Workbench Simulation of a Magnetic Valve October 10, 2006 A Guide for Magnetic Simulation of a Magnetic Valve ANSYS Workbench Simulation Introduction The Magnetic Valve includes a fixed and a rotating part. The rotating body has to move, as quickly as possible, to rest in one of the 2 possible stop positions. Driving current patterns are the input to generate suitable torques. The customer experienced different performances of the valve for different current patterns: sometimes he got strong bumps on the mechanic stops and failures of the valve behaviour. the customer decided to commit a simulation of the magnetic and dynamic behaviour of the valve, instead to build a prototype. Analysis Goal The goal is ton achieve measure of the Magnetic Torque, as function of current and rotation angle within a parametric approach Owner: Enginsoft Usage Restrictions: Freely available for use Industry: Automotive Application: Valve Physics: Electromagnetics Product(s)/Version: ANSYS-v10.1 Geometry Type(s): Solid Geometry Format(s): Design Modeler Model Size: 147070 Nodes, 105742 Elements Element Type(s): Edge 117 Estimated Demo Time: 15 Minutes to show, 12 minutes running time Customer: Competition: Comsol, Ansoft Challenge: Free accurate Mesh, Parametric Model, Non Linear Magnetic Analysis Key Features Used: Sphere of influence for meshing, BH Non Linear Curve data import, Parametric Analysis Page 1 of 23
