A non-prismatic beam element for the optimization of flexure mechanisms

摘要: Flexure joints are rapidly gaining ground in precision engineering because of their predictable behavior. However the range motion flexure is limited due to loss support stiffness deformed configurations. Most common consist prismatic leaf springs. This paper presents a simple non-prismatic beam formulation that can be used for efficient modelling The resulting and stress computed by element compared results finite analysis. shows two typical increased up factor 1.9 using instead
