Winarto, Tri Tiadi (2018) Analisis Distribusi Tegangan Monocoque Chassis Carbon Fiber Honeycomb Core Pada Mobil Hemat Energi Urban Concept. Sarjana thesis, Universitas Brawijaya.
Abstract
Merancang kendaraan hemat energi merupakan salah satu upaya untuk menurunkan konsumsi energi di sektor transportasi. Faktor-faktor yang yang diperhatikan dalam merancang kendaraan hemat energi yaitu mengurangi bobot kendaraan, mereduksi gaya hambat udara, memaksimalkan efisiensi motor atau engine dan transmisi serta pengoptimalkan operasi kendaraan. Faktor bobot pada kendaraan yang dapat direkayasa lebih mudah, memberikan hasil signifikan serta menjadi langkah awal mengoptimalkan faktor lainnya. Pemilihan jenis chassis monocoque dikarenakan chassis merupakan jenis chassis yang paling ringan dibandingkan jenis chassis lain serta penggunaan material komposit pada chassis ini dapat menjadi salah satu solusi untuk mengurangi berat pada kendaraan. Metode penelitian yang digunakan dalam penelitian ini adalah simulasi komputer memanfaatkan software Ansys 18.2. Menggunakan model tim Apatte 62 Brawijaya model urban concept sebanyak 12 model dengan variasi tebal top dan bottom skin 4 plies, 6 plies, dan 8 plies sudut orientasi 45o dan tebal honeycomb core 10mm, 15mm, 20mm, 25mm. Material skin menggunakan epoxy carbon fiber prepreg jenis woven (60% carbon). Pemodelan material yang digunakan adalah orthotropic. Pengujian yang dibuat menggunakan model pengujian statik dengan pembebanan vertical bending dan torsional. Berat driver 70 kg dan berat powertrain 30 kg. Analisis deformasi dan distribusi tegangan menggunakan Classical Lamination Theory (CLT) Laminate Stiffness Matrix. Hasil deformasi terbesar pada pembebanan vertical bending 2,75 mm pembebanan torsional 3,49 mm terjadi pada model 1 [45/45/
English Abstract
Designing energy efficient vehicle is one of the way to decrease energy consumption in transportation sector. Reducing weight, reducing drag force, optimizing the engine and transmission, and changing driving style are important factors of designing energy efficient car. Reducing weight of the vehicles is easier than other factors, because it delivers significant results and becomes a beginning step to optimize other factors. The choice of monocoque chassis type is because it is the lightest type of chassis compared to other types and the use of composite materials on the chassis can be one solution to reduce the weight of the vehicle. The method used in this research is computational simulation using Ansys 18.2. Using 12 models of Apatte 62 Brawijaya urban concept design with variation of top and bottom skin thickness 4 plies, 6 plies, and 8 plies, orientation angle 45o and honeycomb core thickness 10mm, 15mm, 20mm and 25mm. The skin material used is epoxy carbon fiber prepreg type woven (60% carbon). The material modeling used is orthotropic. The test were made using a static test model with vertical bending and torsional loading. The driver weights 70 is Kg and the powertrain weights is 30 Kg. Analysis of deformation and stress distribution using Classical Lamination Theory (CLT) in Laminate Stiffness Matrix. The largest deformation result in vertical bending loading of 2.75 mm torsional loading of 3.49 mm occurred in the 1 [45/45/
