Week 1 Spur Gear Challenge

OBJECTIVE:

To perform a spur gear simulation for 3 different materials of gear and analyze the results.

METHODOLOGY:

• First add the materials fromm the material library to the engineering data
• import the geometry and assaign the material to the geometry.
• 
• define the contact between the gear and give the joints to each gear.
• 
• 
• mesh the geometry and perform the face sizing on the tooth surface for good results.
• 
• perform the analysis in 6 steps and give the joint load and joint moment to the gears in the form of tabular data.
• 
• run the simulation and analyse the results for different materials.

CASE 1: cast iron

CASE 2:cast steel

CASE 3:bronze cast

material	equivalent stress(Mpa)	total deformation(mm)	stress intensity(Mpa)
cast iron(ductile)	647.16	30	512.14
cast steel	702.52	30	503.13
bronze cast	561.04	30	462.63

STRESS INTENSITY : it measures the stress concentration at a region where the crack is likely to form.

CONCLUSION:

from the above data we can conclude that bronze cast material shows better stress results and can withstand more load compared to the other two materials.
