Optimum design of dynamic response in automotive solenoid valve

Analysis and Design of a Permanent Magnet Bi-Stable Electro-Magnetic Clutch Unit for In-Wheel Electric Vehicle Drives

“…The design and analysis of linear electromagnetic devices, such as electromagnetic valves [21], electric tools [22], oscillators [23,24], and switch gears [25][26][27], are mainly carried out by the finite element method (FEM). Likewise, aiming to satisfy the need to accommodate the clutch in the limited space available in the hub, the optimal design of the main structure parameters of the PMBECU are carried out by FEM which focuses especially on investigating the leakage flux coefficient of the PM.…”

Development of a high-speed solenoid valve: an investigation of the importance of the armature mass on the dynamic response

“…If some effects are not significant at some times, at other times they contribute significantly. Authors like Smith-Spinweber (1980), Karidis-Turns (1982), MacBain (1985), Kushida (1985), Pawlack-Nehl (1988), Lesquesne (1990a), Yuan-Chen (1990), , Ohdachi et al (1991), Kajima (1992 and, Passarini (1993), Rahman et al (1996), Ando et al (2001), Szente-Vad (2001) and Passarini-Pinotti Jr. (2003) diverge when describing the armature movement of the of the EFI and as to which of the above mentioned phenomena should be considered and which should be neglected. It seems that most of these authors consider it sufficient to calculate precisely the magnetic force attraction, F mag to accurately define the armature movement because basically their mathematical model is described by only three forces, magnetic, elastic (Hook's law) and viscous as shown in Eq.…”

Potential Viability of a Fast-Acting Micro-Solenoid Valve for Pulsed Detonation Fuel Injection

“…Further, it is only recently that the dynamic behavior of solenoid valves has received comprehensive treatment, and few definitive works have been published. [4][5][6][7] developed a robust analytical model which can be adapted to most solenoid valve geometries. The model included the effects of core losses and flux leakage However, experimental data and some parameter estimation are still necessary to completely characterize a valve's response.…”
