And more…

4. Physical Property Analysis
The size, volume, surface area, and other properties available from a solid model are most often part of the design constraints your design must satisfy.
The following are physical property calculations typically available in today’s solid modeling programs:
Volume Density Mass
Surface area Centroid Moment of Inertia
Product of Inertia Radii of Gyration Principal Axes
Principal Moments

5. Physical Property values can
To open the Physical Property information, right click the solid model name in the Browser.
Select iProperties
Physical Property values can
be used for predicting material quantity needed for production, finishing, packaging and shipping.

6. Finite Element Analysis
Select different test results from the Results folder in the Stress Analysis browser panel.

7. Failure Testing Crash Tests Dynamometer Drop test Flammability Product
Disassembly

8. Product Disassembly
Disassembly or teardown of a product is a major step in the reverse engineering process
It uncovers the principles behind how a product works
It is always fun to tear apart a product, but nothing will be accomplished if data is not collected during the process
To gather this data, we will use a Product Disassembly Chart

9. Answer the Following Questions
Presentation Name
Course Name
Unit # – Lesson #.# – Lesson Name
Answer the Following Questions
How do the parts interact?
What are the good and bad features of the product?
Form
Function
What has caused the product to succeed or fail?
Are the materials appropriate?
What manufacturing process was used?
What is the estimated cost of the product?

10. Why Disassemble a Product?
To identify components and interaction of components
To determine strength and weaknesses of parts
To understand the operation
To develop (computer) documentation

11. Initial Product Selection
A product is selected for RE
The product can range from simple (child’s toy) to complex (fishing reel)

12. Suggested Supplies for Disassembly
Small drill
Calipers
Screwdriver set
Socket set
Wrenches
Wire cutters
Needle nose and regular pliers
Radius gauge
Hand saw / miter box and back saw
Scale
Protractor
Handout – Product Teardown Chart
Hand tool to compress springs
DO NOT DESTRUCTIVELY DISASSEMBLE AND AUTOMOBLOX VEHICLE

13. Product Disassembly and Documentation Procedure
Disassemble the product
Create pictorial or multiview sketches to
Carefully observe and measure each part
Record your finding on the Product Disassembly Chart and your sketches
Create an annotated sketch of each part
Create 3D solid models for each part
Document your findings in the presentation
