You have been asked to design a small engine for a lawn mower. You will need to investigate the typical lawn mower engine size in the market and develop a competing design. You will need in your deign to look at how your mechanism will be balanced, the forces at each joint as well as the shaking / vibration forces that are inherent in your design. You will have complete control over bore, stroke, con-rod and crank lengths. Keep your design to a four stroke engine as shown below; you do not need to worry about the inlet/outlet part of the engine. A good starting point for reference is of "Design of Machinery" by Norton
Assessment:
- Calculations of the entire 360 degree stroke of your engine including, joint forces, shaking forces, and all calculations you used to balance your design and associated justifications.
- There should be a combination of spread sheet as well as simulation based results from SolidWorks motion.
- This is an individual assignment, all assumptions and boundary conditions must be listed.
