Infiuence of Unloading Modes of Spring-mass-damper Models on Vehicle to Pole Collision Simulation Results
Our intention,in this brief note,is to investigate what in fiuence the viscoelastic modelsunloading properties have on modelsaccuracy of representing vehicle crash event.Two types of simple spring-mass-damper systems (Kelvin models) such underdamped and critically damped conditions are analyzed.Subsequently,two different unloading scenarios are speci fied: elastic rebound in which only the damper is an energy dissipating element and plastic collision in which the models maximum achievable displacement is at the same time its constant de fiection at the zero-force level.By comparing modelsbehavior not only in terms of their time responses but also in terms of their force-de fiection characteristics,it is concluded which of them is the most suitable to represent vehicle to pole collision.
