Abstract

Sistem suspensi berperan penting dalam mengurangi getaran yang dirasakan oleh pengemudi dan penumpang kendaraan, terutama saat melintasi permukaan jalan yang tidak rata. Salah satu inovasi dalam teknologi suspensi adalah sistem suspensi udara aktif, yang dikembangkan untuk meningkatkan kenyamanan berkendara. Penelitian ini fokus pada rancang bangun sistem suspensi udara aktif untuk kendaraan PHEV yang dikembangkan oleh ITS baik di perancangan elektrikalnya dan mekanikalnya, dalam konteks uji statis. Penelitian dimulai dengan studi literatur mengenai perkembangan sistem suspensi udara aktif, diikuti oleh observasi lapangan terhadap parameter kendaraan PHEV. Selanjutnya, sistem kendali suspensi dirancang dan diproduksi, diikuti oleh perakitan kerangka alat uji dan pengujian sistem kontrol pada suspensi tersebut. Pengujian dilakukan dalam kondisi uji statis dan melihat pengaruh dan respon dari sistem ketika dikenai pembebanan yang sesuai dengan parameter PHEV ITS. Setelah dilakukan rancang bangun sistem dapat disimpulkan bahwa perancangan sistem kendali active air suspension melibatkan pembuatan skematik diagram, pencetakan PCB, dan integrasi kontroler dengan komponen sistem kendali, serta desain dan fabrikasi kerangka alat uji menggunakan besi pejal hitam dan hollow. Sistem ini digunakan pada kendaraan PHEV ITS dengan komponen seperti Arduino Nano sebagai mikrokontroler, solenoid valve, sensor accelerometer MPU6050 dengan jangkauan pengukuran hingga ±8g, pressure sensor Wisner-PT dengan kapasitas maksimum 12 bar, dan sensor ultrasonik HC-SR04 dengan jangkauan 2-400 cm. Hasil uji menunjukkan bahwa semakin besar perbedaan jarak antara kondisi awal dan akhir air spring, semakin besar pula tekanan yang dihasilkan. Selain itu, nilai yang diukur oleh sensor accelerometer telah sesuai dengan standar ISO 2631 dan masuk dalam kategori "Nyaman" dengan rentang 0,315 – 0,63 m/s². ==============================================================================================================================
The suspension system plays a crucial role in reducing vibrations felt by drivers and passengers, especially when traversing uneven road surfaces. One innovation in suspension technology is the active air suspension system, which is developed to enhance driving comfort. This research focuses on the design and development of an active air suspension system for a PHEV vehicle developed by ITS, addressing both electrical and mechanical aspects in a static test context. The study begins with a literature review on the development of active air suspension systems, followed by field observations of the PHEV vehicle's parameters. Subsequently, the suspension control system was designed and produced, followed by the assembly of the test frame and testing of the control system on the suspension. Testing was conducted under static test conditions, observing the impact and response of the system when subjected to loading consistent with the parameters of the ITS PHEV. The conclusion of the design and development process is that the design of the active air suspension control system involves creating schematic diagrams, printing PCBs, and integrating the controller with the control system components, as well as designing and fabricating the test frame using black solid iron and hollow materials. This system is utilized in the ITS PHEV vehicle with components such as an Arduino Nano as the microcontroller, a solenoid valve, an MPU6050 accelerometer sensor with a measurement range of up to ±8g, a Wisner-PT pressure sensor with a maximum measurement capacity of 12 bar, and an HC-SR04 ultrasonic sensor with a measurement range of 2-400 cm. The test results indicate that the greater the difference in distance between the initial and final conditions of the air spring, the greater the pressure produced. Furthermore, the values measured by the accelerometer sensor conform to the ISO 2631 standard and fall within the "Comfortable" category with a range of 0.315 – 0.63 m/s².
