Comparison of the value of passive safety coefficients for car crash with lighting column made of aluminum or composite material based on numerical simulation

摘要

Numerical simulations have become more and more important in recent years for the design of supporting road equipment structures. These structures are important for ensuring the proper level of passive safety for drivers and passengers. These structures also allow the reduction of costs of entry for new products on the market and reduction of the total cost of production. In this paper was shown comparison of passive safety coefficient ASI and THIV for lighting column made of composite material and aluminum based on experimentally verified numerical simulation. FEM was used to carry out the simulation which was implemented in LS Dyna to determine passive safety coefficients, whose algorithm was written in MATLAB. Authors presented parameters of numerical model of the car and lighting column with the ground. The accepted boundary and initial conditions were chosen in order to show the behaviour of the lighting column during a collision with a car.
