“…Moreover, this research in line with Masoumi [5] reported aluminum bonnet has more displacement than steel. This means that aluminum has better crashworthiness regarding to its light weight.…”

“…Otherwise, more harder material of outer hood panel can increase the number of HIC values. Masoumi et al [5] had investigated comparison between engine hood made of composite material, steel and aluminiumin terms of material cost, manufacturing cost, maximum displacement, HIC valuesand weight. They found that the composite materials have higher material and manufacturing costs thansteel and aluminum and maximum displacement, lower HIC, and weighter than aluminum and steel.…”

“…The Head Injury Criterion (HIC) indicates a measure of the likelihood of head injury arising from an impact, which is evaluated by the impactor in terms of the simulation of child head. HIC includes the effects of head acceleration and the duration of the acceleration [5]. The impacts of standard child headform on nine different designs have been simulated in this study.…”

Traffic accidents are terrible scourge that occur in many countries, specially for developing countries where transportation affairs like tangled yarn. Besides functioning as an engine compartment cover, the hood of modern compact SUV can also help to manage the impact energy of a pedestrian’s head in a vehicle-pedestrian impact. This paper presents outer hood design of Esemka R2 that has a potential to improve hood’s ability and also to absorb the impact energy of a pedestrian’s head. The developed method for the design of an outer hood configuration aims to provide a robust design and homogeneous of Head Injury Criterion (HIC) for impact position at WAD 1000 and three different thicknesses (1.25 mm, 1.35 mm & 1.50 mm) of outer hood panel of Esemka R2 compact SUV, taking into consideration the limited space available for deformation. The non-linear Finite Element Analysis (FEA) software (Explicit Dynamics) was used in this research to simulate the testing procedurs of head impact for child pedestrian. The results show that the average of comparison dimensional of outer hood panel of Esemka R2 was 4.89 mm. The minimum of deformation space meet the requirement for HIC value which required obtaining robust and homogeneous head impact performance. Outer hood thickness and materials were identified as the factors to influence the stress and HIC value of the hood. By comparing all outer hood panels, aluminium alloy as the best selected material which has the lowest value is 32.78% for the pedestrian protection.

“…Elements associated with crash protection have to be compelled to transmit or absorb power. Carley ME et.al [8] observes is to layout inexperienced epoxy structural foam reinforcements to boost the energy absorption of the front and rear automotive bumper beams. 3 bumper structural overall performance criteria had been studied.…”

An automobile’s bumper is the front-most or rear-most part, ostensibly designed to allow the car to sustain an impact without damage to the vehicle’s safety systems. They are not capable of reducing injury to vehicle occupants in high-speed impacts, but are increasingly being designed to mitigate injury to pedestrians struck by cars. The automobile bumper weight is reduced by the utilization of composite and high- strength gilded sheet of a skinny material. Once the motor vehicle is hit from the front or behind, the bumper beam collapses. The impact force is transmitted to the left and right front frames on the bumper beam and bumper stays. The impact energy created throughout the crash is absorbed by plastic deformation on the bumper beam and bumper stays that square measure the specified elements of bumper For characteristic the foremost effective material, varied analysis like static analysis, impact or crash analysis, dynamic and modal analysis area unit required the target of the work is to counsel the foremost effective material for bumper that is ready to ensure rider safety, with high strength to weight quantitative relation through the static and dynamic analysis.

“…Masoumi A et.al [11] in their thesis describes the design of a new frontal vehicle structure that directs the asymmetric crash load of an offset collision as an axial load to the second unloaded longitudinal member. Only by using both longitudinal members and through a progressive folding pattern, enough energy can be absorbed in the front structure to prevent a deformation of the passenger compartment.…”

Car accidents are happening every day. We must take into account the statistics – ten thousand dead and hundreds of thousands to million wounded each year. These numbers call for the necessity to improve the safety of automobiles during accidents. Automotive bumper system is one of the key systems in passenger cars which helps to protect the vehicle during impacts. The following paper deals with the design improvements in the front bumper of passenger cars in India, using impact analysis. The modification will be made considering size, shape and material.
