Otimização de material e geometria em magnetos de válvulas solenóides utilizando ambiente de simulação

Geometry and material optimization in solenoid valves magnets using simulation ambient

Souza, Derryck Antoniuk de; Marchese, Thais Barcella; , ;

Artigo:

Many diesel engines use electro valves in the fuel system in order to control the injection. Earlier models of these systems have pumps controlled by solenoid valves, in this case with a magnet with E shaped lamination and armature connected to the valve. It was used the theory of transformers and the core was determined with a lamination of stacked steel sheets. In the later diesel systems, the concept of the valve was changed, also the core material. Considering that, it was defined a study for the replacement of the core material, considering the development of the new materials and process available in the market. Since the component have a construction complexity, it was decided to perform a pre-analysis using a simulation ambient (ANSYS Maxwell and Siemens AMESim), in order to validate the material change and possible design optimization. The material choice was made considering the magnetic response to the PWM current generation and frequency, that impacts directly to the core losses. The main goal of this study is to determinate a material commercially available and that behaves on the same way as the current component, since no change in the performance is allowed. After the definition of material and geometry, samples were ordered for test bench validation.
