"ABSTRACT
" Besarnya nilai akselerasi sebuah kendaraan yang dihasilkan, dapat dihitung lewat besar gaya traksi yang keluar dari ban ke lintasan. Ukuran roda dan gardan di dalam sistem penggerak kendaraan dapat mempengaruhi nilai gaya traksi tersebut. Semakin kecil ukuran roda dan roda gigi gardan yang digunakan, maka gaya traksi yang dihasilkan bertambah akan tetapi kecepatan maksimal kendaraan akan berkurang. Sebaliknya, dengan memperbesar ukuran roda dan gardan akan menurunkan gaya traksi namun menambah kecepatan maksimal kendaraan. Oleh sebab itu, lewat penelitian ini dicari ukuran roda dan roda gigi gardan yang optimal. Metode yang digunakan dalam penelitian ini adalah dengan mengumpulkan data sekunder dan data primer. Data sekunder meliputi torsi mesin, rasio gigi kotak transimi, rasio gigi gardan, regulasi kompetisi FSAE, dan lintasan perlombaan. sedangkan, data primer didapatkan lewat simulasi program perangkat lunak OptimumLap. Dari hasil penelitian ini, didapatkan ukuran roda sebesar 20.6 inci dan ukuran roda gigi garda sebesar 43T sehingga dapat memperoleh waktu 3.79 detik pada simulasi akselerasi kendaraan pada lintasan lurus berjarak 75 meter "
" "ABSTRACT
" The Amount of acceleration produce can be measured by traction force acting between the wheels and road. The size of wheels and differential gear are supposedly affecting these traction force. As smaller size of wheels and differential gear used will increase the traction force but decreasing vehicle top speed. vice versa, bigger wheel and differential gear size will reduce traction force but increase vehicle top speed. Therefore, this study should find the optimal wheel and differential gear size. The method used in this study is by collecting secondary and primary data. Secondary data which consist of engine torque, ratio of gear in gearbox, final drive ratio, FSAE regulation, and circuit used in competition. While primary data acquired using software simulation program OptimumLap. From this study, obtained the size of wheels 20.6 inch anddifferential gear 43T to achieve 3.79 seconds from vehicle acceleration simulation in 75 meters straight circuit.

Semakin ketatnya persaingan antar perusahaan otomotif di Indonesia membuat sistem transportasi pengadaan bahan baku pada perusahaan manufaktur dari pemasok ke pabrik produksi dituntut untuk menjadi sangat efektif dan efisien. Salah satu penyebabnya adalah karena alokasi biaya transportasi sebesar ⅓-⅔ dari biaya logistik. Penelitian ini bertujuan untuk member gambaran model sistem milkrun jika diterapkan pada PT ISI, Keuntungannya dari sistem ini ialah meminimalkan jarak tempuh truk yang mengambil komponen dari pemasok sehingga nantinya diperoleh rute dan penggunaan jumlah truk yang optimal pada perusahaan untuk menangani masalah pengangkutan komponen. Penyelesaian rute dihasilkan dengan menggunakan metode algoritma Tabu Search dan bantuan program MATLAB. Keunggulan Tabu Search adalah keunikan struktur memori fleksibelnya dan factor ketetanggaan, dapat diaplikasikan dalam berbagai masalah, cepat dalam mencapai tujuan, dan dapat menemukan solusi yang mendekati optimal. Dengan menggunakan metode ini sistem transportasi dapat dioptimalkan sehingga biaya logistik dapat diminimalkan. Hasil yang diperoleh dari penelitian ini adalah penurunan jarak tempuh 394 km atau sebesar 30%. ......Increasingly intense competition among automotive companies in Indonesia making the transportation system of components procurement at the manufacturing company from a supplier to the production plant is required to be highly effective and efficient. One reason is because the allocation of transportation costs ⅓-⅔ from logistic cost This study aims to member overview milkrun system model when applied to the PT ISI, The advantage of this system is to minimize the mileage of the truck that takes the components from suppliers so that later acquired routes and use the optimal number of trucks on the company to deal with the transport component. Completion routes generated using Tabu Search algorithm method and MATLAB program assistance. Excellence of Tabu Search is a unique memory structure flexibility and neighborhood factors, can be applied in a variety of problems, faster in achieving objectives, and can find a near optimal solution. By using this method of transportation systems can be optimized so that the logistics costs can be minimized. Results obtained from this study is the decrease in mileage 394 km or by 30% and decrease of transportation cost by 43%.

The book provides the essential features necessary to understand and apply the mathematical-mechanical characteristics and tools for vehicle dynamics including control mechanism. An introduction to passenger car modeling of different complexities provides the basics for the dynamical behavior and presents vehicle models later used for the application of control strategies. The presented modeling of the tire behavior, also for transient changes of the contact patch properties, shows the necessary mathematical descriptions used for the simulation of the vehicle dynamics. The introduction to control for cars and its extension to complex applications using e.g. observers and state estimators is a main part of the book. Finally the formulation of proper multibody codes for the simulation leads to the integration of all parts. Examples of simulations and corresponding test verifications show the profit of such a theoretical support for the investigation of the dynamics of passenger cars.

Two-stroke engines are far simpler than four-stroke engines from a physical perspective. For a given brake output, two-stroke engines are lighter, easier to work on, and provide higher power-to-weight ratio than four-stroke engines, making them suitable for small platform applications. However, conventional two-stroke engines have a reputation for generating smoke and unburned fuel, meaning they may not meet many emissions regulations, now enforced around the world. Thus, for many decades two-stroke engines have not been not favored, giving way to four-stroke engines for dominant applications, especially for mobile power-generation purposes. In the quest to improve the potential of such an engine, a group of researchers from the Automotive Development Centre (ADC), Universiti Teknologi Malaysia (UTM), has developed a 125 cc, air-cooled stepped-piston engine to demonstrate the higher power-to-weight ratio feature, apart from overcoming emission reduction. The engine is designed to mitigate the problem of mixture short circuiting, which is the major hindrance to combustion efficiency. To this end, they have incorporated a three-port stratification strategy into the engine. This paper provides an overview related to the earlier work done to integrate the necessary features and highlights some of the performance features of this unique engine design

This volume gives an overview on recent developments for various applications of modern engineering design. Different engineering disciplines such as mechanical, materials, computer and process engineering provide the foundation for the design and development of improved structures, materials and processes. The modern design cycle is characterized by an interaction of different disciplines and a strong shift to computer-based approaches where only a few experiments are performed for verification purposes. A major driver for this development is the increased demand for cost reduction, which is also connected to environmental demands. In the transportation industry (e.g. automotive or aerospace), this is connected with the demand for higher fuel efficiency, which is related to the operational costs and the lower harm for the environment. One way to fulfil such requirements are lighter structures and/or improved processes for energy conversion. Another emerging area is the interaction of classical engineering with the health and medical sector. In this book, many examples of the mentioned design applications are presented.
