A cross-spring flexure pivot with variable cross-section is studied in this paper, with the purpose of overcoming the disadvantages of the conventional cross-spring flexure pivot with uniform cross-section, such as axis drift and low axial stiffness. The work started with deducing the load-displacement relationship of a variable cross-section spring leaf by using the improved Awart’s beam constrained model. Then, a mechanical model of the proposed flexure pivot was established. The effectiveness of the deformation model is verified by finite element analysis. Finally, the proposed flexure pivot is compared with a conventional one, and the results show that the flexure pivot with variable cross-section has a higher rotational accuracy and a higher axial support stiffness.
