Our objective is to make machinery for stamping details on water bottle cap. As company is small scale company it requires a machine with low cost, high accuracy, less floor area and less interaction of human being. We made a machine with same requirement using Geneva mechanism for indexing purpose which reduces human interaction. For stamping we use electromagnetic actuator which is actuated using ultrasonic sensors to read the location of cap under the plunger. Geneva table reduces the floor area and also makes the loading, unloading and indexing simple in one mechanism. Using sensors stamping becomes automatic and overall cost becomes very low as compared to the machineries used in industries like laser printing and all.

A linear electromagnetic plunger device generates linear force in the direction of the motion of the plunger. One of the essential components of the system is the core. The core is winded by conductor wires and the wires are energized by a power source. In this way the core windings produce magnetic flux by the help of the currents carried through the conductor wires. The generated magnetic flux navigates through the core component to the pertinent direction. By this way the directed magnetic flux generates motion on the plunger. This mechanism has wide application fields in automotive industry and machinery especially for areas commonly requiring a controlled actuator motion. There is limited range of opportunities to illustrate physical phenomena related to electromagnetics. Particularly in electromagnetics, it is so useful to use computational methods for illustrating phenomena about electromechanical conversion calculations of force in a magnetic circuit. For this purpose, it is practical to make use of a software such as EMWorks. Via EMWorks software, force in a magnetic circuit and current density distribution can be calculated and the results of numerical results can be presented in an automated manner. The mechanism of the plunger system involves electric energy conversion into magnetic force energy. The overall workflow is nothing but an electromagnetic energy conversion. One of the essential advantages of an electromagnetic plunger is that it can easily be controlled by an electric control and the response time of the plunger system is quite applicable for industrial applications. In this study, the main goal is to obtain magnetic flux density distribution yielding a generated force. Using the force generation calculation, the decision of the magnitude of current required can be obtained. Which amount of elecrtic current will result in how much force generation on the plunger, is the aim of this study. The EMWorks simulation software is used in this study to perform the electromagnetic simulations., Doğrusal bir elektromanyetik itici cihazı, pistonun hareket yönünde doğrusal bir kuvvet üretir. Sistemin temel bileşenlerinden biri nüvedir. Nüve, iletken tellerle sarılır ve tellere bir güç kaynağı tarafından enerji verilir. Bu şekilde nüvedeki sargılar, iletken teller aracılığıyla taşınan akımlar yardımıyla manyetik akı üretir. Üretilen manyetik akı, nüve bileşeni boyunca ilgili yöne doğru ilerler. Bu şekilde yönlendirilmiş manyetik akı, piston üzerinde hareket üretir. Bu mekanizma, otomotiv endüstrisinde ve özellikle kontrollü bir tahrik hareketi gerektiren alanlar için makinelerde geniş uygulama alanlarına sahiptir. Elektromanyetik ile ilgili fiziksel olayları açıklamak için sınırlı sayıda fırsat vardır. Özellikle elektromanyetikte, manyetik bir devrede elektromekanik dönüşüm hesaplamaları hakkındaki olguyu açıklamak için hesaplama yöntemlerini kullanmak çok faydalıdır. Bu amaçla EMWorks gibi yazılımlardan yararlanmak pratiktir.

This paper describes a scheme which allows two separate finite element meshes to slide into and thus overlap each other. The Lagrange multipliers method is used to couple the two meshes together at their boundary. Overlapping elements are dealt with by adjusting the contributions of the elements of one of the two meshes to the system matrix according to the extent of overlap in such a way that at total overlap, those elements are effectively decoupled from the model. Applications include the modelling of electromagnetic plunger type devices.

In this PhD, a design support methodology and framework is proposed. It aims at supporting designer tools and methods during the overall design process, by considering the complexity of product to design as well as the unpredictability of such a process. Our framework methodology is based on software component, which enables to integrate existing simulation software without programming in order to use it in services like optimization, for instance. A visual and recursive composition software allows to compose models in the framework, as well as to define and implement design process workflow. Some of the framework applications are detailed here like three-phased voltage transformer modelling and sizing, magnetic micro-actuator design or assistance during the concurrent design of an electromagnetic plunger., Ce travail de thèse propose une méthodologie et des outils pour un environnement d'aide à la conception. L'objectif est le support des outils et méthodes du concepteur durant le processus de conception en considérant la complexité des produits à concevoir et l'imprévisibilité de ce processus. Nous utilisons pour cela le concept de composant logiciels métiers à partir duquel il est possible, par exemple, d'intégrer des logiciels de simulation existants sans programmation, puis de les utiliser dans des services tels que l'optimisation. L'environnement dispose également d'un service de composition visuelle et récursive pour agréger les modèles, ainsi que pour définir et mettre en oeuvre le séquencement du processus de conception. Nous détaillons des applications de l'environnement pour dimensionner un transformateur de tensions triphasées, concevoir un micro-actionneur magnétique ou assister la conception collaborative d'un contacteur électromécanique.
