Numerical investigation of Belleville spring as an energy absorbing component

Crashworthiness research has attracted significant attention, focusing on evaluating deformation behavior and selecting composite material components that act as energy-absorbing devices. Among the available composite materials, carbon fibers can absorb high energy during a crash. This paper presents the initial concept of the design application of a carbon fiber Belleville spring. The proposed design of the mechanism is directed to reduce the extent of the impact. An analytical approach is followed to calculate the energy absorbed during a crash. The parametric study is conducted for a different range of load [Formula: see text][Formula: see text]N to predict which spring material absorbs maximum energy. The impact on the occupant side is minimum by the finite element approach. A brief overview of the spring’s energy absorption capability is provided through Ansys, and a correlation is proposed, which helps predict the value of Energy for different loads.
