INTODUCTION

Intoduction to CATIA V5R19

CATIA (Computer Aided Three-dimensional Interactive Application) is a multi-platform CAD/CAM/CAE commercial software suite developed by the French company Dassault Systemes and marketed worldwide by IBM. Written in the C++ programming language, CATIA is the cornerstone of the Dassault Systemes product lifecycle management software suite. Through its exceptionally easy –to- use state of the art user interface, CATIA delivers innovative technologies for maximum productivity and creativity, from concept to the final product. CATIA reduces yhe learning curve ,as it allows the flexibility of using feature-based and parametric designs.

CATIA provides three basic platforms: P1, P2, P3. P1 is for small and medium sized process oriented companies that wish to grow the large scale digitized product definition. P2 is for advanced design engineering companies that require product, process and resources modeling. P3 is for high end design application and it is basically for Automotive and Aerospace industry, where high quality surfacing or Class-A surfacing is used for designing.

History :

CATIA started as an in-house development in 1977 by French aircraft manufacturer Avions Marcel Dassault, at that time customer of the CADAM CAD software.

Initially named CATI (Conception Assistée Tridimensionnelle Interactive — French for Interactive Aided Three-dimensional Design ) — it was renamed CATIA in 1981, when Dassault created a subsidiary to develop and sell the software, and signed a non-exclusive distribution agreement with IBM.[2]

In 1984, the Boeing Company chose CATIA as its main 3D CAD tool, becoming its largest customer.

In 1988, CATIA version 3 was ported from mainframe computers to UNIX.

In 1990, General Dynamics Electric Boat Corp chose CATIA as its main 3D CAD tool, to design the U.S. Navy's Virginia class submarine.

In 1992, CADAM was purchased from IBM and the next year CATIA CADAM V4 was published. In 1996, it was ported from one to four Unix operating systems, including IBM AIX, Silicon Graphics IRIX, Sun Microsystems SunOS and Hewlett-Packard HP-UX.

In 1998, an entirely rewritten version of CATIA, CATIA V5 was released, with support for UNIX, Windows NT and Windows XP since 2001.

In 2008, Dassault announced and released CATIA V6. While the server can run on Microsoft Windows, Linux or AIX, client support for any operating system other than Microsoft Windows is dropped.

Industries using CATIA

CATIA is widely used throughout the engineering industry, especially in the automotive and aerospace sectors.

Aerospace

The Boeing Company used CATIA V3 to develop its 777 airliner, and is currently using CATIA V5 for the 787 series aircraft. They have employed the full range of Dassault Systemes' 3D PLM products — CATIA, DELMIA, and ENOVIA LCA — supplemented by Boeing developed applications.

Chinese Xian JH-7A is the first aircraft developed by CATIA V5, when the design was completed on September 26, 2000.

European aerospace giant Airbus has been using CATIA since 2001.

Canadian aircraft maker Bombardier Aerospace has done all of its aircraft design on CATIA.

The Brazilian aircraft company, EMBRAER, use Catia V4 and V5 to build all airplanes.

Vought Aircraft Industries use CATIA V4 and V5 to produce its parts.

The British Helicopter company, Westlands, use CATIA V4 and V5 to produce all their aircraft. Westlands is now part of an Italian company called Finmeccanica the joined company calls themselves AgustaWestland.

The main supplier of helicopters to the U.S Military forces, Sikorsky Aircraft Corp., uses CATIA as well.

Automotive

Many automotive companies use CATIA to varying degrees, including BMW, Porsche, Daimler AG, Chrysler, Audi,[11] Volkswagen, Bentley Motors Limited, Volvo, Fiat, Benteler AG, PSA Peugeot Citroën, Renault, Toyota, Ford, Scania, Hyundai, Škoda Auto, Tesla Motors, Proton, Tata motors and Mahindra & Mahindra Limited, [[MLR motors, Hyderabad][International cars & motors ltd(Sonalika group0,http://www.icml.co.in]. Goodyear uses it in making tires for automotive and aerospace and also uses a customized CATIA for its design and development. Many automotive companies use CATIA for car structures — door beams, IP supports, bumper beams, roof rails, side rails, body components — because CATIA is very good in surface creation and Computer representation of surfaces.

Shipbuilding

Dassault Systems has begun serving shipbuilders with CATIA V5 release 8, which includes special features useful to shipbuilders. GD Electric Boat used CATIA to design the latest fast attack submarine class for the United States Navy, the Virginia class . Northrop Grumman Newport News also used CATIA to design the Gerald R. Ford class of supercarriers for the US Navy.

Other

Architect Frank Gehry has used the software, through the C-Cubed Virtual Architecture company, now Virtual Build Team, to design his award-winning curvilinear buildings. His technology arm, Gehry Technologies, has been developing software based on CATIA V5 named Digital Project. Digital Project has been used to design buildings and has successfully completed a handful of projects.

Solid Modeling

'Solid Modeling' is a method used to design parts by combining various 'solid objects' into a single three-dimensional (3D) part design. Originally, solid modelers were based on solid objects

being formed by primitive shapes such as a cone, torus, cylinder, sphere, and so on. This evolved into solid objects being created and formed from swept, lofted, rotated, and extruded 2D wireframe or sketch geometry.

Because of their limited use, some solid modelers have abandoned the primitive shapes altogether in favor of predefined library solid objects. 'Stock' library objects provide the designer with a similar shape to begin the design with, eliminating some of the initial tedious design work.

The real power of a solid modeling application is how it can take the solid objects and combine them together by intersecting, joining, or subtracting the objects from one another to create the desired resulting shapes. Because everything in a solid model design is a 'watertight' model of the part, the solid modeler is able to know the topology of the entire model. By topology we mean that it knows what faces are adjacent to each other and which edges are tangent.

 

Since the solid

modeler's database knows so much about the entire part model, it can perform functions virtually impossible with surface modeling. For example you can fillet all the adjacent edges of a face to other faces in a single command. Another popular example is the 'shell' function of solid modelers. This allows you to define a constant wall thickness for the entire model with a simple task with a single command

constraints in solid modeling

Most solid modelers support 'geometric constraints'. A geometric constraint is the relationship of an entity to other entities. Constraints are only used on the underlying sketch or wireframe entities that define the solid object bounaries. Some common 'constraints' for these entities are coincident, collinear, intersect, parallel, perpendicular, and tangent. When one or more entities are 'constrained' to each other, changing any of the entities will most likely have an effect on the others. In the example , the lines and arcs have been assigned tangent constraints to each other and two arc are mirror to each other . When one of the arcs in the solid's boundary sketch is changed other one is also changed.

Some solid

modelers automatically assign the constraints for you as you design the part. Others provide the ability to assign constraints as you are designing. CATIA will automatically assign constraints where it thinks you want them and then allow you to modify or remove them manually later.

In following example tangent constraint is automatically assign by CATIA

Single entity attributes such as 'horizontal' and vertical' are also considered to be constraints, since tagging an entity with one of these attributes will keep the solid modeler from changing it when other entities that have relationships to it are changed.

Constraints are one of the system basics needed to provide true geometric associativity. Most solid modelers will allow you to add and modify constraints as needed. There are even some solid modelers that will attempt to automatically assign the required geometric constraints logically from the steps you take to design the part

Solid modeling vs. Surface modeling:

For designs that require any combination of fillets along multiple edges, contain drafted surfaces, or constant wall thickness, solid modeling is far superior to surface modeling.

For designs that require sculptured surfaces with a lot of curvature (the mouse you are using on you computer comes to mind) a surface modeler is far easier than a solid modeler. In fact it may be virtually impossible to create some shapes with a solid modeler and hold exact dimensions for very complex shapes.

BUTTERFLY VALVE ASSEMBLY:

A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required.

A butterfly valve is from a family of valves called quarter-turn valves. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.

Structure

Butterfly valves are valves with a circular body and a rotary motion disk closure member which is pivotally supported by its stem. A butterfly valve can appear in various styles, including eccentric and high-performance valves. These are normally a type of valve that uses a flat plate to control the flow of water. As well as this, butterfly valves are used on firefighting apparatus and typically are used on larger lines, such as front and rear suction ports and tank to pump lines. A butterfly valve is also a type of flow control device, used to make a fluid start or stop flowing through a section of pipe. The valve is similar in operation to a ball valve. Rotating the handle turns the plate either parallel or perpendicular to the flow of water, shutting off the flow.
