Comparison of the Materials for the Connecting Rod in ANSYS by using Fem Tool

Connecting rod is the intermediate link between the piston and the crank. And is responsible to transmit the push and pull from the piston pin to crank pin, thus converting the reciprocating motion of the piston to rotary motion of the crank. Connecting rod, automotive should be lighter and lighter, should consume less fuel and at the same time they should provide comfort and safety to a passenger that unfortunately leads to increase in weight of the vehicle. This tendency in vehicle construction led the invention and implementation of quite new materials which are light and meet design requirements. Lighter connecting rods help to decrease lead caused by forces of inertia in engine as it does not require big balancing weight on crankshaft. In this present work static structure analysis of the connecting rod is done and find out the best material for the connecting rod. Firstly a connecting rod model is creating in SOLIDWORKS software and then it imported in ANSYS software. After it boundary conditions applied on the connecting rod. We have selected three materials for connecting rod analysis (Aluminium Alloy 7068, Magnesium Alloy AZ91 and Titanium Alloy Ti6Al-4V). The automatic meshing of the connecting rod is done after meshing the nodes is creating 4295 and 2203 element of the connecting rod. The axial load applied is 28000 N (Compressive) on the small end of the connecting rod. The big end of the connecting rod is kept fixed. Out of three the minimum displacement and stress is produced in the Titanium Alloy Ti6Al-4V with value 0.00021514 mm and 2.5842e8 Pa.
