The paper deals with numerical methodologies to improve the operationability and survivability of armoured vehicle subject to mine explosions. Methods are proposed to model and extract the time history of the impulsive load from a mine explosion, and to restore equivalent loading conditions to a structural analysis calculation. The problem of computing the shock transmitted to the floor through the undercarriage in the case of the explosion of a mine under a wheel is finally investigated. That kind of model enables to discriminate whether the highly dynamic shock is transmitted through the wheel/undercarriage, or directly through the floor.
