Abstract

A novel design approach making use of purely elastic magnet modules based on Halbach arrays for hybrid midsole constructions is proposed. Recovery of the surrounding midsole material after compression may thus be supported. In order to overcome challenges induced by the properties of ferromagnetic materials specific design principles had to be developed and implemented. In particular, mechanical guidance of the magnetic elements in vertical direction had to be ensured. FEM simulation has been applied in order to identify practicable geometrical arrangements of the magnets. Sufficient guiding accuracy was achieved by developing an effective structure utilizing dual Halbach arrays pivoted at a flat angle to one another using a common axis of rotation. Prototypes of midsoles and running shoes which utilize the novel technique have been manufactured. Validation tests revealed significantly higher stiffness of the modified midsoles and a reduced spring deflection. Biomechanical tests of the modified running shoes are in progress.
