Week 8 Worm Gear Challenge
Week 8 Worm Gear Challenge
AIM
To carry out a transient structural analysis on Worm Gear with given material and give proper contact, joint, load are carry out in this analysis.
PROCEDURE
To find and compare the results of Equivalent stress, Total deformation, Equivalent strain on the worm gear challenge
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.
Import the geometry.
After import the model cut the gear by half so as to bring the model within limits.
After cutting the model
select the material.
strainless steel.
And open the model panel.
In connection panel use rename based on definition.
contact size = frictionless.
and select all faces
After that create joint.
connection type = body-ground.
rotational joint
Another joint.
connection type = body-ground.
rotational joint
mesh the component with mesh option
mesh the component with element sizing of 1.5mm.
Analysis the transient structural in analysis setting there are 15 steps
1st step
Auto time stepping : ON.
Large deflection : ON.
Weak spring : ON
Initial time : 0.2s
Minimum time : 0.2s
Maximum time : 0.5s
Output control : ON
step 2 to 15
Auto time stepping : ON.
Large deflection : ON.
Weak spring : ON
Initial time : 0.2s
Minimum time : 0.2s
Maximum time : 0.5s
Output control : ON
Use joint load on it.
Rotaional joint.
