Abstract

Sistem suspensi kendaraan merupakan komponen penting pada kendaraan untuk mengurangi getaran dan meningkatkan kenyamanan. Belakangan telah banyak metode baik secara simulasi maupun eksperimen yang meneliti mengenai suspensi dan faktor yang mempengaruhinya. Sebelumnya telah dilakukan penelitian oleh Windarta pada tahun 2024. Hasil penelitian windarta menunjukkan bahwa supsensi aktif memiliki respon terhadap getaran yang lebih baik dibandingkan dengan suspensi aktif. Hasil pengujian secara statis menunjukkan bahwa pengujian dengan kendaraan setengah bahwa nilai nilai RMS percepatan digolongkan nyaman dengan nilai 0,361 m/s2.Berdasarkan paparan diatas, penulis melakukan penelitian dengan menambahkan poros engkol agar mengetahui respon secara real time. Serta mengetahui performa suspensi, mengetahui grafik dari pengujian dan dapat dibandingkan dengan hasil dari simulasi. Pada penelitian ini sistem diuji dengan menggunakan variasi tekanan udara pada air spring dan perubahan ketinggian suspensi, percepatan udara serta dianalisis pengaruhnya terhadap percepatan vertikal kendaraan. Alat dan bahan penelitian ini mencakup model setengah kendaraan yang dihubungkan poros engkol, sensor tekanan sensor percepatan dan sensor ketinggian yang terhubung dengan Arduino Uno. Adapun pengujian ini dilakukan dengan menghidupkan kompresor untuk mengisi udara. Motor dihidupkan dan poros engkol bergerak. Kemudian, data dicatat dengan bantuuan arduino Uno yang terhubung dengan sensor tekanan , sensor percepatan dan sensor ketinggian. Berdasarkan hasil eksperimen didapatkan bahwa bahwa sistem mampu merespons variasi tekanan udara dengan perubahan tinggi suspensi dan percepatan yang terukur secara presisi. Nilai RMS percepatan vertikal rata-rata yang diperoleh adalah 1,01 m/s², yang dikategorikan dalam tingkat kenyamanan “cukup nyaman” berdasarkan standar ISO 2631.Selain itu, semakin tinggi tekanan udara yang diberikan, semakin rendah percepatan vertikal yang dihasilkan. Ketiga, terdapat konsistensi konseptual yang memiliki kesamaan dengan hasil simulasi dimana percepatan akan turun dengan naiknya ketinggian akibat adanya getaran.

The vehicle suspension system is an important component of a vehicle for reducing vibrations and improving comfort. Recently, many methods, both thru simulation and experimentation, have been used to study suspensions and the factors that influence them. Previously, research was conducted by Windarta in 2024. The results of Windarta's research show that active suspension has a better response to vibrations compared to passive suspension. The statistical test results show that testing with half the vehicle resulted in RMS acceleration values classified as comfortable, with a value of 0.361 m/s2. Based on the presentation above, the author conducted research by adding a crankshaft to determine the real-time response. This was done to understand the suspension performance, analyze the test graphs, and compare them with the simulation results. In this study, the system was tested using variations in air spring air pressure and changes in suspension height, air acceleration, and the effects of these on the vehicle's vertical acceleration were analyzed. The tools and materials for this research include a half-vehicle model connected to a crankshaft, pressure sensors, acceleration sensors, and height sensors connected to an Arduino Uno. The testing was conducted by turning on the compressor to fill the air. The motor was started and the crankshaft moved. Then, the data was recorded with the help of an Arduino Uno connected to a pressure sensor, an acceleration sensor, and an altitude sensor. Based on the experimental results, it was found that the system is able to respond to variations in air pressure with changes in suspension height and acceleration that are precisely measured. The average vertical acceleration RMS value obtained was 1.01 m/s², which is categorized as "fairly comfortable" according to ISO 2631 standards. Additionally, the higher the air pressure applied, the lower the resulting vertical acceleration. Third, there is conceptual consistency that is similar to the simulation results, where acceleration will decrease with increasing altitude due to vibration.
