Abstract

Flexure mechanisms allow for highly predictable motion yet often suffer from limited load carrying capacity. In this paper we propose to use a large number of parallel flexures to carry high loads. This design may then be chosen such that the load also eliminates the drive stiffness by static balance. Increased stress and buckling due to overconstraints can be avoided if the load misalignment and manufacturing tolerances stay within computable bounds. It is shown that a 20 kN load can be carried by 23 flexures over a 5 mm stroke in a 200 × 100 × 50 mm³volume.
