Sažetak
Compliant mechanisms have several advantages in terms of low friction, maintenance and backlash over traditionally used rigid body mechanisms. Those advantages are especially important in applications of nanometre positioning and manipulation, commonly required in a field of micro and nanometrology. In these fields linear stages are one of the main applications of compliant mechanism. Traditionally, linear stages are produced in simple 2-dimensional forms using different cutting techniques. In the recent years compliant mechanisms are getting more commonly produced using additive manufacturing, which provides possibility of usage more complex geometries with superior mechanical characteristics. This paper explores different shapes of compliant hinges that couldn’t be produced using traditional manufacturing techniques but can be produced using additive manufacturing. Four variations of hinge geometry were introduced. In order to compare mechanical properties, CAD models with variations of these four designs has been created. Using FEM simulation horizontal and vertical displacements of these mechanisms were tested in order to calculate their ratio and overall efficiency of the mechanism.
