“…Optimization of the control cone parameters such as D, t, and P is important to achieve consistent linear characteristics of the plunger movement with respect to the control input given to the solenoid. Analysis of various designs for the computation of force on the plunger is performed by Finite Element Method Magnetics (FEMM) software application [2], [7], [10] The details of mesh settings are as shown below…”

“…Even though design of proportional solenoids with different configurations is possible with multiple parameters that can be optimized, the given solenoid is designed with the configuration as shown in Fig 2, and optimized for the three independent variables namely D, t and P. Each step in the recursive method finds the optimal location of an individual parameter in coarse search that narrows down to a fine search in the subsequent iterations. The optimization of the cone parameters of the proportional solenoid is based on minimizing the objective function f(s) [2], [6], [10] shown below:…”

Proportional solenoid valves are used in various applications that require smooth control of flow or pressure. Manufacturing such valves would involve design of valve component, solenoid core and the coil for specific input and output ratings. Materials for each component of the solenoid valve need to be selected for their magnetic properties, application specific requirements such as medical grade, temperature compatibility, etc. With proportional control as the primary objective, the proportional solenoid valve must exhibit linear characteristics between the control input and the output. Optimization of the magnetic core plays a vital role in achieving these requirements. Optimizing the core geometry of the proportional solenoid is crucial in achieving necessary linearity in the plunger movement without compromising the actuating force on the plunger for a given size of the solenoid. A proportional solenoid valve for mass flow control in low pressure application such as medical oxygen ventilators is developed based on the performance requirements such as flow rate, pressure and control requirements such as the solenoid voltage and current ratings. The materials used for manufacturing the valve components such as medical grade stainless steel with required magnetic properties are selected based on the application requirements. An optimization technique based on recursive method is used to determine the efficient core geometry for a proportional solenoid valve. The experimental results obtained from the proportional solenoid valve manufactured based on optimization results closely matched with the calculated values of plunger displacements from different offsets of 0 mm, 1 mm and 2 mm from the reference position in a total stroke length of 5 mm, which is presented in this paper.

“…NURBS are a very general way to represent geometries and widely used in CAD systems. Therefore, it seems natural to use the control points (and weights) of NURBS curves as design parameters [6,48]. This approach has received considerable attention in recent years as new approaches, incorporating NURBS geometries into FE analysis, have emerged.…”

Robust shape optimization of electric devices based on deterministic optimization methods and finite-element analysis with affine parametrization and design elements

In this paper, gradient-based optimization methods are combined with finite-element modeling for improving electric devices. Geometric design parameters are considered by piecewise affine parametrizations of the geometry or by the design element approach, both of which avoid remeshing. Furthermore, it is shown how to robustify the optimization procedure, that is, how to deal with uncertainties on the design parameters. The overall procedure is illustrated by an academic example and by the example of a permanent-magnet synchronous machine. The examples show the advantages of deterministic optimization compared to standard and popular stochastic optimization procedures such as particle swarm optimization.

A novel reliability calculation algorithm is developed and applied to a robust optimization of electromagnetic device with uncertain design variables taken into account. The proposed algorithm, to calculate the reliability of a given design, incorporates sensitivity analysis based on finite element method with Monte Carlo simulation (MCS) method so that it has higher numerical efficiency than conventional methods: MCS and first-order reliability methods. Through numerical examples, its applicability to a reliability-based robust optimal design of electromagnetic device is demonstrated.
