Abstract
This article studies the constant force characteristics of a new type of adjustable force quasi-zero stiffness mechanism that creates a constant force over a 40 mm stroke length. 3-D finite element analysis modelling is used to determine the geometric parameters that improve force uniformity. The presented constant force mechanism is shown to be capable of operating with a 7.0J/kg energy density and a peak magnetic shear stress of 101kN/m2. The constant force magnitude can be adjusted by rotating the inner rotor relative to the outer translator, the force adjustment torque is maximum when the force is zero, and when the translator is centered the torque required to adjust the force is zero. Both a 4 pole-pair and an 8 pole-pair magnetic constant force mechanism is studied.
