Combined experimental and numerical simulation of abrasive wear and its application to a tillage machine component

Numerical and Experimental Analysis of the Abrasive Wear Of Two Steels Used in Tillage Tools

“…The comparative analysis of the mass loss obtained in the simulations for each type of steel showed a tendency to increase in magnitude as the clean (uninterrupted) working time increased, reaching total values of 314.03 and 79.08𝑔, for AISI 1010 and AISI C1064 steel tools, respectively (Figure 5). The trend and values obtained in the simulation were similar to those found by other researchers, either by simulation (Graff, 2010;Rojek, 2014) or experimentation in controlled or field conditions directly (Graff, 2010;Rojek, 2014;Hoormazdi et al, 2018;Chen et al, 2018;Ucgul et al, 2017, Graff, 2010, Bedolla et al, 2018.…”

“…It is generally quantified by measuring the loss of material, and currently experimental (Pérez et al, 2010;López, 2011;González, 2012;Jia y Zhou, 2012;Rojek, 2014;Singh et al, 2017;Obrad et al, 2018;Chen et al, 2018;Bedolla et al, 2018) and numerical methods have been used for its study. Among the numerical ones, the Distinct or Discrete Element Method (DEM) has the most application for the study of abrasive wear (Graff, 2010;Rojek, 2014;Perazzo et al, 2016;Hoormazdi et al, 2018;Chen et al, 2018;Ucgul et al, 2017, Graff, 2010, Bedolla et al, 2018Montes, Herrera, López, Pérez, & Torres, 2023;Zolotarevskiy, Gallo, Pereira, & Barnett, 2022;Zhang, Fu, Ren, Liu, Lin, Zhang & Zhang, 2024). The advantage of the latter over traditional methods is that it allows predicting the behaviour of a given phenomenon, and also decreases the time required for testing.…”

“…The models developed in DEM in the aforementioned research, for the simulation of problems related to geomaterials, take as input data the parameters related to the microstructure of these materials (Graff, 2010;Rojek, 2014;Perazzo et al, 2016;Hoormazdi et al, 2018;Chen et al, 2018). Microstructural parameters, as usual, can be estimated by simulation from macrostructural properties, which are determined by conventional tests performed in soil mechanics laboratories, or from tests performed directly in the field (Pérez et al, 2010;López, 2011;Obrad et al, 2018;Bedolla et al, 2018). The definition of one or the other microstructural parameter depends on the software to be used.…”

Analysis of Wear-Resistant Surface with Pangolin Scale Morphology by DEM Simulation

“…The change law of the wear rates agrees with that of the laboratory results. The wear loss increases with the increase in velocities in a certain range, and decreases when velocity exceeds this value [15]. In some cases, this is because of the increase in the kinetic energy of the pangolin scales, which is discussed in Section 3.1.…”

Proposta De Máquina Para Teste De Desgaste De Ferramentas Agrícolas Em Escala Real Com Reservatório Circular De Solo

“…Um ensaio de laboratório satisfatório para substituir o ensaio de campo deve apresentar mecanismos de desgaste semelhantes aos testes de campo, "INOVAÇÃO TECNOLÓGICA: Os novos rumos da Engenharia Mecânica e Industrial." Anais do XXII CONEMI -Congresso Internacional de Engenharia Mecânica e Industrial| 3 de 20 para possibilitar uma avaliação relativa do comportamento de desgaste do material e relacionar ao desempenho real (Bedolla et al, 2018;Tylczak et al, 1999;Jaramillo et al, 2011) Para recriar as condições das ferramentas de lavoura com menor custo e superar as dificuldades de controle das variações de solo e o tempo limitado de teste impostos pelo setor agrícola, vários pesquisadores desenvolveram testes que utilizam a ferramenta em escala real, submersa em reservatórios com amostra de solos ou outros materiais abrasivos ( Fechete-Tutunaru et al, 2019;Schramm et al, 2019;Tekeste et al, 2022;Zhang e Kushwaha, 1995).…”
