The document discusses the function and construction of a connecting rod, which converts the reciprocating motion of a piston into rotary motion for a crankshaft. It includes a pressure analysis simulation using ANSYS, revealing that under 20 MPa pressure the design remains safe despite some minor deformations. Various components of the connecting rod are outlined, with references provided for further reading.
Design and analysis of a connecting rod
- 1. Submitted by; • Amartya Roy(1602218) KIIT DU
- 2. Abstracts • A Connecting rod is used to transfer reciprocating motion of piston into rotary motion of crankshaft. This whole process is done by cylinder, piston, crankshaft and connecting rod. It has two ends - Small End and Big End. The small end is connected to piston with piston pin and the big end is hold by crankshaft through crankpin. The small end may have a solid or split eye but the big end is always split. The split shoulder end is assembled with a cap by clamping bolt.
- 3. Construction • It consist of following parts, 1. Shank 2. Lower and upper bearing 3. Bearing cap 4. Bolt 5. Nut
- 5. Design in
- 6. Pressure analysis in • Firstly we kept the lower hole as a fixed part then we apply 20Mpa pressure in the front end then simulate in ANSYS
- 8. Conclusion • Under 20 Mpa pressure the upper end of the connecting rod is getting slightly deformed and we can see red mark but the stress isn't exceeding the yield value , hence the design is safe.
