Abstract

Sistem pengereman kereta merupakan salah satu sistem vital yang berperan dalam memastikan keselamatan pengoperasian kereta. Salah satu tantangan utama dalam desain sistem pengereman kereta adalah memastikan bahwa sistem ini dapat berfungsi dengan andal dalam berbagai kondisi operasional. Penelitian ini bertujuan memahami performa pengereman, karakteristik slip, serta respon suspensi dan coupler pada sistem pengereman kereta KCIC400AF. Model kereta terdiri dari 4
gerbong dimana antara setiap gerbong dihubungkan dengan coupler fleksibel. Pemodelan dan simulasi dilakukan menggunakan aplikasi MATLAB dan SIMULINK dengan variasi penelitian berupa kecepatan awal 120, 240, dan 350 km/h; kondisi rel kering dan basah; serta tekanan aktuator 0,25; 0,5; 0,75; dan 1 MPa. Hasil simulasi menunjukkan bahwa jarak pengereman, kecepatan, serta perlambatan sesuai dengan persamaan gerak translasi dan dipengaruhi oleh kecepatan awal, kondisi rel, dan tekanan aktuator. Untuk karakteristik slip, tekanan aktuator dan kondisi rel berpengaruh terhadap slip serta kecepatan slip pada roda bogie belakang cenderung lebih tinggi dibandingkan roda bogie depan. Respon suspensi ipengaruhi oleh tekanan aktuator dimana seiring bertambahnya tekanan aktuator, maka nilai perpindahan suspensi bertambah namun nilai overshoot berkurang. respon coupler di awal pengereman sama untuk setiap variasi penelitian dimana coupler antara gerbong pertama dan kedua serta antara gerbong kedua dan ketiga merapat, sedangkan coupler antara gerbong ketiga dan keempat meregang. Respon coupler juga dipengaruhi oleh fenomena locking serta kondisi rel yang mempengaruhi interaksi
antar coupler serta delay pada respon gerbong paling belakang.

The train braking system is one of the systems with a vital role in ensuring the safety of the train’s operation. One of the main challenges in the design of train braking systems is to ensure that the system can function reliably under various operational conditions. This study aims to gain a better understanding of the braking performance, slip characteristics, and suspension and coupler characteristics of the KCIC400AF train braking system. The train model consists of 4 carriages with flexible couplers connecting between carriages. Modelling and simulation is done by using MATLAB and SIMULINK software with testing parameters such as initial velocity at 120, 240, and 350 km/h; dry and wet rail conditions; and actuator pressures at 0,25; 0,5; 0,75; and 1 MPa. Simulation results show that braking distance, velocity, and deceleration complies with the translational equation of motion and is influenced by initial velocity, rail conditions, and actuator pressure. For slip characteristics, actuator pressure and rail conditions affects slip and that the rear bogie wheel slip tends to be higher than the front. Suspension response is influenced by actuator pressure, where as pressure increases, suspension displacement increases, but overshoot decreases. For all testing parameters, coupler characteristics at the early stages of braking display the same behavior where the coupler between the first and second carriage and also the coupler between the second and third carriage compresses, while the coupler between the third and fourth carriage expands. Coupler response is also influenced by wheel locking and the rail conditions which affects the interaction between couplers and the delay of the rear carriage.
