This study deals with simulation Finite Element Analysis (FEA) model of the electric scooter frame under variable load conditions done both with first order elements and second order elements and the comparison and optimization using Numerical modeling.The objective of the thesis is the design, analysis and optimization of frame of the electric scooter, computing the structural analysis of the system using Altair Hypermesh®, Optistruct®, considering both first order and second order elements and verifying them using Matlab. A maximum passenger weight of 100kg is used to determine the deformations on the frame. A study of variable loads with different numbers of loads in about 20 locations in the frame has been done.
