Modelling and Analysis of an Automotive Bumper Used for a Low Passenger Vehicle

Abstract

Automotive design with economy, safety and aesthetics have been a great challenge to design engineers. Augmenting to these factors today environment impact is an upcoming research area. The safety of the passengers during vehicle crashes can be ensured to a certain limit by using good bumpers. At the same time these automotive parts should not be massive in terms of weight contributing to the increase in total the weight of the vehicle. In this work, a bumper used for low passenger vehicle, Ambassador car is modelled by using the software CATIA V5R18. Then this model is imported into FEM package of ABAQUS 6.10 impact as well as static analysis. Again modal analysis and analysis under dynamic loading done for the same model using ANSYS Workbench 11.0. The materials used for these analyses are Aluminum B390 alloy, Chromium coated mild steel and carbon composite. During static analysis, Carbon composite shows the lowest deformation and maximum von mises stress value. After the impact analysis, the composite shows the highest stress value, lowest deformation and the lowest strain value on compared with above materials. The analysis under the dynamic loading shows this carbon composite has the maximum stress value and it having the highest strength to weight ratio and producing low deformation. From all these analysis, it can concluded that carbon composite is the best material which can use as the bumper material among all the other materials used here.

RETRACTED: The Review of Carbon Fiber Materials in Automotive Industry

“…Carbon fibres can be used in various parts of vehicle. The carbon fibre reinforced composites are used in bumpers due to its improvement in strength and appreciable reduction in weight and size of frame [7]. A study done by P Kumar [8] on automotive bumpers for three different designs such as basic bumper design with steel, with the attachment of foam, and with the attachment of honeycomb which shows a higher strength to weight ratio than steel.…”

Experimental investigation and crashworthiness analysis of 3D printed carbon PA automobile bumper to improve energy absorption by using LS-DYNA

“…If e < 1, which indicates that the total energy reduces because of artificially energy is absorbed, either by excessive hour-glassing or during stabilization of an colliding contact surface. 36–39 Generally, energy ratio simply is different from unity, and then there are high probability FE results to contain errors. Since it is difficult to obtain energy ratio equal to unity so, the acceptable value of the ratio is 1.00 ± 0.07 the discrepancies in the ratio are due to spurious energy produced in the system and simulation error.…”

Composites for electric vehicles and automotive sector: A review

“…In several vehicle parts carbon fibres find their application. In view of enhancing the strength and considerable weight reduction and frame size, carbon fibre reinforced composites are employed [63]. Isaiah [64] recommended that in order to achieve noteworthy reduction in weight of vehicle by around 60%, steel should be substituted with CFRP composite.…”
