Stress Analysis of the Front Suspension of a Formula Student Racing Car Using Solidworks Simulation Tools Abstract— the paper covers a simulation of the front suspension system which obtained a better way to analyze the problem. With the help of theoretical study‚ the simulation was conducted by using composite elements mesh for the system‚ which leads to a more accurate solution comparing to the single solid mesh model. Keywords—Suspension‚ Stress‚ Solidworks‚ Simulation‚ FEM. Introduction

are closely connected to the chemical community. Thomson used Crookes high vacuum cathode ray tube in his discovery of electrons. He found the green beam produced by the cathode ray tube was a completely negatively charged material. Experimenting with different electrically charged plates and magnets in the cathode ray tube and observing the deflection of the rays he had enough evidence to say that particles smaller than atoms existed. By doing this experiment multiple times he compiled enough data

tighten/untighten nuts or bolts‚ and cut through wires. Group 10 is to make a design for these pliers‚ make a 3D cad model on a design software package. The group is then to perform a series of analysis that include: load analysis‚ stress analysis‚ and deflection analysis. All is to be validated with a design software package. Background: The analysis of these pliers is going to depend heavily on the choice and use of materials. A basic understanding of material selection is in order. Most structural
