110 ピエゾアクチュエータ変位拡大機構への形状最適化の適用  [in Japanese] Shape Optimization on Displacement Magnification Mechanisms of PZT Actuators  [in Japanese]

Shape optimization of displacement magnification mechanisms for piezo-ceramic actuator was examined to realize a realize a requested actuation stroke and output force simultaneously. The basic formulation to determine the shape optimization was derived using the concept of compliance for the thermal expansion. Numerical examples for simple cantilever with PZT actuator were demonstrated to design optimum configuration. The numerical results show that the properties of optimum design of displacement magnification mechanisms depended on the objective function on the optimization.
