Metallic energy-absorbing inserts for Formula One tyre barriers

Effect of Corner Bluntness on Energy Absorbing Capability of Non-circular Metallic Tubes Subjected to Axial Impact

The energy absorbing capability is one of the most important aspects of crushing behavior of a structure subjected to axial impact. In this paper, a simple practical method is introduced to enhance the crushing behavior of this kind of structure. The axial impact of metallic energy absorbing thin-walled tubes with special shaped cross-section is simulated using LS-DYNA software. The effect of c...

Axial Crush of Metallic and Hybrid Energy Absorbing Thin-walled Tubes with Polygonal Cross-sections: Numerical Analysis

Material properties and geometry are two important design parameters which their effects should be considered in a crashworthiness analysis. In this paper, the axial impact of metallic and hybrid energy absorbing thin-walled tubes with poly-gonal cross-section is simulated using LS-DYNA software. The combined effects of changing the geometry and material properties on the mass specific energ...

Tyre labelling for energy - efficient and quieter road transport

Analysis of Multi-transmitting Formula for Absorbing Boundary Conditions

In this paper, we analyze the multi-transmitting formula (MTF) proposed by Liao et al [19]. From the computed reflection coefficients for the fully discrete MTF boundary conditions, we suggest choices for the artificial wave propagation speed, which are different from Liao’s original choice. Theoretical and numerical studies for various incidence angles demonstrate that the suggested choices ef...

Optimal control of Formula One car energy recovery systems

The utility of orthogonal collocation methods in the solution of optimal control problems relating to Formula One racing is demonstrated. These methods can be used to optimise driver controls such as the steering, braking and throttle usage, and the optimisation of vehicle parameters such as aerodynamic down force distributions. Of particular interest is the optimal usage of energy recovery sys...
