Week 1 Spur Gear Challenge
Aim- To carry out the static-structural analysis on the pair of spur gear with 3 different materials. And to conclude which material is best for the spur gear based on the results.
Common Specifications of the Analysis:-
1) Meshing Element Size - 0.001m
2) No. of Nodes - 17860
3) Elements - 3088
4) Type of Joint - Revolute
5) Connection Type - Body to Ground
6) Right Gear - Rotating
7) Left Gear - Moment (10 N.m)
8) No. of Steps - 6 each of 30 degrees
