ANALYSIS BRAKING ENERGY OF BUS TRANSJAKARTA USING FLYWHEEL REGENERATIVE BRAKING TO DETERMINE THE CAPACITY OF FLYWHEEL ENERGY

Author :
SAPUTRA, OKTANTO DARMA ( 2111106001 )




ABSTRAK

Bus Transjakarata merupakan angkutan massal yang beroperasi pada sistem transportasi Bus Rapid Transit BRT di Kota Jakarta yang beroperasi pada rute dengan halte yang disediakan. Banyaknya halte mengakibatkan bus sering melakukan pengereman. Dengan seringnya bus melakukan pengereman dan didukung dengan massa bus yang besar maka ada potensi energi akibat perlambatan yang bisa disimpan regenerative untuk digunakan lagi saat akselerasi. Jika hanya mengandalkan tenaga dari engine untuk akselerasi maka engine akan bekerja dengan beban yang tinggi. Untuk mengurangi beban kerja engine saat akselerasi dapat dibantu menggunakan regenerative braking melalui putaran flywheel. Untuk dapat menganalisa regenerative braking pada Bus Transjakarta maka digunakan beberapa parameter seperti data teknis spesifikasi kendaraan driving cycle regulasi pe-ngereman ECE Economic Commission for Europe gaya hambat kendaraan iii dan FBD pengereman kendaraan. Parameter ini digunakan untuk mengetahui peta distribusi pengereman kendaraan Bus Transjakarta porsi pengereman baik untuk regenerative braking maupun mechanical braking serta mengetahui sebaran energi pengereman pada driving cycle terhadap peta distribusi pengereman kendaraan tersebut. Dari hasil analisa energi pengereman Bus Transjakarta didapatkan porsi regenerative braking roda depan sebesar 0.05g roda belakang sebesar 0.065g dan mechanical braking sebesar 004387g. Energi maksimum yang dihasilkan oleh regenerative braking depan sebesar 963623J dan regenerative braking roda belakang sebesar 12527105J. Dengan pertimbangan ketersediaan ruang pada chasis Bus maka flywheel yang digunakan memiliki spesifikasi diroda depan Dofw0.4m hfw0072m mfw6858kg dengan putaran maksimum 1110539rpm. Sedangkan spesifikasi diroda belakang Dofw0.34m hfw0131m mfw8785kg dengan putaran maksimum 13065165rpm. Untuk energi yang dapat dipenuhi oleh regenerative braking sebesar 4137 dari kebutuhan energi total saat akselerasi.


ABSTRACT

Transjakarta a mass transit system that operates at the transport Bus Rapid Transit BRT in Jakarta which operate on routes with stops provided. The number of bus stops resulting in frequent braking. With frequent bus braking and supported by a large mass of the bus then there is the potential energy that can be saved as a result of deceleration regenerative to be used again during acceleration. If only rely on power from the engine to the acceleration the engine will work with high load. To reduce the workload of the engine during acceleration can be assisted through the use of regenerative braking flywheel rotation. To analyze regenerative braking on TransJakarta bus then used several parameters such as technical data specification vehicles driving cycle braking regulation ECE Economic Commission for Europe drag the vehicle and the vehicle braking FBD. This parameter is used to determine a map of the distribuv tion of the vehicles braking Bus Busway good braking portion for regenerative braking and mechanical braking and know the distribution of braking energy in the driving cycle to braking region of vehicle. From the analysis of TransJakarta bus braking energy obtained regenerative braking portion of 0.05g front wheel rear wheel of 0.065g and mechanical braking of 004387g. Maximum energy generated by front regenerative braking are 963623J and rear regenerative braking are 12527105J. In consideration of the availability of space on bus chassis the flywheel is used has a front wheel specificationsDofw0.4mHfw0072m Mfw6858kg with maximum rotation 1110539rpm. While the rear wheel specifications Dofw0.34m Hfw0131m Mfw8785kg with maximum rotation 13065165rpm. For energy can be met by regenerative braking for 41.37 of the total energy during acceleration.
