It is difficult to access and share design data among heterogeneous CAD systems. Usually different CAD systems exchange design data using a neutral format such as IGES or STEP. A prototype STEP database has been implemented. The prototype system uses the OpenCascade geometric kernel and the commercial object-oriented database ObjectStore. STEP provides the database schema. The STEP database has...

As the traditional mathematical modeling may lead to difficulties in solving a complex problem, a novel co-modeling and simulation method for the three-degrees-of-freedom (3-DOF) permanent-magnet spherical actuator (PMSA) is presented. After describing the basic structure and operating principle of PMSA, a geometry model is set up based on the SolidWorks. The dynamic characteristics are then an...

Indonesia adalah negara dengan komoditas pertanian yang melimpah. Salah satu banyak dimanfaatkan kentang. Olahan makanan berbahan kentang biasanya goreng berbentuk stik. Banyak dijumpai di pasar alat pemotong stik masih manual. sehingga untuk pekerjaan jangka panjang menjadi mudah lelah, membutuhkan tenaga cukup besar, dan beresiko lengan terkilir akibat beban berat. Perancangan mesin otomatis ...

AIM The aim of the present work was to study the size of cavity wall deformation in eight class I and II defects after composite restoration. MATERIALS AND METHODS 1. Creating a geometric model - data on the size of the left maxillary second premolar were obtained from a routine craniofacial scanning of a 20-year-old patient with a 2,5 Dental CT scanner (General Electric), with high resolutio...

Die-design for the die-casting process is a time consuming and complex activity that requires domain knowledge and vast experience of the die-designer besides information about manufacturing resources, part geometry, delivery time and cost preferences, etc. Complexity of the die-design activity further increases in case of a multi-cavity die. Currently available die-design systems lack in the l...

Background: A comprehensive database, comprising geometry and properties of human teeth, is needed for dentistry education and dental research. The aim of this study was to create a three-dimensional model of human teeth to improve the dental E-learning and dental research. Methods: In this study, a cross-section picture of the three-dimensional model of the teeth was used. CT-Scan images were ...

Obiectivul acestei lucrări este de a analiza prin Metoda Elementului Finit (FEM) şi de a optimiza dimensional radiatoarele frontale ale sistemului de răcire pentru transformatorul electric de putere TTU 630 kVA 20/0.4 kV din punct de vedere al transferului termic maxim. Analiza cu Elemente Finite a fost realizată cu ajutorul programelor software SolidWorks 3D CAD Design şi COSMOSFlow Works 2008...
