The EXPLICIT DYNAMIC ANALYSIS OF AUTOMOTIVE BUS BODY STRUCTURE DURING CATASTROPHIC FRONTAL CRASH WITH EXPULSION SYSTEM

Abstract

Investigation of accidents for buses and Automotive, Accidents involved frontal crash creates a vital portion among all bus accidents. Through this sort accidents, front body of the bus structure gets severely damaged and this will lead drivers and crew injury risk. And most of the frontal crash accidents ends up with the death of the driver. As a result of this, the protection of the driver and crew ought to be ensured within the case of frontal crash accidents. Providing the safety of the driver is crucial, since bus driver is a key person for keeping the control of the bus within the event of accidents, safety of the passengers are going to be ensured. Usually the bus structures are developed in consideration of less weight, efficiency and safety. Due to fragile structure it causes a more damage during an accident. Thesis proposes a new method for designing a bus body structure in 3 Dimensional modelling software creo-3.0. Finite Elemental Method and Ansys Software are being used to analyse crash simulations. The nonlinear dynamic explicit finite element method is used to establish the frontal crashworthiness model of vehicle, the finite element model is consistent with vehicle improving stiffness. The result analysis of Dynamic simulation calculation and Boundary condition of front crash is processed to a particular bus chassis model, which improve the front crash safety performance the safe ejections of passengers. In This Proposed thesis, result analysis are carried in three type’s
Numerical and Simulation method. Experimental method is analysed in Scale module bus chassis and structure stiffness is examined by the Simulation analysis. It is vital important role so to understand the Dynamic impact load Analysis are which are examined in Ansys/ Finite Elemental Method software.
