DESCRIPTION:Precision positioning systems are more and more used in extrem
 e environments\, like deep UV light sources\, electron beams and vacuum. F
 lexure elements for guiding the motion do not suffer from the traditional 
 hysteresis and wear\, and do not contaminate. However\, they are generally
  used for small range of motion mechanisms\, because of stress limitations
  and an inherent decrease in stiffness in supporting directions when defle
 cted. \nIn this seminar several flexure-based precision mechanisms are pre
 sented along with a fast optimization flexible multibody modeling techniqu
 e. The cases are\; a two-DOF mechanism with 100 x 100 mm range of motion a
 nd natural frequencies >100Hz\, a high support stiffness\, high actuation 
 compliance hinge over a 40 degrees range of motion\, a three-DOF MEMS-base
 d stage with 200 x 200 m range of motion with integrated feedback\, and
  the effects of overconstraining in flexure-based mechanisms shown in the 
 case of an overconstrained parallel leaf-spring mechanism. \n\nDannis M. B
 rouwer received a M.Sc. degree in mechanical engineering from Eindhoven Un
 iversity of Technology\, The Netherlands\, in 1998. He received a second M
 .Sc. degree in mechatronics design from Eindhoven University of Technology
  in 2001. From 2001 to 2004\, he was with Philips Center for Manufacturing
  Technology\, as a Mechatronics System Designer. In 2007\, he received the
  Ph.D. degree in mechanical engineering from the University of Twente\, En
 schede. Dannis holds a position as assistant Professor at the University o
 f Twente\, and he is with company  Demcon Advanced Mechatronics. He serves
  as an Associate Editor for the American Society for Precision Engineering
