Performance Evaluation and Optimization of Tie rod in Suspension System of Car for a Buckling study using Theoretical and Experimental approach

A tie rod is a slender structural rod that is used as a tie and capable of carrying tensile and compressive loads. As the ratio of its length to the radius of gyration of its cross section is normally quite large, it would likely buckle under the action of compressive forces. When it becomes worn out, steering will producing clunking noise and also the vehicle will typically be pulling or (dragging) to either side (left or right) it will cause the accident which is not safe for passenger life in the car. Thus the aim of the project is to analyze tie rod for active to improve the mass and buckling load of tie rod. This paper is aimed to assess buckling strength and compare buckling performance of Tie rod for different dimensions. Theoretically calculate the critical buckling load of Tie rod for taking different diameter of it and keeping the same material and length. Experimentally test the same Tie rod on UTM machine. Based on the experimental test results, theoretical calculation results the critical buckling load for different dimensions of tie rod were compared and it validated by checking its performance on quarter car test rig for suspension system of car.
