Pressurization Characteristics of a Piezoelectric-Hydraulic Pump for UAV Brake Systems
In this paper, a small piezoelectric-hydraulic pump suitable for the braking system of small- and medium-sized UAVs was developed. In addition, the pressurization characteristics of the pump were analyzed and performance experiments of the developed pump were conducted. To analyze the pressurization characteristics, AMESim, a verified commercial program, was used. The modeling of the small piezoelectric-hydraulic pump was carried out by subdividing it into components, including the piezoelectric actuator, chamber, check valves, and load side. The modeling validity was confirmed via a comparison of the simulation results with the performance experimental results of the produced pump. It has been found that the simulations and experiments produced similar results regarding the overall pressurization characteristics.
