Snap Fit analysis of a Plastic Buckle
Objective: To Simulate the Snap-Fit analysis For Plastic Buckle-Clip
Case1: Moving the clip by keeping the buckle fixed.
Case2: Moving the buckle by keeping the clip fixed
Geometry
Material
- POM is used For both Buckle and clip
Connection
Contact
- Frictional type of contact is created between the clip and buckle with frictional coefficient as 0.2
Mesh
Body sizing is given for the buckle components
Element size 5mm
Case1: Moving the clip by keeping the buckle fixed.
Analysis Setting
Boundary Conditions
- Fixed support is given to the Buckle
- Displacement is given to the Clip Along -z axis
Case 2 Moving the buckle by keeping the clip fixed
Analysis Setting
Due to Convergence Issues
- Auto Time Stepping is set On
- Minimum and Maximum Time Step is Defined
Boundary Condition
- Fixed support is given to the Clip
- Displacement is given to the buckle Along z axis
Post Processing
- Equivalent Stress For Clip
- Total Deformation for the Clip
- Contact Pressure
Solution Ouput
CASE 1
Equivalent Stress For Clip(4.3558Mpa)
Total Deformation for the Clip(49.806mm)
Contact Pressure(Max 15.481MPa)
CASE 2
Equivalent Stress For Clip(11.509Mpa)
Total Deformation for the Clip(2.3583mm)
- Since the Buckle is moving the clip is fixed 2.3583mm is Max Deformation along X axis
Contact Pressure(Max 34.546MPa)
Conclusion:
In this report We Performed Snap Fit Analysis For Buckle & Clip with Two cases without any Convergence issues
