Week 2 Bevel Gear Challenge

Grid Dependancy Test and its uses:

• Grid dependancy test is nothing but by varying the mesh size and calculate the mesh value.
• For different mesh sizes , what are all the values we get is recorded in this test.
• The main purpose of this grid dependancy test is to record which mesh size will give the optimum result.

Grid Dependancy Test:

• For the given Bevel gear simulation the grid dependancy test has been performed, for mesh sizes of 6,5 and 4 mm.

• ANSYS WB,

  • At first we open static structural in ANSYS work bench.
  • Now start to give the material card as structural steel.
  • Give all the material Boundary conditions.
  • Now import the given bevel gear geometry model.
  • Next Give all the required aspects on the branch.
  • Give contact details, creat joints, analysis settings, Joint load etc...
  • Give initial time step as 0.2s, min. time step as 0.1, give max time step as 1 s.
  • Now in the solution part record the values of the stress, strain and deformation.

Presentation:

• The results of the grid dependancy is recorded and analysed.
• At first we usesd mesh size as 4 and then for the second time we use mesh size as 5 and third time we use mesh size as 6.
• After that we recorded the optimum value of the bevel gear model.
• Next the model is archived and saved after that it's uploaded.
