Dr Yinghui Zhang has recently presented a paper "A Multi-asperity Surface Contact Model for the Simulation of Friction in Virtual Environments". This paper presents a new dynamic friction model for haptic rendering of friction in virtual environments. A surface contact model is proposed to efficiently represent the interactions of asperities between contacting surfaces. The simulation results show that the friction model captures most of the friction phenomena observed experimentally. Mathematical methods are also developed to determine the value of parameters by which the friction model is characterized. This parameterization provides a high level user interface and thus makes the model easier to use.
