Numerical Analysis of Passive Safety of Street Lighting Posts
- Dept. of Materials Forming and Processing, Rzeszow University of Technology, Poland
One of the most important goal in designing of street lighting posts is the fulfillment of requirements of EN 12767 standard which refers to passive safety of road constructions. Lighting posts should reduced overload force when stroked by a passenger car. Experimental investigations involving real posts and cars are relatively expensive, and provide the information about passive safety of existing posts only. In numerical simulations the passive safety of various types of lighting posts might be investigated. Obtained results provide hints about possible modifications necessary to change the level of energy absorption and car passengers safety. The numerical simulation of passenger car - lighting post crash is presented in this paper. The analysis is performed by finite elements method. The dynamic explicit approach is used, which is very effective tool for solving highly non-linear dynamic problems. Original and modified octagonal and conical poles are investigated and the obtained results are compared.
