Hoje finalizei a última campanha de ensaios de atrito com discos de borracha contra uma roda de corundum, utilizando areia como contaminante no contato.

Foram 20 te**es experimentais, variando velocidade de deslizamento e fluxo de areia, com o objetivo de entender como contaminantes sólidos alteram os mecanismos de atrito e desgaste em elastômeros.

Esses ensaios conectam diretamente a prática experimental com o que a literatura descreve há décadas:

• a transição entre adesão e histerese,
• a influência da velocidade no regime viscoelástico,
• e o papel crítico dos terceiros corpos, como a areia, na redução de contato real e aumento do desgaste abrasivo.

Agora começa a fase mais silenciosa (e igualmente importante): tratamento de dados, análise e comparação com os modelos clássicos de atrito em borracha.
Pesquisa é isso: medir, questionar, repetir — até entender.

Today I completed the final campaign of friction tests using rubber disks sliding against a corundum wheel, with sand introduced as a third-body contaminant in the contact.

The campaign included 20 experimental runs, varying sliding velocity and sand flow rate, with the goal of understanding how solid contaminants alter friction and wear mechanisms in elastomers.

These tests directly connect experimental evidence with what decades of literature describe:

• the transition between adhesion and hysteresis,
• the role of sliding velocity in viscoelastic regimes,
• and the critical impact of third bodies in reducing real contact area and promoting abrasive wear.

Now comes a quieter — and equally important — phase: data processing, analysis, and comparison with classical rubber friction models.
Research is exactly this: measure, question, repeat — until it makes sense.

Exploring the effects of sand contamination on rubber rolling contacts.

A three body contact increases the complexity of the rubber friction phenomena since it provides an unpredictable effect, it can raise or it can reduce friction.

Another test day. Today I'm investigating rubber friction and wear when the contact is contaminated with sand or some dirt.

This is a very common situation in automotive tires since roads are not fully clean.

Ja descobri algumas funcionalidades do meu perfil no tiktok (). La compartilho as lives dos meus vídeos de estudo que vai para o YouTube.

This was interesting. It started with great expectations regarding the tribology test that was planned to do. Now, my rubber samples were worn by a rough grind stone. However , this time we introduced a contaminant, 250 micron sand particles.

I'm still working on data analysis, but the main point is the small event at the beginning of the test. After the laboratory technician required the operation parameters, I informed him of a slightly higher velocity than usual...100x higher sample (rubber disc) velocity.

Despite this mistake that could result in a complete disaster, I actually accidentally inputted an interesting test condition: extremely high velocity. As a result, I could observe the wear rate that I was trying in the last 12 months.

Additionally, this condition also closes my samples to tire conditions under high speed braking.

Sorry to my colleagues from the lab for my mistake. SE EU ERREI, FOI TENTANDO ACERTAR. AHAHAHA.

Another day of hyperspectral image photos. My samples were submitted to a HIS camera in order to identify their conditions after very demanding tribology tests.

A jornada acadêmica e profissional no exterior é repleta de desafios técnicos, culturais e pessoais. Neste artigo, compartilho uma experiência marcante vivida durante meu mestrado em Engenharia Automotiva na Itália, que vai muito além dos carros e da tecnologia: trata-se de autoconhecimento, limites pessoais e a importância de saber equilibrar oportunidades com bem-estar.
