AIM: To perform the simulation of Lifting Lug.

LIFTING LUG:

A Lifting lug is a plate with a hole in it. As the term specifies, lifting lugs are used for lifting. The hole is sized to fit a clevis pin. Using lifting lugs combined with the clevis pins, loads are transferred from one mechanical component to another. For mechanical static equipment (Fig. 1), these lifting lugs are used by cranes for transportation and installation.

While lifting the mechanical equipment, the lugs must be able to carry the complete weight of the equipment. Also, while transporting and installation various kinds of forces act on those lifting lugs. Hence, the lifting lug design has to be accurate enough to avoid any failure. In this article, we will briefly explore the lifting lug .

Here in this Project we are going to analyse the stress analysis on the Lifting lug under certain load conditions.

DRAWING

PROCEDURE:

.open ansys ,click on static structural ,drag and drop it into project schematic.
.open meterial data and select structural steel.
.open spaceclaim,import the geometry and update it.
.then open mechanical module ,and change the contacts settings.
frictional contact between base and lifting lug.
bolts to base and bolts to lifitng lug bonded.
frictionless between bolts to lifting lug.
.Then do the meshing ,multizone method to full model and then face sizing on the main faces in contact(1.5mm)
.put certain boundary conditions
Fixed support to the base bottom side.
Bearing loads of 7000N in z-dirn and 1000N in Y- dirn.
Bolt pretension of 2000N to all the four bolts
.Then solve the model and evaluate Equivalent stress,Equivalent elastic strain ,FOS etc.
