1. Effects of material properties on generation of brake squeal noise using finite element method
AbstractThis research paper is concerned with the disc brake squeal problem for passenger cars. The aim of the present research is developing a finite element model of the disc brake assembly in order to improve understanding of the influence of Young's modulus on squeal generation. A detailed finite element model of the whole disc brake assembly that integr

2. Estudo da relação entre propriedades de compósitos de fricção aplicados a sistemas de freio a disco e a propensão à ocorrência de Squeal Noise
Automotive brake systems are very often susceptible to generate high frequency noise as a result of a self excited vibration. This phenomenon is generically nominated brake squeal noise and is the subject of many studies which intend to identify and describe its exciting mechanism and to propose counter measures to avoid its occurrence. One key subject yet t

3. 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

4. Análise de materiais de fundo de alto amortecimento e de seus efeitos em pastilhas de freio
Ruídos de freio apresentam-se hoje como um dos principais problemas relacionados ao conforto do motorista em automóveis modernos. O elevado fator de atrito entre disco e pastilhas, necessário para proporcionar um adequado desempenho de frenagem aos atuais veículos de passeio, tem aumentado significativamente a propensão à ocorrência de ruídos do tipo

5. Reduction of squeal noise from disc brake systems using constrained layer damping
Squeal noise generation during braking is a complicated dynamic problem which automobile manufacturers have confronted for decades. Customer complaints result in significant yearly warranty costs. More importantly, customer dissatisfaction may result in rejection of certain brands of brake systems. In order to produce quality automobiles that can compete in
