Introduction to New Product Development
(Analysis)

2. Analysis:
Analysis means determining/describing the nature of the design by separating it into its parts to determine the fit between the proposed design and the original design goals

3. Analysis Answers These Questions
Will the product break?
Will it deform?
Will it get too hot?
Will it work?
Will it fail?

4. Analysis Can be performed manually Can be performed on computer
Computer increases analysis capability
Reduces its time

5. Manual Analysis Involves constructing a prototype and testing it
Very expensive
Very time consuming

6. Computer-Based Analysis
Two categories of computer-based analysis are:
Mass properties and
Finite or FEA (finite element analysis)

7. Mass Properties Analysis
Physical attributes of a mechanical part that relate to how the component will behave in an environment.
They include familiar attributes such as the
Weight or mass of the object
Volume of the object
Surface area
Center of mass
Moments of inertia
Bounding box

8. Finite Element Analysis (FEA)
Simulates physical behavior of a product design.
The process consists of subdividing all systems into individual components or "elements" whose behavior is easily understood.
And then reconstructing the original system from these components.
