R&D EPAR TV

EPAR Technology is an innovative method of preventing effects of dynamic collisions between physical objects having high kinetic energy or their collisions with stationary obstacles.
The innovation of EPAR technology consists in the absorption of kinetic energy of accelerated masses during collisions which by their nature are very short. The energy is transmitted to a rotating energy accumulator which dissipates it within a selected period of time. The benefits of using EPAR are remarkable. The colliding objects are not destroyed since their energy is channeled to an accumulator which dissipates it slowly.
The fundamental principle of EPAR technology is the conversion of the kinetic energy of linear movement into the kinetic energy of a circular movement by means of a stable or changeable multiplicative transmission. The key aspect of the technology is the direct relation between the velocities: linear velocity of the decelerated mass and the angular velocity of the rotors absorbing the kinetic energy. Thanks to the multiplicative transmissions, the mass of the rotors is little and constitutes a fraction of the percentage of the object mass, simultaneously it makes it possible to put them in high angular speed which are proportionate to the needs of the decelerated object.
The performance of EPAR technology ranges depending on the system between 50% and 90%. The degree of the absorption of kinetic energy is affected by factors such as the transmission ratio, internal friction of the kinetic energy transmission systems and inertia, or the moment of inertia of the system's components.
Among the key advantages of EPAR technology one of the most important is the manner and the form of kinetic energy absorption between objects. The fact of using rotors as absorbing components enables to achieve unrivaled energy absorption efficiency during collisions. Additionally, no increase occurs in the potential energy within the systems as a form of storing the kinetic energy in the object is the kinetic energy of the rotor which enables to create systems in which the energy capacity is variable and is adequate to the energy of the retained object.
Huge benefits and advantages are to be gained over standard methods of kinetic energy dissipation (e.g. friction systems, springs, actuators, elastomers, structural deformation). For this reason EPAR systems are not limited to the range of initial parameters and in an automatic way they adapt to the colliding object, and their potential because the absorption depends mainly on the speed of the colliding objects.
Competitiveness of EPAR technology especially relating to higher safety levels, the absorption of kinetic energy, and the structure of the target devices in comparison to the present solutions are outstanding. The costs of implementing the technology and the products manufactured on its basis will be similar to its present levels and in some cases they offer the possibility of reducing material and manufacturing costs. It is possible to combine standard technology solutions with EPAR technology, which will additionally multiply the potential of physical protection of the objects against shocks or collisions.
