An Integrated Approach for Friction and Wear Simulation of Tire Tread Rubber. Part II: Wear Test, Characterization, and Modeling
Authors: Li Zhao , Li Ziran , Wang Yang 
Published: July 2019

ABSTRACT:
On the basis of Part I, Part II continues further research on the wear of tire tread rubber. A test scheme composed of various combined conditions that are widely ranged in energy dissipation is developed. The wear rate and temperature increase are described by exponential energetic models. Coupled with the unified friction model, a well-demonstrated wearing simulation of the rubber wheel is proposed. The wear rate for the rolling of axisymmetric structure is derived, and a nonequal wear increment is proposed according to the maximum allowable wear depth of the surface elements, which act as a criterion for calculating the increment size. In order to maintain high quality of the worn mesh, the boundary displacement method is employed to reposition the interior nodes of the finite element model as well as the surface elements. The computed wear rates are roughly in agreement with the test results. As a further illustration, the tread wear simulation of an axisymmetric tire containing only longitudinal grooves is conducted. For the first time, the evolution rules of wear contour of the axisymmetric tire are revealed, and the linear variation of worn mass with the rolling distance is consistent with the experimental results reported in literature.

Published: July 2019

O presente artigo é recorte de uma pesquisa de mestrado acadêmico, o qual tem como propositiva compreender os desafios do processo de gestão de um polo de EaD do Sistema Universidade Aberta do Brasil (UAB), com vistas a efetivar a educação superior a distância no Oeste do Pará. A metodologia construiu-se por intermédio de um estudo de caso, com abordagem qualitativa e pesquisa documental, bibliográfica e empírica. Utilizou-se para produção dos dados as técnicas da análise de documentos, da observação não-participante e do questionário, organizados com aporte da análise de conteúdo e da triangulação de métodos. Fundamentado no entendimento que a EaD tem oportunizado ingresso ao ensino superior a um número cada vez maior de pessoas, e dos desafios à gestão de um polo de EaD, vivenciados pelos coordenadores que atuam no âmbito do Sistema UAB, os resultados encontrados sugerem que gerir um polo da UAB no interior da Amazônia paraense tem demandado desafios diversos àqueles que coordenam esta modalidade de ensino, dentre eles a evasão, que pode ser decorrente de fatores relacionados ao desconheciento dos estudantes quanto as NTIC, bem como a fragilidade da formação dos tutores presenciais para atuar com esta modalidade de ensino. Assim, concluir-se que a infra-estrutura física, tecnológica e de recursos humanos do polo estudado atende ao proposto em sua implantação, ainda que hajam desafios a serem superados pelos gestores de polo e IES ofertante, a fim de garantir uma educação superior de qualidade para o interior da Amazônia brasileira.

Authors: Rosidin Udin , Eriyani Theresia , Sumarna Umar 
Published: July 2019

Pelaksanaan PHBS sebagai awal terbentuknya RW sehat adalah semua perilaku yang dilakukan atas kesadaran sendiri sehingga dapat menolong dirinya sendiri di bidang kesehatan dan berperan aktif dalam kegiatan-kegiatan kesehatan. Cakupan rumah tangga berperilaku hidup bersih dan sehat di Jawa Barat berdasarkan data yang diperoleh dari profil data kesehatan Indonesia tahun 2014 yang dikeluarkan oleh Kementerian Kesehatan sebesar 51,40 %, dari 3.178.032 rumah tangga yang dipantau (Kemenkes RI, 2014). Posisi Jawa Barat berada pada nomor 12 dari 33 provinsi di Indonesia. Apabila kita amati angka tersebut ternyata angka jumlah rumah tangga di Jawa Barat yang melaksanakan PHBS jumlahnya dibawah angka nasional (56,58 %). Belum dilaksanakannya PHBS pada masyarakat Garut salah satunya ditentukan oleh rendahnya pengetahuan masyarakat tentang PHBS. Upaya peningkatan pengetahuan tersebut perlu dilakukan melalui berbagai cara salah satunya pelatihan kader kesehatan. Tujuan kegiatan ini adalah untuk peningkatan pengetahuan kader kesehatan dalam memahami PHBS Rumah Tangga sebagai awal terbentuknya RW sehat. Metoda pelaksanaan Program Pengabdian Masyarakat ini adalah pelatihan kader kesehatan tentang PHBS melalui sosialisasi RW sehat dengan jumlah kader yang hadir sebanyak 25 orang. Kegiatan dimulai dari tahapan perencanaan, pelaksanaan, evaluasi, hingga penyusunan laporan. Hasil kegiatan berdasarkan uji analisis wilcoxon ada perubahan signifikan dalam pengetahuan (Z--4.298) dengan rata pre test 46,2 (SD.8,57)) dan post test 67.3 (SD 9,59). Kesimpulan. Pelaksanaan kegiatan mendapat apresiasi dari seluruh kader kesehatan dan aparat pemerintah yang hadir. Kata kunci : Pelatihan, kader kesehatan, PHBS, RW Sehat.

On composite formulas for mathematical expectation of functionals of solution of the Ito equation in Hilbert space
Authors: Egorov A. D. 
Published: July 2019

This article is devoted to constructing composite approximate formulas for calculation of mathematical expectation of nonlinear functionals of solution of the linear Ito equation in Hilbert space with additive noise. As the leading process, the Wiener process taking values in Hilbert space is examined. The formulas are a sum of the approximations of the nonlinear functionals obtained by expanding the leading random process into a series of independent Gaussian random variables and correcting approximating functional quadrature formulas that ensure an approximate accuracy of compound formulas for third-order polynomials. As a test example, the application of the obtained formulas to the case of a one-dimensional wave equation with a leading Wiener process indexed by spatial and temporal variables is considered. This article continues the research begun in [1].The problem is motivated by the necessity to calculate the nonlinear functionals of solution of stochastic partial differential equations. Approximate evaluation of mathematical expectation of stochastic equations with a leading random process indexed only by the time variable is considered in [2–11]. Stochastic partial equations in various interpretations are considered [12–16]. The present article uses the approach given in [12].
Ways for detection of the exact number of limit cycles of autonomous systems on the cylinder
Authors: Hryn A. A. , Rudzevich S. V. 
Published: July 2019

For real autonomous systems of differential equations with continuously differentiable right-hand sides, the problem of detecting the exact number and localization of the second-kind limit cycles on the cylinder is considered. To solve this problem in the absence of equilibria of the system on the cylinder, we have developed our previously proposed ways consisting in a sequential two-step application of the Dulac – Cherkas test or the Dulac test. Additionally, a new way has been worked out using the generalization of the Dulac – Cherkas or Dulac test at the second step, where the requirement of constant sign for divergence is replaced by the transversality condition of the curves on which the divergence vanishes. With the help of the developed ways, closed transversal curves are found that divide the cylinder into subdomains surrounding it, in each of which the system has exactly one second-kind limit cycle.The practical efficiency of the mentioned ways is demonstrated by the example of a pendulum-type system, for which, in the absence of equilibria, the existence of exactly three second-kind limit cycles on the entire phase cylinder is proved.
Inﬂuence of the chemical structure of cation surfactants on the wetting process of rock-forming minerals
Authors: Opanasenko O. N. , Krutko N. P. , Zhigalova O. L. , Luksha O. V. 
Published: July 2019

Interfacial interactions of cationic surfactants of various chemical structures at the solution / finely dispersed mineral material (quartz and dolomite) interface were studied. It is established that the modification of the surfaces of quartz and dolomite with cationic surfactants leads to a change in the structure and radius of the capillaries due to the formation of adsorption-solvate shells. The hydrophobic ability of cationic surfactants is determined by the structure of the hydrophilic part of their molecules – the balance of amino groups in the alkyl chains and the absence of steric hindrances during adsorption interaction with the surface of mineral materials. The mixture of surfactants containing six amino groups and a polyhydric alcohol glycerin has an effective hydrophobic ability from both aqueous and highly mineralized solutions.
