Abstract

Fasilitas penunjang untuk penyandang tuna daksa perlu diperhatikan agar dapat setara dengan manusia selaknya. Salah satu penunjang bagi penyandang tuna daksa khusunya,memerlukan kursi roda. Seiring berkembangnya teknologi beberapa inovasi muncul untuk fasilitas yang lebih baik. Kursi roda dengan motor listrik merupakan salah satu inovasi untuk mempermudah pengguan kursi roda. Dengan background study Teknik Mesin yang mempelajari analisa struktur,dilakukan peneletian analisa struktur sambungan kursi roda dengan skuter listrik. Tahapan penelitian ini terdiri dari studi literatur, observasi, penentuan parameter desain, pemodelan struktur 3D menggunakan software Computer Aided Drawing, perhitungan teoritis, analisis kekuatan struktur dan fatigue dengan software berbasis metode elemen hingga, dan validasi hasil simulasi dengan hasil perhitungan teoritis. Didapatkan hasil kekuatan von mises dan Safety Factor dengan modifikasi pada bagian batang silinder pejal dan jarak tumpuan bagian tengah batang yang sesuai dengan parameter yaitu safety factor beban dinamis dan efektifitas penggunaan material. Hasil simulasi diameter batang 14 mm dan jarak tumpuan ttitik B&D 203 mm dengan hasil equivalent von mises dan safety factor 174,07 MPa dan 2,5.Nilai fatigue life desain modifikasi dengan rasio tengan siklik 0,39 adalah 775560 cycle. Nilai tersebut divalidasi dengan aturan palmgreen miner dan didaptkan nilai error sebesar 5,21%

Supporting facilities for people with disabilities need to be considered so that they can be on par with humans. One of the supports for disabled people, especially, requires a wheelchair. As technology develops, several innovations emerge for better facilities. A wheelchair with an electric motor is one of the innovations to make it easier to use a wheelchair. With a background study in Mechanical Engineering studying structural analysis, a structural analysis of the connection between a wheelchair and an electric scooter was carried out. The stages of this research consisted of literature study, observation, determination of design parameters, 3D structural modeling using Computer Aided Drawing software, theoretical calculations, structural strength and fatigue analysis using finite element method based software, and validation of simulation results with theoretical calculation results. The results of von Mises strength and Safety Factor were obtained with modifications to the solid cylindrical rod section and the center rod spacing according to the parameters, namely the dynamic load safety factor and the effectiveness of material use. The simulation results of a stem diameter of 14 mm and 203 mm B&D bearing distance with equivalent von Mises results and a safety factor of 174.07 MPa and 2.5. The fatigue life value of the modified design with a cyclic arm ratio of 0.39 is 775560 cycles. This value is validated by palmgreen miner rules and an error value of 5.21% is obtained
