“…Large stroke high precision positioning system in many professional fields has become a key micro-material processing and manufacturing. For example, nanoimprinting film technology as another new concept of nanostructures and new manufacturing processes, in the preparation of nano-electronic components, biotechnology or micro-chemical materials nano-silicon laboratory, micro-optical elements, fuel cell systems and nano-magnetic storage devices and other technical fields play an extremely important role [4][5]. Because of its very small operating object, the requirements for the stroke, speed and accuracy of the equipment are also more stringent [ 6 ].…”

With the continuous development of manufacturing technology, ultra-precision machining, precision instruments, semiconductor manufacturing and biomedical engineering, precision positioning technology based on piezoelectric ceramics has been widely used in industrial production, weaponry and scientific research. It is one of the most important technologies to support the development of equipment to high precision, high efficiency and intelligence. However, the precision positioning system is difficult to meet the requirements of large stroke and high precision. Aiming at this problem, a large stroke piezoelectric linear motion platform based on piezoelectric drive is developed. In order to detect the source of error, a high-frequency response and non-contact yaw error detection system combining flat ruler and capacitive micro-displacement sensor is designed, and an error detection method is established. At the same time, in order to compensate the error, a micro-motion error compensation platform based on piezoelectric ceramic drive, elliptical amplification mechanism and flexible dumpling chain drive is designed, and experimental research is carried out. The results show that the proposed method in this paper can compensate the system error, and has good dynamic characteristics, which meets the positioning accuracy required by precision equipment.

The electromagnetic servo steering gear commonly used in the modern small guided aircraft has parasitic electromagnetic fields that affect the navigation and guidance accuracy, and its deceleration mechanism will increase the volume and mass, and the operating temperature range of the electromagnetic steering gear is small. A recently developed piezoelectric linear displacement accumulating high-power density actuator can solve those problems effectively. A virtual prototype model of piezoelectric linear displacement accumulating high-power density actuator is established, and the reliability of the virtual prototype model is verified by comparing with the experimental data. In order to make the actuator with the lightest weight under the requirements of wing deployment, Isight and Adams co-simulation were used to optimize the parameters of the piezoelectric actuator, such as the outer diameter, length, and excitation frequency. Finally, the output power of 50.8 W/kg is achieved, which is comparable with the power density of the existing servo motor.
