Abstract

Bangsa Indonesia dengan jumlah penduduk 275.773.800 jiwa pada pertengahan tahun 2022 berdasarkan data Badan Pusat Statistik (BPS), terdapat sejumlah 428.006.000 kali penggunaan kereta api indonesia yang tercatat melakukan mobilisasi tertinggi pada tahun 2019. Hal ini mengindikasikan besarnya kebutuhan mobilisasi masyarakat Indonesia dengan menggunakan kereta api pada repetisi yang tinggi. Solusi untuk memenuhi kebutuhan akan mobilitas yang tinggi tersebut, perlu dibangun dan digunakan sistem transportasi yang cepat dan nyaman. High-Speed Train (HST) merupakan salah satu solusi yang tepat dengan berbagai keuntungan diantaranya, kapasitas penumpang hingga 1200 pada 16 gerbong dan kecepatan yang tinggi dapat menempuh 350 Km/Jam. Pada kecepatan kereta api di atas 200 km/jam (124 mph) terjadi beberapa hal yang menyebabkan kereta pada kondisi yaitu, dampak cacat geometrik meningkat, daya rekat lintasan berkurang, tidak mudah nya pengemudi untuk mengidentifikasi sinyal sisi lintasan dan terutama adanya fluktuasi displacement atau perpindahan posisi yang signifikan pada kereta akibat kondisi atau kontur rail. Perlu dilakukan analisis pada suspensi kereta api agar meengetahui variabel yang dapat mengakomodasi kenyamanan dan ketahanan. Pada penelitian ini dilakukan analisis suspensi aktif dengan sistem kontrol Proportional Integral Derivative (PID) dan metode simulasi sistem dinamis HST yang ditinjau dari bidang x-z (vertikal), y-z (lateral) dan x-y (longitudinal) pada software Matlab Simulink. Simulasi sistem dinamis suspensi dilakukan menggunakan parameter berupa massa carbody sebesar 55.000 Kg, massa Bogie sebesar 2500 Kg, massa wheelset sebesar 1900 Kg, koefisien pegas, koefisien damper, koefisien kontak rail-wheel dan dimensi bogie yang ditentukan berdasarkan data pada penelitian terdahulu. Input yang digunakan merupakan irregularities track signal berdasarkan Gaussian White Noise (Vertikal dan Lateral) dan step input pada longotudinal (Displacement akibat pengereman) dengan maksimal amplitudo 0,07 m. Model sistem dinamis tergintegrasi dengan model sistem konntrol PID dibuat dan dilakukan simulasi pada software Matlab Simulink. Hasil analisis kinerja dengan sistem kontrol PID pada sistem suspensi dengan tinjauan vertikal, lateral dan longitudinal meghasilkan nilai akselerasi yang lebih kecil dengan penurunan sebesar 13,2% dengan actuator force (F_s) maksimum sebesar 2,055 N ( Vertikal ), 65 % (Lateral) dengan actuator force (F_sl) maksimum sebesar 117 N dan 22,6 % ( Longitudinal) dengan actuator force (F_sh) maksimum sebesar 1700 N. Hasil seluruh kinerja suspensi sesuai standar operasional High-Speed Train Jakarta-Surabaya selama 4 jam dan dikategorikan sebagai Very Comfortable berdasarkan ISO 2631.

The Indonesian nation with a population of 275,773,800 in mid-2022 based on data from the Central Statistics Agency (BPS), there were 428,006,000 times the use of Indonesian trains was recorded as carrying out the highest mobilization in 2019. This indicates the great need for mobilization of the Indonesian people by using the train at high reps. The solution to meet the need for high mobility requires building and using a fast and comfortable transportation system. The High-Speed Train (HST) is one of the right solutions with various advantages including, a passenger capacity of up to 1200 in 16 carriages and a high speed that can travel 350 Km/hour. At train speeds above 200 km/h (124 mph) several things occur which cause the train to be in such a condition, namely, the impact of geometric defects increases, track adhesion decreases, it is not easy for the driver to identify the track side signals and especially the fluctuations in displacement. significant position on the train due to the condition or contour of the rail. It is necessary to analyze the train suspension in order to find out the variables that can accommodate comfort and durability. In this research, active suspension optimization was carried out with the Proportional Integral Derivative (PID) control system and the HST dynamic system simulation method in terms of the x-z (vertical), y-z (lateral) and x-y (longitudinal) planes in Matlab Simulink software. Suspension dynamic system simulation was carried out using parameters such as carbody mass of 55,000 Kg, Bogie mass of 2500 Kg, wheelset mass of 1900 Kg, spring coefficient, damper coefficient, rail-wheel contact coefficient and bogie dimensions determined based on data from previous studies. The input used is irregularities track signal based on Gaussian White Noise (Vertical and Lateral) and step input on longotudinal (Displacement due to braking) with a maximum amplitude of 0.07 m. The integrated dynamic system model with the PID control system model was created and simulated using Matlab Simulink software. The results of optimization performance with the PID control system on the suspension system with vertical, lateral and longitudinal views produce a smaller acceleration value with a decrease of 13.2% with a maximum actuator force (F_s) of 2.055 N (Vertical), 65% (Lateral) with maximum actuator force (F_sl) of 117 N and 22.6% (Longitudinal) with a maximum actuator force (F_sh) of 1700 N. The results of all suspension performance comply with the operational standards of the Jakarta-Surabaya High-Speed Train for 4 hours and are categorized as Very Comfortable based on ISO 2631.
