Scientists from Rzeszów building kinetic energy absorber
In construction and civil engineering, it will be used to protect the structure of buildings, in architecture - to protect elevator users during failures, and in astronautics - in landers to protect the suspension vehicle's during landing.
The scientists are working on an absorber that will absorb kinetic energy and dissipate it during collisions and impacts with high force and speed, especially in the case of speeds above 20 m/s. Dissipation of energy is the transformation of macroscopic ordered energy associated with motion into energy chaotically distributed over many degrees of freedom, most often the energy of thermal motion of particles.
Research team leader Dr. Igor Labuda from the Faculty of Civil and Environmental Engineering and Architecture of the Rzeszow University of Technology, said: “Our goal is to develop an absorber that will be used to protect vehicle users and building structures. The device can be used together with other protection measures, including crumple zones, to protect passengers and vehicles during collisions.”
Research shows that currently there are no known technologies that would enable obtaining a constant level of kinetic energy dissipation over the entire braking distance at an impact velocity exceeding 20 m/s.
Dr. Labuda said: “Optimal use of the available braking distance is particularly important during accidents, because excessive overload or underload is the main reason for internal injuries. They often lead to death.” Read More…
