EM Modeling of Aircraft Fuel Systems

EM Modeling of Aircraft Fuel Systems
EADS, Innovation Works in the UK uses CST EM STUDIO® to aid in the simulation of aircraft fuel systems. EADS has developed an internal code for modelling the filling of an aircraft fuel tank. The code simulates this scenario and outputs the electric field, charge density and potential at various points in the tank and fuel over the filling period. Read full article..

3D Magnetostatic Analysis of Magneto-Inductive Devices for NDT

3D Magnetostatic Analysis of Magneto-Inductive Devices for NDT Document type
This work presents the 3D magnetostatic numerical analysis based on Finite Integration Technique applied to the design of magneto-inductive devices for the Non Destructive Testing (NDT) of ferromagnetic ropes. The problem is characterised by several design aspects and by the high saturation level reached in the device core and in the rope under testing. CST EM STUDIO® was used for the virtual prototyping which entailed the the optimisation of permanent dimensions using 3D non-linear magnetostatic optimisation. Measured versus simulated results are presented. Read full article..

VBA Macro for the construction of an EM 3D model of a tire and part of the vehicle.

VBA Macro for the construction of an EM 3D model of a tire and part of the vehicle. Document type
Guillermo Vietti, Politecnico di Torino A VBA script has been developed, controlling all CST STUDIO SUITE™ tools to represent all mechanical elements in the space around the tire in a vehicle, incorporating this complex geometry in a parametric way. One of the applications of this script is for the study of EM field propagation inside and outside the tire. The same script is capable of choosing the appropriate mesh parameters to optimize the simulation time, with the radiating element inside the tire. It is capable also to set field monitors at all frequencies and to run the simulation automatically. The tire geometry is mainly designed with azimuthally variable tire sections, taking in account the deformation of the tire. The main advantages of designing a parametric geometry controlled by a VBA script are the possibility of: -> adapting the model to different vehicles and tires. -> studying the EM propagation in the whole 3D space for different orientations of the tire and angular positions of the radiating element, without the need of re-designing the structure. -> changing the deformation of the tire near the ground surface due to the load of the vehicle, taking into account the asymmetries of the model. The EM effect of this deformation on the propagation depends on the position of antenna. -> running many iterative simulations, changing iteration variables simply introducing the VBA script inside a cycle “for … next”.

Magnetostatic simulation of a magnetic injection valve

Magnetostatic simulation of a magnetic injection valve
CST EM STUDIO™ (CST EMS) is applied to the simulation of a magnetic injection valve by use of its non-linear magnetostatic solver. The aim of the simulation is to obtain the force on the valve armature as a function of the air gap between the armature and the main valve housing. Using the powerful and easy-to-use parameterisation features in CST EMS, a familly of force curves as functions of gap and excitation current can be easily generated. Read full article..
