Modelling and analysis of dynamic frictional interactions of vibro-driven capsule systems with viscoelastic property

Abstract: This paper studies the dynamic frictional interactions of the underactuated vibro-driven capsule systems with the viscoelastic property. Frictional dynamics of the capsule systems is an active research domain, while the online implementation and control of the friction models are still intractable tasks. This paper investigates the frictional characteristics of the capsule systems in the dynamic regime, including particularly the non-reversible drooping and hysteresis. Firstly, the frictional interaction dynam… Show more

“…In addition to the above studies, some novel model-based control methods have also been proposed. In [22], they mainly studied the friction characteristics of the capsule system under dynamic conditions, especially the non-reversible drooping and hysteresis. The original intention of this research is because the friction model is still difficult for online implementation and control.…”

“…A dynamic friction force identification method is used based on our previous work [ 49 ]. For further research on dynamic friction identification methods, one can refer to some state-of-the-art works [ 57 , 58 ]. Therefore, in this paper the desired fluid force is where is the estimated friction force, and is the estimated external disturbance.…”

“…One of them is the use of composite materials, which leads to many random structural parameters in the aircraft manufacturing process 13 . Physical properties of structure materials, such as Young's modulus, Poisson's ratio, etc., structural properties or even nonlinearities 14 , 15 can be considered as random factors, which can be represented as random field distribution functions. Due to these factors, the response of structure under excitation will not be linear, but appears as time and field functions of random variables.…”
