ENERGY ABSORBING BARRIER FOR DYNAMIC ABSORPTION OF KINETIC ENERGY

摘要

An energy absorbing barrier, comprising a plurality of energy absorbing modules (211-217), each module comprising a casing (101) configured to receive impact energy and a rotor (102) mounted within the casing (101) and coupled via coupling means (104) with an actuator (103), the casing (101) being movable with respect to the actuator (103) such as to absorb at least part of the kinetic energy of impact imparted to the casing (101) in rotational movement of the rotor (102). The modules (211-217) being arranged in at least two serially connected sections (211; 212-213; 214-217), wherein the casing of at least one module in each section (212- 213; 214-217) is movable with respect to the casing of at least one module in the preceding section(211; 212-213) and configured to receive the impact energy not absorbed by the module of the preceding section (211; 212-213).
