The paper presents a modern method of constructive optimization of a plunger actuator with axial symmetry based on the electromagnetic simulation of several variants of magnetic circuit and excitation currents. On the basis of the force calculation developed by this actuator and the magnetic induction values in the core, we calculated the kinematic actuator parameters. Experimental determinations confirmed the precision and utility of the optimization method by electromagnetic simulation of the actuator.
The paper presents a method for verifying the thermal stability of an actuator with axial symmetry as a final stage of its assisted design. Thermal simulation of electromagnetically and cinematically optimized actuator is done by the Finite Element Method in Comsol Multiphysics (Heat Transfer Module). The thermal simulation is based on the geometry drawn in the Catia V5 and the material characteristics. Thermal simulation reduces the time and cost of designing actuators and prototypes.
