Optimization of an axisymmetric linear electromagnetic valve actuator

In this study, an unsymmetrical bistable multi-magnetic circuit permanent magnetic actuator is proposed. The operating principle and mathematical model of the high-voltage circuit breaker with the proposed machine are analysed. Additionally, the static and dynamic characteristics of the high-voltage circuit breaker with the presented machine are investigated and evaluated using numerical finite element analysis methods. Furthermore, the influence of the length of the middle gap and the additional coil in the proposed machine are studied. The advantages of the presented machine, such as less magnet volume, low cost, high force density, and short starting time, are discussed. Finally, a prototype is created and tested, followed by the retrieval of the characteristic curves of the holding force to confirm the proposed design.

An optimization procedure based on the dynamic characteristics of a submersible electromagnetic actuator constrained in a specific volume has been developed. In order to achieve the minimum response time and low vibration when the actuator is opened, five radial dimensions are optimized when the main limiting quantity is the maximum allowed temperature. Three models, including a thermal model, an electromagnetic model, and a mechanical model are constructed, and optimization calculation is performed by using Matlab/Simulink software. According to the optimization results, an actuator is manufactured and dynamic experiments are performed. The results show substantial agreement between experimental response times and simulated response times. In order to investigate the vibration when the actuator is opened and closed, vibration experiments of the actuator are also performed. The results show that the measured vertical and horizontal accelerations are near the calculated acceleration of the plunger. Both of the experiments show that the optimization procedure is sufficiently accurate, and the optimal submersible electromagnetic actuator is sufficiently secure to be used in subsea BOP stacks.

A prototype of subsea solenoid valve for subsea blowout preventers is designed and manufactured. The deterministic and probabilistic thermal and electromagnetic finite element analyses are performed by using ANSYS software. The effects of uncertainties of five material properties, four physical dimensions and an applied voltage on the maximum temperature within the valve and the electromagnetic force with a given air gap are researched by means of Monte Carlo simulation (MCS) and response surface method (RSM). The thermal and electromagnetic experiments were done to validate the finite element analysis results. The results show that the radius of magnetic ring, applied voltage and thermal conductivity of 440C stainless steel have significant effects on the maximum temperature of subsea solenoid valve. The radius of plunger and inside radius of plunger sleeve have significant effects on the electromagnetic force of subsea solenoid valve. The results of finite element analysis and thermal and electromagnetic experiments indicate good matches. Therefore, the probabilistic finite element analysis shows its advantages in improving the development process and performance of subsea solenoid valves.
