Shape Optimization to Minimize The Response Time of Direct-acting Solenoid Valve

Abstract

Direct-acting solenoid valves are used in the automotive industry due to their simple structure and quick response in controlling the flow of fluid. We performed an optimization study of response time in order to improve the dynamic performance of a direct-acting solenoid valve. For the optimal design process, we used the commercial optimization software PIAnO, which provides various tools for efficient optimization including design of experiments (DOE), approximation techniques, and a design optimization algorithm. 35 sampling points of computational experiments are performed to find the optimum values of the design variables. In all cases, ANSYS Maxwell electromagnetic analysis software was used to model the electromagnetic dynamics. An approximate model generated from the electromagnetic analysis was estimated and used for the optimization. The best optimization model was selected using the verified approximation model called the Kriging model, and an optimization algorithm called the progressive quadratic response surface method (PQRSM).

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.…”

Investigation on Electromagnetic Models of High‐Speed Solenoid Valve for Common Rail Injector

“…As shown in Figure 7, with the increase of 2, the fitting curve and experimental data match more and more closely in the initial stage of magnetization. When 2 is 0.0009, (14) can particularly accurately describe the initial magnetization process of the magnetic material. However, since 1 is not introduced to limit the maximum magnetic induction intensity, the predicted saturation induction density will increase with 2: It can be observed from the above analysis that the two coefficients 1 and 2 should be introduced to accurately describe the -fundamental magnetizing curve in (12).…”

“…It was discovered that solenoid valves with different soft magnetic materials have different characteristics of electromagnetic force. Miller et al [13], Shin et al [14], and Bianchi et al [15] carried out optimization research on the static electromagnetic force of an HSV to obtain the optimal structure parameters by FEM. However, because of the long solution time and high requirements for computer performance of FEM, the efficiency of research on the optimization and analysis of the structural parameters is low, especially when carrying out an iterative structural analysis for the detailed parameter design of HSV.…”

Modeling and Dynamic Analysis on the Direct Operating Solenoid Valve for Improving the Performance of the Shifting Control System

“…The control accuracy of the magnetic force could be well improved based on the studies. Yujeong Shin et al [5] adapted Ansys Maxwell electromagnetic analysis software to model the electromagnetic dynamics and selected the best optimization model using the verified approximation model. However, the dynamic characteristic of the valve could not be adequately enhanced if we only study the magnetic force because a sensitive pressure response is caused by the interaction of the resultant force.…”
