Abstract

Ambulan memiliki peran penting dalam transportasi pasien dan sering mengalami akselerasi, deselerasi, serta manuver cepat. Dinamika ini dapat menyebabkan getaran dan ketidakstabilan yang berdampak pada kenyamanan dan keamanan pasien. Penelitian ini bertujuan meningkatkan kenyamanan pasien dengan menerapkan sistem Dynamic Vibration Absorber (DVA) pada brankar ambulan. DVA mencakup massa tambahan yang dihubungkan melalui sistem peredam untuk mengurangi efek pitching dan bouncing, sesuai standar ISO 2631. Optimasi parameter seperti jarak pusat gravitasi brankar ke DVA, konstanta pegas, konstanta redaman, dan massa dilakukan menggunakan algoritma genetika (Genetic Algorithm, GA). Dengan menggunakan model setengah kendaraan dan profil jalan sinusoidal, penelitian ini mensimulasikan dan menganalisis dampak DVA dalam mengurangi getaran. Hasil penelitian menunjukkan peningkatan signifikan dalam kenyamanan dan keamanan pasien selama perjalanan ambulan. DVA pada brankar ambulans menciptakan kondisi yang lebih stabil dan nyaman, sehingga DVA dapat diaplikasikan pada brankar ambulans yang sudah ada.

Ambulances play a crucial role in patient transportation and are often subjected to rapid accelerations, decelerations, and maneuvering. These dynamics can cause vibrations and instability, significantly impacting patient comfort and safety. This research aims to enhance patient comfort by implementing a Dynamic Vibration Absorber (DVA) system on the stretcher of an ambulance. The DVA incorporates additional mass connected through a damping system to reduce pitching and bouncing effects, improving comfort levels according to ISO 2631 standards. The optimization of parameters such as the distance between the stretcher's center of gravity and the DVA, spring constants, damping coefficients, and mass is carried out using Genetic Algorithm (GA). By using a half-car model and sinusoidal road profiles, this study simulates and analyzes the impact of DVA on reducing vibrations. The results demonstrate a significant improvement in patient comfort and safety during ambulance transport. Application of this DVA offers solution for a safer patient transport, that can be applied to existing stretcher.
