Research on Establishment of Application Method of Impulsive Force Generated by Multilayer Piezoelectric Actuator

为了扩大多层压电致动器的应用领域，目的在于建立利用当电压被快速施加到元件时产生的冲击力的技术。首先，制作了步进运动机构。连续的冲击力作用在由弹簧支撑的质量上。该机构利用惯性力和摩擦力的差运动。并对其行驶特性进行了研究。接下来，制造了通过使用元件的快速膨胀来喷射少量流体的喷射泵。作为射流泵的一个应用，设计了一种管道内流动颗粒的分选器，并对其分选特性进行了研究

In order to expand the application field of the multilayer piezoelectric actuator, it has aimed to establish the technology that uses the impulsive force generated when the voltage is rapidly impressed to the element. First, a stepwise motion mechanism was made. Successive impulsive force is acted on a mass supported with a spring. The mechanism moves using difference between inertia force and friction force. Its driving characteristics were examined. Next, a jet pump that ejects a small amount of fluid by using a rapid expansion of the element was made. As an application of the jet pump, a sorter of the particle that flowed in the conduit was designed and its sorting characteristics were examined
