Abstract:
(EN) The shape memory alloy actuator drive device (21) is configured such that a shape memory alloy (SMA 15) expands and contracts with temperature changes and has hysteresis for distortion characteristics of parameters regarding that expansion and contraction, wherein the parameter values corresponding to the target positions of a moving part, which is displaced and driven by the expansion and contraction of the SMA (15) as the temperature of the SMA (15) rises and falls, are measured by a measurement part and set as target parameters, the crystal phase of the SMA (15) is pre-martensitic, and the temperature of the SMA (15) is caused to rise or fall so that the parameter value measured by the measurement part passes the target parameter, after which, the temperature of the SMA (15) is again caused to rise or fall so that the parameter measured by the measurement part reaches the target parameter.
(FR) Le dispositif d'entraînement à actionneur en alliage à mémoire de forme (21) est configuré de façon qu'un alliage à mémoire de forme (SMA 15) se dilate et se contracte avec les changements de température et présente une hystérèse pour des caractéristiques de distorsion de paramètres concernant cette dilatation et cette contraction, les valeurs de paramètre correspondant aux positions cibles d'une partie mobile, qui est déplacée et entraînée par la dilatation et la contraction du SMA (15) selon l'augmentation et la diminution de la température du SMA (15), étant mesurées par une partie mesure et définies en tant que paramètres cibles. La phase cristalline du SMA (15) est prémartensitique et la température du SMA (15) est amenée à augmenter ou à diminuer de façon que la valeur de paramètre mesurée par la partie mesure passe par le paramètre cible, après quoi, la température du SMA (15) est à nouveau amenée à augmenter ou à diminuer de façon que le paramètre mesuré par la partie mesure atteigne le paramètre cible.
(JA)  本発明の形状記憶合金アクチュエータの駆動回路21は、形状記憶合金(SMA)15が温度変化によって伸縮し、その伸縮に関するパラメータ-歪み特性にヒステリシスを有し、SMA15の温度を昇温または降温させる間に、SMA15の伸縮によって変位駆動する可動部の目標位置に対応する前記パラメータ値を測定部によって測定して目標パラメータとして設定し、SMA15の結晶相がマルテンサイト相になる前であって前記測定部で測定された前記パラメータ値が前記目標パラメータを通過するように、SMA15の温度を降温または昇温させ、その後、前記測定部で測定された前記パラメータ値が前記目標パラメータとなるように、再度、SMA15の温度を昇温または降温させるものである。
