چکیده
The subject of this investigation is the development of an accurate simulation of a truck impacting a strong-post w-beam guardrail. Detailed methods for system simulation are proposed and three major issues which involve the use of springs to simulate component crashworthiness behavior is investigated. Rail to blockout bolt connection, soil-post dynamic interaction, and effect of ends of guardrail are modeled and simulated. Soilpost interaction is modeled using both Lagrangian and Eulerian meshes and results using the two methods are presented. The present paper provides a roadmap for simulation of highway safety structures.
