Introduction to CAD

Use of computer systems to assist in creation, modification, analysis and optimization of a design.

Computer assistance, while a designer converts his or her ideas and knowledge, into a mathematical and graphical model represented in a computer.

software is used to create and design models.

Fundamentals of CADModern CAD systems are based on Interactive Computer Graphics (ICG).

ICG is a system in which computer is used to create, transform, and display data in the form of pictures or symbols.

The ICG system and the human designer are the major components of a CAD system. Interactive computer graphics is a tool used by the designer to solve a design problem. In effect, the ICG system magnifies the powers of the designer. This has been referred to as the synergistic effect.

The designer performs the portion of the design process that is most suitable to human intellectual skills (conceptualization, independent thinking) whereas the computer performs the task best suited to its capabilities (speed of calculations, visual display, storage of data), and the resulting system exceeds the sum of its components.

Fundamental reasonsfor implementing a CAD system

1. To increase the productivity of the designer.

2. To improve the quality of the design.

3. To improve communication.

4. To create a database for manufacturing.

Introduction to CAE

Computer-Aided Engineering is the use of computer software to solve engineering problems with the improvement of graphics displays, engineering workstations, and graphics standards.

Engineers also use computer programs to estimate the performance and cost of design prototypes and to calculate the optimal values for design parameters. When combined with CAD, these automated analysis and optimization capabilities are called computer-aided engineering (CAE)

Page 13: Abhijeet Pombarekar

Goals of CAE

The goals of computer-aided engineering (CAE) include:

Improved product quality and safety

Reduced engineering time, achieved through fewer design iterationsImproved product functionality and usability

Reduced number of prototypes, ultimately leading to their elimination in many cases

Reduced product cost

Scenarios and Applications of CAEMechanical Engineering1. Finite Element Analysis (FEA):

●Structural analysis of a component’s behaviour under various kinds of applied loads and supports e.g. Beam and Grid structures.

●Thermal analysis of a structure’s behaviour when it is subjected to heating and cooling.

●Combined structural and thermal analysis.

Mechanical Engineering

2. Mechanism Analysis:

Mechanism analysis studies the behaviour of mechanical systems undergoing motion. Typically, the geometry, mass, inertia, compliance, stiffness, and damping of the system’s components as well as the forces and loads applied from outside the system must be defined. Equations of motion are developed and solved. The results of the analysis may include positions, velocities, accelerations, forces (applied, reactive, and inertial), determination of equilibrium positions, and other computed parameters.
