Mechanical Design
Introductory book
A very good introductory book about Mechanical Design is:
- [Skakoon2008]Skakoon J.G., The Elements of Mechanical Design, ASME Press, 2008.
Main rules from this book:
Create designs that are explicitly simple - keep complexity intrinsic
Keep the functions of a design independent from one another
Use exact constraint when designing structures and mechanisms. Never overconstrain a design!
- Plan the load path in parts, structures and assemblies.
Triangulate parts and structures to make them stiffer
- Avoid bending stresses. Prefer tension and compression.
Improve designs with self-help.
Manage friction in mechanisms. Use friction deliberately or avoid it completely.
Important topics:
Important topics in Design and Mechanical Design in particular are:
