This paper examines an approach used to design adaptive systems by means of Rapid-Prototyping on the basis of a simulation. The vibration behavior of mechanical systems including actuators, sensors, and an adaptive controller in the time domain will be modeled. This approach includes the...
During the design of mechanical systems one normally exploits numerical analysis and optimization tools. We make a plea for symbolic computation and give an example where structural displacements under load are computed symbolically. Geometrical design parameters enter in this computation. The...
High strain actuation can be obtained from crystallographically textured piezoelectric ceramics. Single crystal piezoelectrics demonstrate high strain because crystal orientation can be controlled - the perfect lattice simplifies crystal orientation. Single crystals actuate better than typical...
A three-dimensional, meso-electro-mechanical model has been formulated for description of PMN-PT-BT ceramics. Unlike the experimentally fit models and phenomenological models which are based on state variables and/or empirical relationships, this fully coupled, computational mesomechanics model...
Analysis and synthesis of compliant mechanisms has recently been the subject of significant study in the research community. This focus has led to a number of design approaches for developing compliant mechanisms. This paper describes the value of using the Pseudo-Rigid-Body Model (PRBM) to...
High-field theoretical and experimental analysis of piezoelectric and magnetostrictive actuators is presented. First, the analysis of a piezoelectric stack actuator (PiezoSystems Jena PAHL 120/20) is described. A theoretical model based on the linear theory of piezoelectricity is developed....
