A New Design and Analysis of BUS Body Structure

Abstract

Buses are the foremost mode of road transportation. The design of the bus body depends mainly leading the performance constraint under various types of loading and operating circumstances besides those of the road conditions. the model analysis, linear static analysis and impact analysis of an articulated urban bus body, carried out with the Finite Elements Method. The purpose of this work is to simulate and forecast the structural response of the bus body in terms of stress, strain and displacement, under several loading and constraining conditions Sensitivity analyses about FEM parameters have been run, in order to achieve an adequate trade-off between computational time and results accuracy This project deals with the GFEM modeling, analyzing of important section of the bus body for the standing gravity load, acceleration, breaking load and for the impact case.. Structural modelling is completed with the help of CATIA V5, single component is created in part workbench in CATIAV5, this part is then converted to IGS file. Finite element modelling is completed in ANSYS 14.0.
