Magnetic-mechanical accumulator of kinetic energy

Abstract The paper focuses on the process of non-contacting kinetic energy accumulation at the dead-end positions of a reciprocating rectilinear motion with a variable stroke. It describes the development of a magnetic-mechanical accumulator that absorbs energy while the moving part is decelerating towards the dead-end position and releases the energy back to the system while it is accelerating from the dead-end position. At the same time, it enables stroke modification of a certain level with a minimal impact on the maximum force of the accumulator. With respect to the magneto-static analysis of components, the preload of the mechanical element has been set accordingly. The dynamic analysis of the system has been carried out and the prototype produced and tested on the testing rig.
