“…In [ 11 ], a new kind of driving module of solenoid value was presented, and it could shorten solenoid responding time, reduce energy consumption, and decrease software complexity. In [ 12 ], the method of indirect adaptive closed loop control was described; this method could enable robust detection and control of closure time and hold current. In [ 13 ], the impact of different control strategies applied to driving the solenoid injector was investigated and a high correlation was found between the opening delay and the solenoid current.…”

Analysis consisting of numerical simulations along with lab experiments of interaction effects between key parameters on the electromagnetic force based on response surface methodology (RSM) has been also proposed to optimize the design of high-speed solenoid valve (HSV) and improve its performance. Numerical simulation model of HSV has been developed in Ansoft Maxwell environment and its accuracy has been validated through lab experiments. Effect of change of core structure, coil structure, armature structure, working air gap, and drive current on the electromagnetic force of HSV has been analyzed through simulation model and influence rules of various parameters on the electromagnetic force have been established. The response surface model of the electromagnetic force has been utilized to analyze the interaction effect between major parameters. It has been concluded that six interaction factors including working air gap with armature radius, drive current with armature thickness, coil turns with side pole radius, armature thickness with its radius, armature thickness with side pole radius, and armature radius with side pole radius have significant influence on the electromagnetic force. Optimal match values between coil turns and side pole radius; armature thickness and side pole radius; and armature radius and side pole radius have also been determined.

“…In the investigated case the value of the roughness of the contact armature-sleeve is σ = 0.5 µm. The calculated armature eccentricity was shown as a function of the sleeve thickness δ u and the hydraulic clearance of the armature δ h according to (3) and (1) in Fig. 2 on the left.…”

“…Most of these studies focus on the modeling, dynamic response and control method of SVs. There are lots of reports regarding finite-element approaches [1], simulation models [2] and control [3,4] of SVs as well as investigation of temperature distribution and thermal deformations inside the SV [5]. One can also find reports regarding the electromagnetic driving force of SV.…”

Most studies on solenoid valves (SVs) assumed that the armature is concentrically positioned in the sleeve. Under this assumption the transversal component of the magnetic force is equal zero. The article presents an analytical calculation model for the estimation of the armature eccentricity. Using this model the eccentricity was calculated as a function of the sleeve thickness and the hydraulic clearance between the armature and the sleeve. After finding the eccentricity also the permeance of the radial air gap was calculated. This permeance has a direct influence on the drop of the magnetomotive force in the magnetic circuit and finally influences also the axial component of the magnetic force. In the article a calculation of both transversal and axial components of the magnetic force was carried out and presented in the appendix to the article.

“…In Huber and Ulbrich (2014) a simulation model of a solenoid valve was developed and validated. The method of closed loop control for the closure time and hold current was developed in Shahroudi et al (2006) and in Lu et al (2014) the authors investigated the impact of different control strategies of the switch-on time. One popular digital technique in hydraulics is the switching technique known as the PWM method.…”

In order to estimate the inductive power set in the armature of the high-speed solenoid valve (HSV) during the open loop control (OLC) using pulse width modulation (PWM) an analytical explicit formula has been derived. The simplifications taken both in the geometry and in the physical behavior of the HSV were described. The inductive power was calculated for different boundary conditions and shown as a function of the frequency of the coil current. The power set in the armature was used as an input to the thermal calculation. The thermal calculation had an objective to estimate the time dependent temperature distribution in the armature of the HSV. All the derivation steps were presented and the influence of different boundary conditions was shown and discussed. The increase of the temperature during the heating with inductive power has been evaluated both in the core and on the side surface of the HSV.
