Abstract
This paper focuses on deriving an optimal moving coil actuator design, used as force producing element in hydraulic on/off valves for Digital Displacement machines. Different
moving coil actuator geometry topologies (permanent magnet placement and magnetization direction) are optimized for actuating annular seat valves in a digital displacement
machine. The optimization objectives are to the minimize the actuator power, the valve flow losses and the height of the actuator. Evaluation of the objective function involves
static finite element simulation and simulation of an entire operation cycle using a single chamber Digital Displacement lumped parameter model. The optimization results shows that efficient operation is achievable using all of the proposed moving coil geometries, however some geometries require more space and actuator power. The most appealing of the optimized actuator designs requires approximately 20 W on average and may be realized in 20 mm Ø 22.5 mm (height diameter) for a 20 kW pressure chamber.
The optimization is carried out using the multi-objective Generalized Differential Evolution optimization algorithm GDE3 which successfully handles constrained multi-objective
non-smooth optimization problems.
