Static Structural Analysis of Buckle-Clip with different cases using ANSYS WORKBENCH

Objective: Perform Static Structural Analysis of Buckle-Clip with two different conditions and compare the results.

Pre-processing Setup:

Geometry:

Materials:

POM materials is created by editing structural steel

Contacts:

Mesh:

Analysis Settings:

Case 1:

Moving Buckle and Clip is fixed:

Fixed support provided for Clip

Displacement given to Buckle

Solutions:

Total deformation:

Min. value = 0 mm , Max, value = 50 mm

Equivalent stress generated by clip:

Min. value = 4.29e-8 MPa , Max. value = 45.63 MPa

Contact Pressure :

Min. value = 0 , Max. value = 11.94 MPa

Case 2:

Moving Clip and Buckle is fixed:

Fixed support provided for Buckle

Displacement given to Clip

Solutions:

Total deformation:

Min. value = 0 mm , Max, value = 49.876 mm

Equivalent stress generated by clip:

Min. value = 5.17e-7 MPa , Max. value = 63.90 MPa

Contact Pressure :

Min. value = 0 , Max. value = 11.927 MPa

Comparing cases of different results in Tabular data:

Cases	Total deformation in mm		Equivalent stress in MPa		Pressure in MPa
	Min	Max	Min	Max
Clip moving Buckle fixed	0	49.876	5.17e-7	63.904	0.1192
Buckle moving Clip fixed	0	50	4.29e-8	45.63	0.1194

Interface:

In case 1(Buckle moving clip fixed) , When buckle just comes in contact with clip , there is an deformation in shape of clip which is observed as a result pressure starts increase gradually. As soon as buckle reaches top faces of clip , the pressure obtained is maximum and then it starts to come down and move in a constant way until buckle enters clip fully on which it becomes zero and the shape of clip comes to original position.

In case 2(Clip moving Buckle fixed), When clip comes in contact there is an deformation observe in clip with buckle coming in contact with it. The pressure starts to increase when top faces of clip touches the buckle , Pressure remains constant . After that when clip starts to come on its original deformation , Pressure increases rapidily and then falls as clip comes to its original shape becoming zero.

Comparing both cases, More deformation is used when clip is moving buckle fixed. More stress is obtained in case 1. Contact Pressure is maximum in Buckle moving when clip is fixed.
