Friends and Solid Works Experts,

 

I have been trying to solve this problem since couple of days and i need some direction from you guys.

 

This is the bracket on which i am running a linear static study:

Given below is the schematic of assembly where this bracket is used:

Basically this bracket holds a part through 4 vacumm cups ( on one side) , the total mass of the part is 80 Kg and accelration forces are 270N acting horizontal through each of these 8 vacumm cups. ( I assumed that total mass is equally supported by all 8 cups hence 80/8=10Kg (100N) force acting through each cup)

 

 

I basically want to find out if the stress due to these forces are not causing the bracket weld to fail. ( Cause some of these brackets failed at our customer site)
