Week 8 Worm Gear Challenge

Aim :

To analyse and solve the required solution of given Worm gear assembly using ANSYS software.

Objective :

To analyse the given model with the default material as structural steel and find the solution values.

Procedure :

Start from the workbench and choose Transient structural analysis.

From transient structural we add the material property in engineering data tab.

Import the given geometry to the geometry tab. We edit and go through the geometry using edit spaceclaim.

We set the model for analysis we move to mechanical module by using edit model.

We rename the geometry and assign the material property as default material (structural steel).

In connections we define the contacts between worm and gear tooth face in the given model.

We define joints like revolute body ground and revolute body ground.

We refine the mesh from the default value to get better solution values.

In analysis settings we do for 8 steps with weak springs as programme controlled, large deflection ON and auto time stepping ON.

We define the revolute joint for worm as rotational and we tabulate the values.

In solution tab we select the solution values which is required for the given model.

Equivalent stress :

Equivalent strain :

Total deformation :

conclusion :

The analysis of the given model is ran through and we got the required solution values and the values are,

Equivalent stress = 3054.8Mpa (max value over time), Eqivalent strain = 0.017986mm and Total deformation = 14.811mm.

Result :

The given worm gear assembly is analysed and got the solution values successfully using ANSYS software.
