The aim of this paper is to design a safety barrier to protect motorcyclists using, as a basis, rubber from used tires. The increase in motorcyclist’s protection has been a constant demand of this collective in European countries for years. The designed barrier tries to respond this demand and in turn, create a new alternative for reuse rubber from used tires, thus contributing to solve the environmental problem created by this type of waste.
The standard UNE-135900 defines the test methods to assess the behavior of the safety barriers and the level of protection against impact of motorists.
It has been created a finite element model of the safety barrier in LS-DYNA to reproduce the experimental tests which are necessary for the acceptance of the protection system.
It has been used a model of the dummy that sets the standard, to which has been added a helmet. The model was validated and adjusted using test data from a previous prototype. After, several modifications to the original in order to meet the requirements of the standard are made.
The final model of the barrier shows a lower severity than the initial prototype. In view of the results, it appears technically feasible the use of rubber for the manufacture of these motorcyclists protection systems.
