Regularities of interactions between elements of a spherical contact unit with an antifriction polymeric interlayer

Numerical Analysis of Influence Friction to Parameters Contact Zone of Spherical Bearing

“…На основе анализа результатов экспериментов в качестве модели поведения материала была выбрана и идентифицирована модель деформационной теории упругопластично-сти с упругой объемной сжимаемостью и нелинейной диаграммой ква-зиравновесного деформирования при свободном сжатии с минималь-ной скоростью нагружения. По полученным экспериментальным дан-ным построены модели деформирования контактного узла на примере сферической опорной части с антифрикционной полимерной прослой-кой, а также был произведен предварительный численный анализ ра-боты исследуемых материалов с точки зрения контактного взаимодей-ствия, прочности и надежности [17][18][19].…”

Deformation Behavior Numerical Analysis of the Flat Sliding Layer of the Spherical Bearing with the Lubrication Hole

“…], antifriction [3, 6 and etc. ], thermophysical and other operational properties [5] of the radiation-modified PTFE and composite materials based on it. The modified PTFE advantage in terms of wear resistance, radiation resistance, and elastic properties compared with PTFE-4 is noted in [1,2].…”

“…It was noted that the modified PTFE has an average friction coefficient of significantly less than that of ordinary PTFE-4, with a surface wear rate lower by a couple of orders. Modern antifriction materials are widely used in medicine [7,8], aviation [9], bridge engineering [3,5], industry and other branches of science and technology. Experimentally substantiated effective numerical models describing the polymers behavior, including within the framework of frictional contact, are necessary for their effective use as anti-friction coatings and layers.…”

“…The particular relevance of solving problems associated with transport and logistics systems elements and the problems associated with bridge construction is noted at the moment: geometric configuration and technology of deformation joints [10,11], bearing [3,5,12], bridge spans [ [13] and other elements. The study of the possibility of using modern antifriction polymer materials [12, 14 and etc.…”

“…Such constructions are work within the framework of frictional contact interaction and belong to difficult-to-repair units. Of particular interest to the analysis of the carrying capacity, strength, wear resistance of the bearing elements in general and contact parameters in particular [3,5,15] including the materials from which their elements are made can be noted.…”
