Model studies concerning the assessment of soldiers’ safety are mainly focused on the examination of vehicle construction and designing energy consuming materials that reduce acceleration pulse affecting soldiers during an explosion. Authors of this paper focus on ergonomic factors that have a significant impact on the safety of the soldiers during the explosion of improvised explosive devices (IED) under the vehicle. The study examined the impact of the equipment carried by the soldiers on the injuries incurred by them. The research was conducted in the Madymo software program. Simulations indicate a high risk of serious head and neck injuries caused by a wrong weapon position.

In this paper an approach of optimization of suspension system parameters is described. Taking into consideration the sti?ness and damping coe?cients of springs and shock absorbers of a heavy road transportvehicle semitrailer, process of adjusting those values has been undertaken by means of the response surface methodology and a desirability function application, supported by the sensitivity computations. Twodifferent methods of constructing metamodels: Kriging and polynomial regression have been tested andcompared with a set of results obtained from the numerical multibody dynamic analysis. The objectiveof the undertaken efforts was to minimize the loads in the crucial points of the structure, identi?ed as the high-risk failure areas. A number of simulations have been carried out under the set of di?erent load cases, specially established to represent a wide range of operating conditions possible to be met during the vehicle life cycle.
