The dynamic behavior of two different micro valves was measured by Luharuka et al. Effects of electronic circuit on the magnetic field of a solenoid valve were studied by Angadi. Through selection of different soft magnetic materials and structure parameters, larger magnetic force and lower power losses have been achieved by Tao et al.

How to obtain largest electromagnetic force in a smaller size is a key problem, which should be given more attention.Ī large number of working mechanisms of electromagnetic characteristics of the high-speed valves have been studied. Electromagnetic force decides the response performance of the micro high-speed digital valves. Fast response performance of the micro high-speed digital valves directly influences the control precision of the whole system. In addition, the micro high-speed digital valves are the key components of the digital hydraulics system. Therefore, the size of a single valve should be designed to be smaller to solve the problem.
Because the digital hydraulic system is composed of many digital valves, the size of the system is bigger than that of the proportional system and the servo system. Introductionĭigital hydraulics technology has a potential to replace the proportional technology and the servo technology because of their superior properties, such as low cost, reliability, and insensitivity to contamination. Design of the new micro digital valve is reasonable. The dynamic simulation results show that the dynamic characteristics of the miniature digital valve meet the requirements of the digital hydraulic technology. The simulation model is reliable and accurate. The results of electromagnetic simulation results are basically consistent with the experimental results. The electromagnetic force test is studied in the paper. The electromagnetic force directly determines the electromagnetic properties of the miniature digital valve. In order to get the better electromagnetic characteristics of the micro digital valve, the larger electromagnetic force should be obtained in the smaller electromagnetic structure.
