COMPUTER AIDED ENGINEERING
Computer aided engineering (CAE) is an analysis performed at the computer terminal using a CAD system. It includes computer-aided design (CAD), computer-aided analysis (CAA), computer-integrated manufacturing (CIM), computer-aided manufacturing (CAM), material requirements planning (MRP), and computer-aided planning (CAP). Its purpose is mainly to analyze the different materials, products, their performance and quality, such as durability, stability, etc. It has many advantages like improved safety and product quality, reduced product cost, customer satisfaction, etc. and so it has many applications like used to analyze the properties of material, commercial and flight simulations, etc. It has 3 phases: pre-processing, analysis solver, post- processing of results.
CAE is mainly of 3 types: finite element analysis (FEA), computational fluid dynamics (CFD), and Boundary Element Analysis (BEA). FEA is used to conduct static and dynamic analysis. CFD is used to optimize components for efficient fluid flow and heat transfer. BEA is used to predict noise characteristics on various systems.
One of the real world examples is MEMS that is micro electro mechanical systems. It has the size of a grain of salt or the eye of a needle.
DEFINITON OF CAE:
Computer aided engineering (CAE) is an analysis performed at the computer terminal using a CAD system. It includes computer-aided design (CAD), computer-aided analysis (CAA), computer-integrated manufacturing (CIM), computer-aided manufacturing (CAM), material requirements planning (MRP), and computer-aided planning (CAP). CAE mainly depends on CAD. It is usually used in every industry such as aerospace, automobile industry.
GOALS OF COMPUTER AIDED ENGINEERING
The goals of computer-aided engineering (CAE) are:
• improved product quality
• improved safety
• reduced engineering time, achieved through fewer design iterations
• improved product functionality and usability
• reduced number of prototypes, ultimately leading to their elimination in many cases
• reduced product cost.
These goals has helped computer aided engineering to achieve various heights like:
- CAE can be used to perform variety tests like car crash the test simulation.
- Can be used for Commercial and military flight simulations.
- It is also used to analyze properties of different types material used in production application of computerized methods during the design of technical systems.
- It increases production efficiency and quality through better designs.
- It is also a Tool for decision making-what the product is going to look like, its performance characteristics, what improvements need to be made?
- CAD analysis on be done on the computer screen.
- There is no need to build products’ prototypes.
- Results of analysis is essential and can be saved for future of the product.
- Customer satisfaction is priority and can be achieved through CAE.
- CAE has to be compliant with many U.S. and international standards and so the product real-world performance and safety is achieved.
PHASES OF CAE / CAE
applications support a wide range of engineering disciplines or phenomena including:
- Stress and dynamics analysis on components and assemblies using finite element analysis (FEA)
- Thermal and fluid analysis using computational fluid dynamics (CFD)
- Kinematics and dynamic analysis of mechanisms (multi body dynamics)
In general, there are three phases in any computer-aided engineering task:
- Pre-processing – defining the model and environmental factors to be applied to it. It is typically a finite element model, but facet, voxel and thin sheet methods are also used in this phase.
- Analysis solver- it is usually performed on high powered computers.
- Post-processing of results – it is the last phase in any computer aided engineering task and is done using visualization tools.
This cycle is iterated, often many times, either manually or with the use of commercial optimization software.
BENEFITS OF CAE
The benefits of CAE are:
- Reduced product development cost and time, with improved product quality and durability.
- Designs can be evaluated and refined using computer simulations
- CAE helps engineering teams manage risk and understand the performance implications of their designs
APPLICATION OF CAE
- In area of piping plant design in civil engineering.
- In roadway design, most surveying function.
- Used in many specialized analysis, for circuit design, VLSI device design, and simulation.
- Used in Mechanical event simulation (MES).
- Control systems analysis.
- Simulation of manufacturing processes like casting, molding and die press forming.
- Optimization of the product or process.
