Modal and Stress Analysis of X71A Sport Motorcycle Framebody Virtual Testing Model based on Finite Element Analysis

摘要

The X71A framebody is new model development of sport chasis motorcycle, designed for two pasangger vehicle. 3D CAD geometry is modeled using CATIA V5R22. Two 3D CAD model geometry using weld bead and without weld bead was built to get updating FEA model. SimDesigner V2015 is used to generate 3D solid mesh. These two both model were meshed with various mesh size. Finite Elemen Analysis was used to solve the modeling and simulation. Modal analysis of X71A framebody model was done using Msc Nastran 2014 SOL 103 normal mode solution to obtain eigenvalue and eigenvector. The frequency response analysis is performed using Msc Nastran 2014 SOL 111at 2G with range frequency 1-100Hz. Boundary constraint was used represent the actual condition. The load was given at the center of front and rear axle position using RBE2 element. Using frequency response analysis, 1st mode at 3Hz dominant frequency of framebody shown stress distribution at the resonance condition and used to determine strenght acceptable of the framebody. The use of FEA test model is very helpful to avoid trial and error at the development stage.
