Statics analysis and optimization design for a fixed-guided beam flexure

This paper presents a static analysis and parameter optimization for the xed-guided beam exures via using the pseudo-rigid-body model and a fmincon algorithm. The Finite Element Method (FEM) of the xed-guided beam also has been used to verify the maximum stress and the x−direction displacement. Modi ed pseudorigid-body model (M-PRBM) is also applied to signi cantly enhance the accuracy of the maximum stress value. The results show that the averaged errors of maximum stress between MPRBM and FEM are 3.48% for aluminum, and less than 10.9% for titanium, carbon steel, and alloy steel. From the obtained results, the MPRBM is good for prototype design and fabrication of ratchet mechanism in the future.
