EN Damping and energy-consuming elements can be found in many technical applications. This means these component types can prevent fractures or injuries in the case of products or people, respectively. In the last time, many modern applications and inventions associated with the reduction of the effects of an impact are observed especially in the mode of transportation safety area. The significant development of the automotive industry, increasing popularity of motorbikes, electric bikes and scooters, sports field, etc., require new solutions for personal safety protection. Human head and neck protection, and other body parts protection are typical groups of solutions from biomechanics and mechanical engineering. Authors have investigated LDPE-made pneumatic absorbers under axial impact force. Based on the experimental approach and analytical model, mechanical characteristics are presented. Impact force value, deceleration and damping for different loading conditions are shown. Because safety systems’ impact protective features can be matched to impact conditions, results indicated that absorber damping could possibly be a good solution for them, shaping the impact characteristics according to safety requirements.
