Finite element analysis 1
1) The document describes a finite element analysis project to design and simulate a cotter joint connecting two steel rods. 2) The objectives of the project are to learn modeling, design optimization, finite element analysis, and CAD/CAE software skills. 3) A cotter joint connecting two 30mm diameter rods and experiencing a maximum axial load of 50kN is designed, modeled, meshed, and simulated under static, modal, and transient loads. 4) The results of the simulations show the induced stresses are less than permissible stresses, indicating the joint will perform safely under actual operating conditions if manufactured as designed.

Project It isrequired to design a cotter joint which is used to connect two steel rods having same diameter.The maximum axial load on the joint is 50 kN.The material used for joint is 35C8 for Spigot and Socket and Cotter is made up of Mild Steel. Using factor of safety 5. Design all dimensions of the joint.Take ultimate shear stress half that of ultimate tensile stress and Ultimate Crushing stress double that of ultimate tensile stress.

Conclusion : Asthe induced stresses occurred on the assembly are lesser in magnitude than the permissible stresses when a tensile or compressive load of 50 KN is applied on it, it is evident through the simulation that the joint will perform safely when subjected to actual conditions if it is manufactured according to the design mentioned above.

Editor's Notes
- #7 The project work provides a general idea and information about finite element analysis. The Application of finite element analysis is very broad but for this project, only the engineering part will be emphasized. The engineering part consist of simulation of a particular object applied with different kinds of forces that induce stresses in it. It gives an idea of how the object will perform practically in actual world before manufacturing it. The project provides a description of different methods and procedures that are used to perform finite element analysis and the difficulties faced while performing it.
