By rearranging the flexure formula, the maximum moment that may be applied to the beam cross section, called the. : Cite journal requires |journal= ( help) "Eliminating Underconstraint in Double Parallelogram Flexure Mechanisms". Additionally, special care must be taken to design the flexure to avoid material yielding or fatigue, both of which are potential failure modes in a flexure design.
This makes flexures a critical design feature used in optical instrumentation such as interferometers.ĭue to their mode of action, flexures are used for limited range motions and cannot replace long-travel or continuous-rotation adjustments. The stress pattern due to flexure then depends upon the location of the. Examples on quasiuniform stress states, admitting exact solution, were studied. for the solution of problems in the Mechanics of Materials is the finite. Flexures are able to achieve much lower resolution limits (in some cases measured in the nanometer scale), because they depend on bending and/or torsion of flexible elements, rather than surface interaction of many parts (as with a ball bearing). Mechanics of composite materials with a small-scale structural flexure. Problem 526 A wood beam 6 in wide by 12 in deep is loaded as shown in Fig. Additionally, conventional bearings or linear slides often exhibit positioning hysteresis due to backlash and friction. High precision alignment tasks might not be possible when friction or stiction are present. A few examples are shown in the text book to illustrate how this is done where the nails are designed to transfer the total shear force between web and flange. Examples of anisotropic materials, whose properties are different in. In the field of precision engineering (especially high-precision motion control), flexures have several key advantages. Therefore, the subject of mechanics of materials or strength of materials is. Using compound flexures, complex motion profiles with specific degrees of freedom and relatively long travel distances are possible. Since single flexure features are limited both in travel capability and degrees of freedom available, compound flexure systems are designed using combinations of these component features.
