1. Topological and Topographical Optimization of Automotive Spring Lower Seat
Abstract The design of a suspension system emphasizes weight reduction in this high-computation technology era. Understanding that the reduction of suspension mass can lead to cost and material reduction is important; moreover, the riding performance of the vehicle should be improved. Topology and topography structure optimization for the spring lower seat i

2. Estudo dos mecanismos de fadiga e análise de desempenho em mola para válvula automotiva em regime de alto e ultra-alto ciclo. / Study on the fatigue mechanisms and performance analysis in automotive valve spring under high-and-ultra-high-cycle regime.
This paper presents a study on the valve spring fatigue mechanisms, carried out through analysis of mechanical behavior correlated to microstructural aspect. The samples were made of high strength steel Si-Cr, obtained by conventional (quenching and tempering) and unconventional (austempering) heat treatments, generating a single level of hardness (approxima

3. Numerical and experimental analysis of the residual stresses induced by shot peening in automotive springs. / Análise numérico-experimental das tensões residuais induzidas por jateamento com granalha em molas automotivas.
The shot peening is a cold-working mechanical process where a stream of tiny small balls is impelled against the surface of components. Each impact causes plastic deformation and introduces compressive residual stresses on the surface, which consequently increases their resistance to fatigue. This process is widely used in the automotive industry, particular

4. Disc brake noise analysis using instability of complex eigenvalue / Instabilidade de freios a disco por analise de autovalor complexo
To understand, model and mitigate disc brake noise is still one of the greatest challenges for the automotive industry. It is substantially important for manufacturers and suppliers to predict the disc brake noise in a design phase. Squeal is a brake noise in the 1-15 kHz frequency range, and can be defined as a self-excited friction problem, which can gener
