”

A mathematical model of the creeping phenomenon based on the mechanical model of the linear feed system was established. The dynamic characteristic parameters of each fixed joint were obtained by Yoshimura’s integral. Using the method, only the dynamic characteristic parameters of the joint surface per unit area with simple structure need to be studied, and then, the dynamic characteristic parameters of the whole joint surface can be obtained by integration. Based on the principle of the half-power bandwidth method and the frequency response function identification, the dynamic parameters of each moving joint were solved by the method of experimental modal analysis. Through the parameters of the fixed and moving joints, a rigid body model of the feed system and a flexible body model including the power transmission parts (ball screw pair) and the motion guide parts (guide slide pair and rolling bearing) were, respectively, established. And then, a rigid-flexible coupling dynamic model of the feed system was obtained through the constraint relationships between joints. The influence of both the external load and the feed rate on the fluctuation of motion speed of the system was analyzed from this model. The difference between the experimental results and the simulation results on a feed system platform is not greater than 10%, which verifies the creeping phenomenon. This conclusion can provide a basis for the optimization of the dynamic performance of the ball screw linear-feeding workbench.

“…When the feed system is moving, different feed rates and loads can influence the mechanical power to influence the motor power and accuracy. This study will establish the optimum intervals of different feed rates and loads for oil supply timing to avoid excessive oil supply for feed system lubrication, reducing the accuracy, or undersupply burning the guideway that shortens the component lifetime [ 26 , 27 ].…”

“…Other than the properties of frictional surfaces, several parameters are adjusted to control the occurrence of stick-slip motion: tangential stiffness, velocity and contact pressure (Rice and Ruina, 1983). How to eliminate the damage to the brake structure and hazardous noise strongly depends on predicting the critical values of these parameters, where transitions between periodic stick-slip, chaos and stable sliding occur (Bouissou et al, 1998;Bilkay and Anlagan, 2004;Braun and Roder, 2002). The noise and vibration from the brake-disk system may be the most sensible phenomena caused by the stick-slip motion in our daily life.…”

Purpose A dynamic model of the brake system considering the tangential and radial motion of the pad, and the torsion and wobbling motion of the disk is established in this paper. The influence of radial stiffness on the brake system is investigated under different tribological conditions. This paper aims to prove that sufficient radial stiffness is indispensable in the design of the brake system with good tribological performance. Design/methodology/approach By using the lumped mass method, a dynamic model of the brake system is established. A Stribeck-type friction model is applied to this model to correlate the frictional velocity, pressure and friction force. The stability of pad vibration is analysed by analysis methods. A new stability evaluation parameter is proposed to study the influence of radial stiffness on stability of pad vibration in a certain friction coefficient brake pressure range. Findings The findings show that the tangential vibration of the pad transits from periodic motion to quasi-periodic motion under a low tangential stiffness. The influence of radial stiffness on motion stability is stronger under a low nominal brake radius. The stability of the brake system can be ensured when the brake radius and radial stiffness are sufficient. Originality/value The influence of tangential stiffness of pad on stability of the brake system has been researched for decades. The insufficiency of stiffness in radial direction may also generate certain levels of instabilities but has not been fully investigated by modelling approach. This paper reveals that this parameter is also strongly correlated to nonlinear vibration of the brake pad.
