Abstract

ABSTRAK Penelitian ini bertujuan untuk menganalisis kinerja struktur kursi roda multi guna menggunakan metode elemen hingga (FEA) dan perhitungan analitik. Model kursi roda dibangun dan dianalisis menggunakan perangkat lunak FEA untuk mendapatkan distribusi tegangan, perpindahan, dan tegangan lentur. Hasil FEA menunjukkan nilai tegangan maksimum sebesar 415 MPa, perpindahan maksimum 46 mm, dan tegangan lentur maksimum 407 MPa, melebihi batas sifat mekanik material aluminium 6061. Hasil analitik menghasilkan nilai tegangan sebesar 57 MPa pada struktur bagian depan, sedangkan FEA menghasilkan nilai 46 MPa. Perbedaan hasil antara kedua metode ini dapat disebabkan oleh beberapa faktor, seperti asumsi yang digunakan dalam perhitungan analitik dan kompleksitas geometri model FEA. Kesimpulan yang bisa kita ambil dari penelitian tersebut bahwa desain/struktur kursi roda multi guna telah melampaui terhadap nilai-nilai sifat mekanik dari material Aluminium 6061, yang bisa menyebabkan kegagalan struktural pada komponen-komponen nya. Kata Kunci: kursi roda multiguna, finite elemen analisis, analisis struktur ABSTRACT This research aims to analyze the performance of multi-purpose wheelchair structures using the finite element method (FEA) and analytical calculations. A wheelchair model was built and analyzed using FEA software to obtain stress, displacement and bending stress distributions. The FEA results show a maximum stress value of 415 MPa, a maximum displacement of 46 mm, and a maximum bending stress of 407 MPa, exceeding the mechanical properties limit of 6061 aluminum material. The analytical results produce a stress value of 57 MPa in the front structure, while the FEA produces a value of 46 MPa. The difference in results between these two methods can be caused by several factors, such as the assumptions used in analytical calculations and the geometric complexity of the FEA model. The conclusion we can draw from this research is that the design/structure of the multi-purpose wheelchair has exceeded the mechanical property values of the Aluminum 6061 material, which can cause structural failure in the components when fabricated. Keywords: multipurpose wheelchair, finite element analysis, structural analysis
