Abstract Research into converting waste into viable eco-friendly products has gained global concern. Using natural fibres and pulverized metallic waste becomes necessary to reduce noxious environmental emissions due to indiscriminately occupying the land. This study reviews the literature in the broad area of green composites in search of materials that can be used in automotive brake pads. Materials made by biocomposite, rather than fossil fuels, will be favoured. A database containing the tribo-mechanical performance of numerous potential components for the future green composite was established using the technical details of bio-polymers and natural reinforcements. The development… More > Graphic Abstract

Abstract To better solve the issue with abnormal failure of electric motor unit (EMU) brake pad resulted from various random factors in the ever-changing operating environment, in this paper, a new evaluation method of performance prediction and abnormity decision is proposed based on the Multivariate integrated random walk (MIRW) model. In this method, the state space model of the EMU brake pad performance degradation is firstly established. And then based on the observed data, the brake pad performance degradation trend is extracted by the fixed interval forward - backward smoothing algorithm. Based on it, the future… More >

Abstract The purpose of the present work is to study the disc brake squeal problem for passenger cars in order to reduce the instable high frequency squeal modes. The ABAQUS/Standard implicit method was used to perform dynamic contact vibration analysis of the current disc brake finite element model. The disc brake system studied here contains the caliper, bracket, brake disc, and brake pad. Notice that brake pad in general contains both brake lining and brake shoe. The brake pad with a specific chamfer pattern and the brake disc with a series of cooling ribs for ventilation… More >
