Biotribology and Human Tribology

摘要: In biotribology and human tribology, tribological theories are applied to biological systems interactions, respectively. This chapter focuses on the tribology fields, slip fall accidents hand-object interaction, ocular oral tribology. Slip caused by low friction between shoe floor surface, frequently due a fluid contaminant. Experimental methods of evaluating shoe-floor most relevant slips when mimicking dynamics stepping environmental conditions (using common shoes, floors, and/or contaminants). The mechanisms affecting adhesion, hysteresis, boundary lubrication, hydrodynamic lubrication. Modeling efforts have shown that certain roughness parameters correlate well with friction, adhesion hysteresis can be simulated finite element analysis, models using Reynolds equation simulate effects. Skin is essential for everyday activities such as gripping manipulating objects. outermost layer skin, stratum corneum, modulated hydration allowing body optimize skin through perspiration. Increasing leads improved performance increasing grip strength fine motor speed. interaction in eye, or without contact lens, contributes significantly comfort. Eye discomfort disorder dry eye syndrome occur abnormalities any three tear film layers protect lubricate eye. Low comfort lens. Experiments implicated elastohydrodynamic lubrication may all contribute lens friction. Tooth wear abrasion corrosion major threat healthy teeth dental restorative surfaces.
