“…In the automotive field, the vehicle industry continues to improve safety technologies and strategies, ranging from passive to active forms, to enhance passenger safety [3]. The impact attenuator is an essential structural component of a formula race car since it serves as a protective shield between the driver and the surface subject to impact loads [4]. The impact attenuator is designed to absorb the kinetic energy when collision energy is converted into a deformation to protect the vital parts behind the bulkhead from damage caused by shock loads.…”

The impact attenuator is a safety vehicle system designed to absorb the kinetic energy from a collision that is converted into deformation and ensures the deceleration level acting on the human body remains low. In this paper, we propose that the impact attenuator be fabricated with used cans, which are easy to obtain. Compared to fabricating cylinders through machining and other production processes using new material, the application of used cans may reduce production costs by approximately IDR 500,000 (USD 34.50) for one attenuator structure, while the attenuator still meets the weight criterion, i.e., it has to be light to improve acceleration and fuel efficiency. As a type of metal waste product, food cans are often fabricated from aluminum and other metal alloys. These products are widely used in our lives; if they are not recycled, they can potentially pollute the environment as waste. Given these problems and considering the use of environmentally friendly materials, lightweight used cans were chosen as materials for the proposed impact attenuator design. In the initial study, the verification and validation tests of the impact attenuator shell and used cans show good agreement between the numerical and experimental impact tests. The proposed impact attenuator design under the predetermined parameters showed that used cans of aluminum 6063 series can be recommended as an alternative material in this system.

This paper presents the dynamic behaviour of a race car body impacting a rigid barrier. The amount of deformation in the front bumper area and its effect on the driver's seat are investigated. The car crash is studied at different impact angles of 0 • , 10 • , 30 • , 45 • , 60 • and 80 • . The generated elastic and plastic stress and strain fields, specifically at the front bumper and the frontal area of the driver's seat, are compared accurately. Comparing the amount of deformation in different situations shows that an increase in the angle of impact results in more plastic deformation in the bumper but less on the driver's seat instead. As the bumper neutralises the effect of the largest part of kinetic energy and inertia forces, the frontal part of car body behind the bumper is safer.

“…Even so there is limited published work on modeling Formula Student composite nose cones. There are some publications using foam [ 7 ], aluminum honeycomb filled tubes [ 8 , 9 ] and metal frustum [ 10 ] as impact attenuators. There is also a paper that models CFRP nose cones, but only compares the results against static tests [ 11 ].…”

A numerical impact study is presented on a Formula Student (FS) racing car carbon composite nose cone. The effect of material model and model parameter selection on the numerical deceleration curves is discussed in light of the experimental deceleration data. The models show reasonable correlation in terms of the shape of the deceleration-displacement curves but do not match the peak deceleration values with errors greater that 30%.
