Week 1 Spur Gear Challenge

Report week 2

Aim: Using Cast Iron(ductile), Cast Steel and Cast Bronze as a material, carry out a static structural analysis to find out Equivalent stress, Total deformation and Stress intensity. Find location for possible fracture.

Procedure:

1. Find material

cast Iron

2. Import Geometry

Update model, open model

Create contact surface, 26 surfaces on each gear

Create joints, body-ground, revolte joint

Conclusion:

Static structral analysis was carried out on spur gear for the following material: cast iron, case bronze and cast steel. Based on strengh of material from results of equivalent stress and total deformation, case 2 cast bronze is the preferred material. Based on fracture machanics from result of stress intensity, case 3 cast steel is the preferred choice. The recomended choice of material is cast iron.
