Experimental Study and Simulation Analysis on Electromagnetic Characteristics and Dynamic Response of a New Miniature Digital Valve

Abstract

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. The electromagnetic force directly determines the electromagnetic properties of the miniature digital valve. The electromagnetic force test is studied in the paper. The results of electromagnetic simulation results are basically consistent with the experimental results. The simulation model is reliable and accurate. The dynamic simulation results show that the dynamic characteristics of the miniature digital valve meet the requirements of the digital hydraulic technology. Design of the new micro digital valve is reasonable.

Development of a High-Performance Electric Pressure Regulator Applied for Compressed-Natural-Gas-Fueled Vehicles

“…Hung and Lim [12] presented a simulation study to improve the electromagnetic force of a solenoid injector, in which they changed the cross-sectional shape of the coil, thickness of the cut-off of the sleeve, and the relative position between the coil and plunger to obtain the highest electromagnetic force. The improvements of electromagnetic force based on the effects of structural parameters were also found in other studies [13][14][15][16][17][18][19][20][21][22]. The previous studies [2,[9][10][11][12][13][14][15][16][17][18][19][20][21][22] provided useful information when improving electromagnetic force in a solenoid by optimizing design parameters such as plunger shape, plunger mass, coil shape, coil turns, coil location, air gap, pole radius, and yoke thickness of the magnet.…”

Research and Development of Electro-hydraulic Control Valves Oriented to Industry 4.0: A Review

“…Figure 12(a). Yang et al [79,80] designed a miniaturized digital hydraulic valve along with valve packages. Kramer et al [6] developed a bi-stable latching valve, which is an energy-efficient alternative to mono-stable switching valves, as presented in Figure 12(b).…”

Frequency domain modeling, analysis and verification of electro-hydraulic servo steering system for heavy vehicles

“…In order to facilitate the analysis of frequency response characteristics, set the left and right tire angles coefficient e a as the arithmetic mean value, that is e a = 0:9842. The relationship between the left and right tire angles can be linearized as equation (7). In Figure 3 When the EHSSS is at small angle working condition, that is u 3 and u 3 9 are small, cos u 3 and cos u 3 9 is considered equal to 1.…”

“…It is necessary to establish the frequency domain model at first. 7,8 Due to the strong nonlinearity of the steering trapezoidal mechanism and the hydraulic power system, it is difficult to establish the system model for engineering applications. There are a lot of valuable research in building steering system model.…”
