A fractional order friction model

ISA Transactions, 2023
A new dynamic model for friction is proposed based on the commonality between frictional order dynamics and friction behavior. The model can achieve accurate modeling both in the sliding and the pre-sliding region with fewer parameters. Simulation results of the FOFM are illustrated with the parameters identification using the particle swarm ...

Adaptive friction compensation with time-delay friction model

Proceedings of the 4th World Congress on Intelligent Control and Automation (Cat. No.02EX527), 2003
This paper presents a new compensation technique for a time-delay friction model that captures the effect of frictional memory. The proposed control utilizes a proportional-derivative (PD) control structure and an adaptive estimate of the friction force.

Boundary friction model in punch friction test

Journal of Materials Processing Technology, 1994
Abstract A boundary friction model which includes both plowing and adhesion stress has been developed to simulate the stretching of sheet over a cylindrical pin boundary regime. The equilibrium equation defining the local frictional shear stress on the workpiece has been combined with the existing friction model to determine fractional contact area ...
