Week 1 Spur Gear Challenge

Introduction

In this challenge i have performed Static structure analysis on spur gear model in order to find equivalent stress, total displacement and stress intensity. I have used three diffrent materials namely cast iron, cast steel and cast bronze in static structure analysis to evalute the ideal material for spur gear model.

Case 1

In case 1 i have considered cast iron as a material and carried out static structural analysis and the results of analysis are tabulated below.

	Max Displacement (mm)	Max Stress (Mpa)	Max Stress Intensity (Mpa)
Case 1	4.77	52.09	57.429

Case 2

In case 2 i have considered cast steel as a material and carried out static structural analysis and the results of analysis are tabulated below.

	Max Displacement (mm)	Max Stress (Mpa)	Max Stress Intensity (Mpa)
Case 1	4.77	38.196	42.71

Case 3

In case 3 i have considered cast bronze as a material and carried out static structural analysis and the results of analysis are tabulated below.

	Max Displacement(mm)	Max Stress (Mpa)	Max Stress Intensity (Mpa)
Case 1	4.77	96.163	106.52

Comparision of results for three cases

	Max Displacement(mm)	Max Stress (Mpa)	Max Stress Intensity (Mpa)
Case 1	4.77	52.09	57.429
Case 2	4.77	38.196	42.71
Case 3	4.77	96.163	106.52

Animation of displacement, stress and stress intensity are attached below.

Conclusion

I can recommend cast steel as a material for spur gear after seeing the analysis results we can observe that cast steel parameters are less compare to cast iron and cast bronze.
