Abstract

The function of the frame on the electric motorcycle is to support the rider's load and where several motor components are combined, and also acts as the basic form of the motorcycle itself. The design of the electric motorcycle frame design also needs a finite element analysis. The analysis computes and produces formulas to estimate the actions that can be performed on the object, where this method involves dividing the structure into smaller elements connected by nodes or in other words, the discretization of elements. The objective of this research is to analyze the yield strength level of the electric motorcycle frame design under static loading conditions in accordance with the load safety standards of two-wheeled vehicles in Indonesia. The subject of this research is an electric motorcycle frame design with a naked bike frame type. The material used in the frame is aluminum alloy 6061 T6. The total loading during simulation is 265 kg. The quality of element discretization obtained in the electric motorcycle frame design is 0,278 with the size of each element of 5,5 mm. The maximum von Misses stress obtained is 125,3 MPa with a maximum deformation of 0,08618 mm and the safety factor is 2,154. The results of this study provide a statement that the electric motor frame design is able to withstand the load during simulation.

Abstract

Leg prosthetics as a device to increase the mobility of people with disabilities need to be supported in their development, especially in terms of comfort. Modifications to make prosthetics more comfortable to use are by utilizing the elastic properties of springs and base plate materials and dampers. This study analyzes the strength of steel and aluminium prosthetic base components in bearing the dynamic load of user's body. The analysis uses computational techniques with the finite element method. Computational results show that the most critical part of prosthetic, i.e. the base, is safe with maximum working stresses of 31,56 MPa for steel and 44,03 MPa for aluminium. Both materials are able to withstand the working stress.
