The use of a virtual analysis approach to develop and modify vehicle sub-system is becoming popular nowadays as it is less time consuming, reduces the workmanship and overall testing cost compared to the experimental approach. In this paper, an actual virtual suspension system based on UiTM’s Perodua Eco Challenge (PEC) competition fullbody vehicle...

Brake friction materials are composed of four components, namely the reinforcing fibres, binders, fillers and frictional additives. The phenolic resin is used as the binder to hold the composition together and maintain the structural integrity of the brake material during braking process. Three semi-metallic material formulations were prepared by p...

Brake system is used to slow down and finally stop a motor vehicle and friction material is one of the components of the brake system. In this study, eight formulations of brake friction materials were developed through powder metallurgy processes. The samples were subjected to physical, mechanical, friction and on-road performance tests to investi...

A formula-type car design with fendered rear tyres is chosen as the ARTeC's design for 2011 Perodua Eco-Challenge. This paper aims at investigating aerodynamics of ARTeC's EMo-C car, measuring drag coefficient in particular and observing airflow around the body. There are two means of measuring the drag, the first is by simulating the air flow via...

Thin-walled metallic tubular structures are generally used as impact energy absorber in automotive structures due to their ease of fabrication and installation, high energy absorption capacity and long stroke. However, unlike a normal passenger car where the impact energy can be distributed throughout the whole structure, the impact energy absorbin...

Friction materials are complex mix of fibres, modifiers, additives, fillers and a binder resin which holds them together and are composed of between 5 and 20 elements in the composition. Each element has its own function and changing any element or its weight percentage will change the friction material properties. Besides, there is no rule of th...

Enam pad brek yang telah dibangunkan melalui teknik serbuk metalurgi telah menjalani ujian prestasi di atas jalan mengikut “Annex 3 Economic European Community Regulation 13 (ECE R13)”. Setiap sampel telah menjalani ujian sejuk, pudar dan pemulihan. Keputusan ujian menunjukkan hanya sampel S2, S14, S27 dan S31 menepati keperluan minimum purata nyah...

Abstrak. Analisis data kecelakaan jalan raya dijalankan adalah untuk tempoh empat belas tahun bermula dari tahun 1985 hingga tahun 1998 yang diperolehi daripada Laporan Perangkaan Kecelakaan Jalan Raya. Bilangan kemalangan bagi setiap 1,000,000 km motosikal berdaftar meningkat daripada 0.45 pada tahun 1990 kepada 0.82 pada tahun 1998 dengan peningk...

Four formulations of composite friction material for passenger car were developed using powder metallurgy technique. The processes of developing the composite friction materials are as follows; (i) selection of raw materials, (ii) mixing, (iii) preparation of backing plate, (iv) compacting, (v) surface grinding, (vi) post-baking, and (vii) testing....

Disc pads for passenger vehicles were subjected to physical tests such as hardness, specific gravity and surface roughness as well as friction test according to Malaysia Standard MS 1164: 1988. In the friction test, each sample was subjected to an applied load of 600 N, braking time of 400 seconds (total braking time), and rotational speed of 750 r...

Bahan geseran pad brek yang dikeluarkan oleh pembuat asal alat (OEM) dan dipasang pada sesebuah kenderaan telah dihasilkan dan dibangunkan dengan kerjasama pembuat kenderaan. Alat asal (OE) pad brek yang dihasilkan untuk telah menjalani ujian dan menepati penentuan prestasi. Pad brek yang dihasilkan oleh pembuat alat ganti (REM) pada lazimnya diban...

In this work, seven samples of newly developed friction material formulations were subjected to Rockwell hardness tests in accordance with Malaysia standard MS 474, Part 2. 2003. The samples were developed through powder metallurgy technique consisting of the following processing stages; powder selection, weighing, compaction, post baking and finis...
