摘要

提出了一种新型的驱动器驱动的粉末输送系统。它有两组压电陶瓷堆，两组压电陶瓷堆的振动耦合在一起，使粉体输送管产生椭圆振动。在管壁上的粉末会被抛起，引起粉末与管壁之间的相对运动，从而被输送。为了获得更高的传输效率和速度，采用了位移放大器。对整个系统的运动进行了理论分析和讨论，并建立了数学模型。通过仿真分析，得到了输入电压与输出转速之间的关系。为进一步研究和实际应用提供理论基础。

A powder transport system based on piezoelectric ceramic stack actuators

A novel actuator-driven powder transport system is proposed in this paper. It has two sets of piezoelectric ceramic stacks whose vibrations couple together and make the powder transport pipe do elliptical vibration. The powder on the pipe wall can be thrown up, leading to the relative motions between the powder and pipe wall and thus the powder is transported. To get higher transport efficiency and speed, a displacement amplifier is adopted. The movement of the whole system is analyzed and discussed in theory and the mathematic model is established. The relationship between the input voltage and the output speed is obtained by means of simulation analysis. Theory foundation is provided for further study and practical application.
