Abstract

ama ini dimanfaatkan untuk meredam perubahan kecepatan pada mobil dengan cara memanfaatkan momen inersia. Karena momen inersia yang dimilikinya, flywheel mampu menyimpan energi mekanik dalam waktu singkat, membuat mesin berputar dengan lebih lembut. Baru-baru ini dilakukan penelitian lebih lanjut mengenai pemanfaatan dari flywheel, yakni pada sistem suspensi. Sistem suspensi konvensional biasanya hanya terdiri dari pegas dan peredam, sedangkan massa jarang sekali digunakan. Padahal massa juga mampu memberikan efek seperti redaman apabila dipasangkan di sana dalam bentuk flywheel. Akan tetapi selama ini penelitian yang dilakukan terbatas pada flywheel dengan momen inersia yang konstan (Constant Moment of Inertia). Dalam tugas akhir ini, shock absorber yang akan dimodelkan memanfaatkan prinsip hidraulis dari fluida untuk mentransfer energi pada suspensi menuju ke flywheel. Adapun sistem dari pemodelan seperempat kendaraan (quarter car) memiliki dua derajat kebebasan. ======================================================================================================== Flywheel is a device that is commonly used to restore rotational energy due to its inertia. Usually flywheel is applied on vehicle’s engine or conventional sewing machine. Currently, some people did research about the application of flywheel, which is on shock absorber. A conventional suspension usually consists of spring and damper. A mass is rarely used though it could provide an effect like damper when being applied as flywheel. Those people researched it but the flywheels they used as object were Constant Moment of Inertia (CMI) Flywheel. In this thesis, something different will be done where Variable Moment of Inertia (VMI) Flywheel is being used as an object. The first step to do is build mathematical model of hydraulic suspension. Then, do the simulation of hydraulic suspension before and after applied into quarter car model to get dynamic behavior. Some inputs will be varied, such as frequency of sinusoidal input and the material of slider
