Pada era modern ini, banyak perangkat lunak yang mendukung pembelajaran khususnya dibidang teknik dalam melakukan simulasi sebelum diimplementasikan pada keadaan sebenarnya dengan tujuan untuk mengetahui parameter-parameter yang dibutuhkan agar suatu alat agar bisa bekerja dengan baik, stabil tanpa harus melakukan percobaan di medan sebenarnya dengan resiko yang tinggi. CarSim , sebuah perangkat lunak yang berfokus pada uji dan analisa dinamika kendaraan, dalam skripsi ini akan dicoba untuk membuat profil jalan dengan tujuan untuk dapat dijadikan simulator uji dinamikan kendaraan di lingkungan kampus Universitas Indonesia. Jalan yang akan dibangun dibuat mirip dengan aslinya mulai dari jalur, ketinggian, serta bangunan disekitarnya agar terlihat realistis. Minimnya sumber acuan untuk memahami perangkat lunak CarSim di internet tidak membuat hal ini menjadi tidak mungkin. Dengan pemahaman dasar, percobaan panjang secara mandiri serta membaca berbagai sumber literatur, perancangan simulator jalan Universitas Indonesia berhasil dibangun. Simulator ini juga masih memiliki kemungkinan besar untuk dapat dikembangkan lebih lanjut kedepannya.

ABSTRACT
In this modern era, many softwares are provided to support learning process especially in the field of engineering in doing a simulation before a tool can be implemented in the actual situation with the aim to know the parameters needed without having to conduct experiments in the real field with high risks. CarSim , a software that focuses on vehicle dynamics tests and analysis, in this paper will be tried to create a road profile with the aim to become a simulator to analyze a vehicle dynamics behavior in University of Indonesia. The path that is about to built is made as close as possible to its real form, whether from its path, elevation, and buildings to make it look realistic. The lack of a reference source in understanding CarSim on the internet does not make this experiments impossible. With a basic understanding, a long independent research and reading literatures, University of Indonesia simulator has successfully been built. This simulator also still has a great possibility to be developed in the future.

ABSTRACT
Safety in driving highly developed by the automotive industry. One of the components that play an important role in providing safety for the driver while driving is the Vehicle Dynamics Control. This system is commonly known as Vehicle Dynamics Control or Electronic Stability Control all types of systems applied in control systems for safety and a different name as the automotive industry. The VDC system is functioning when the driver speeding on the street turn and perform over steering and under steering, the car remains in the stability not until crashing to the upside. This research is making the car control by detecting and minimizing slip given by the torque on each tire with multistage predictive controller . So that when the driver lost control then automatically controls the system will do the braking automaticly. The braking based on the calculation yaw rate then gave direct orders to each wheel. The front wheels will prevent oversteer and the rear wheels will prevent understeer.

Sayap belakang (SB) merupakan salah satu pesawat aerodinamika yang paling terkemuka, sehingga melahirkan banyak studi serta analisis terhadapnya. Namun, banyak dari studi tersebut tidak menyinggung efek terhadap dinamika kendaraan dari SB tersebut. Studi ini bertujuan untuk mengukur peningkatan performa pada sebuah mobil balap karena penggunaan SB melalui simulasi CFD dan analisa empirik. Studi ini dilakukan pada model CAD Williams F1 FW42, di mana pada pengujian CFD dibuat 7 juta meshing cells. Simulasi ini menggunakan model turbulensi K-Ɛ untuk mendapatkan data gaya angkat dan hambat. Performa mobil, seperti kurva traksi dan rasio gigi, diperoleh dengan menggunakan data telemetri pada Sirkuit Autódromo José Carlos Pace (Interlagos), yang juga digunakan untuk memodelkan performa mobil hasil simulasi di dunia nyata. Dari hasil studi, didapatkan bahwa penggunaan SB berkontribusi terhadap 27.3% total gaya angkat, 28.5% total gaya hambat, dan meningkatkan 20.9% kelajuan maksimum pada sebuah tikungan. Hasil-hasil tersebut berakumulasi sehingga, secara teoretis, penggunaan SB dapat memangkas waktu putaran hingga 1.745 detik walaupun meningkatkan penggunaan bahan bakar hingga 2.13%. ......The rear wing (RW) is one of the most iconic aerodynamic devices to be put on a car, spawning many analyses and examinations. However, most of those studies on the aerodynamics of a RW do not relate its effects to the vehicular dynamics. This study aims to gauge the performance gains of a race car due to the utilization of the RW, via CFD simulation and empirical analysis. This study is done on a Williams FW42 Formula 1 car, on which CFD testing was conducted using a full-scale CAD model of the car, meshed to 7 million cells. The simulation used K-Ɛ turbulence model to find lift and drag figures. The car’s performance, such as gear ratios and traction band, was approximated using telemetry footage data from a qualifying lap at Autódromo José Carlos Pace (Interlagos) circuit, on which the model car is simulated to run as well. From the study, it was found that on average, the RW contributes to 27.3% of the total downforce generated, 28.5% of the drag, and 4.33% increase in limiting cornering velocity. These results culminate in a theoretical 1.745 second faster lap time for the car equipped with the RW, though with a worse fuel efficiency as seen by a 2.13% increase in fuel consumption.

This book examines the driving dynamics of harvesting machines with large harvesting heads. It looks at how to efficiently use these machines. The author explores a common problem that hinders machine performance when harvesting with very large headers. He deals with concepts for reducing the undesired effects of vehicle dynamics when using these machines. With the steadily increasing capacity of harvesting machines, the working widths of the harvesting heads get wider and the headers get heavier. It has become essential with these giant headers to use header height sensors and header control systems to avoid the headers from being run into the ground when encountering elevation changes in the terrain. A fundamental limitation of the viable speed of header height adjustments arises from the combination of the wider and heavier headers with soft agricultural tires. The current solution to find an appropriate speed of header height adjustments is to perform a header calibration whenever a new header is attached to the machine and to endow the machine operator with the capability to tweak the speed of adjustments manually. The result of an inappropriate speed of height adjustments is a reduction in overall productivity and an under-utilization of the harvesting machine. The author looks at ways to prevent this. He offers detailed modeling of the vertical dynamics including dynamic wheel loads. In addition, the book contains results from simulations and machine tests.
