How to conduct FEA on this part?

Hi All,


I'm trying to run an FEA on this part to find the yeilding point of this part with a certain amount of weight it holds. The part is an around all welded bracket which pivots on its spindles in one plane. Please see the images to see how its mounted on the device. On the flat bit, it carries the weight of a mast and a few components on top which is bolted on by 4 bolts.


Where the small hole is next to the arm, that part gets pulled by an actuator. The part moves the mast from a horizontal resting position to a vertical position. I have worked out the moment for the mast with the weight on top but I'm unsure what fixtures and where I should apply the forces to get an accurate results of the stresses. The material of the main part is mild steel. I have attached the moments calculations in the zip file too.


The total weight of the mast is: 41kg


Any help will be much appreciated.


Kind Regards,
