Week 8 Worm Gear Challenge

Aim-

For this challenge, you will have to perform a transient structural analysis on a worm gear assembly. For the academic version, you need to cut the gear by half so as to bring the model within limits. For the challenge, you have to rotate the worm so as to get to almost end of the half cut and get results for Equivalent stress, Equivalent elastic strain and the total deformation in the model. You can use a finer mesh while performing the challenge and submit a well formatted report with appropriate images.

Procedure-

1) Open ansys workbench and drag transient strucutral into project shematics

2) now import the geometry and cut the gear onto half as specifeid in the requirments

3) Open model and rename the parts as below

now go to connection and rename the cnnections based on their definations

now reselect the contact faces for gear and chnage the type to fricitionless

now define 2 Body to ground revolute joints each for gear and worm

Now for mesh, give element size of 2mm to gear amd 1mm to worm

in analysis settings

steps- 15

initial step time-0.2

minimum step time-0.2

maximum step time-0.5

large deflection-on

weak springs-program controlled

in output control, turn everthinng to yes execpt, contact misclaneous

now add a joint load to revolute joint of worm gear

now in solutions add Equivalent stress, Equivalent elastic strain and the total deformation
