Simulation Models for Compliant Mechanisms with Integrated Actuators

The transmission of motion sequences is currently realized in most applications by classica l mechanisms with a lot of parts and high structural weight. Using compliant elements with specific adjustable compliances it is possible to transmit m otion just by structural deformations. Moreover, the comp osite may integrate piezo-ceramic actuators into the lami nate lay-up and thus offers the opportunity to design structure-integrated drives. However, the actual mo tion of the system can be obtained with the desired accu racy only after tests and re-design, implying high costs and consuming precious time. This paper makes a contribution to the compliant structure simulation, by developing some kinematical simulation models with active prismatic joints and rotational joints with concentrated torsion rigidity, able to predict the actual motion of compliant mechanisms with integrated piez o- ceramic actuators.
