Hey guys, I have to do a simple simulation in solidworks but can´t make it work!
What i'm trying to do: a simple handrail with 150kgf/m load, lenght 1,5m and 1,2m height.
I need to simulate just the "top tube" under load.
The vertical tube goes inside a slightly bigger tube of 350mm tall, working as a hinge...
So, to simulate this fixture, I added a splitline 350mm tall and made the bottom section as a hinge.
But doing by hand I got huge deviation on stress.
The top part in Solidworks is rated at 200MPa and "by hand" I only have 92 MPa.
L = 1,5m
F = 150 kgf /m
L = 150 x 1,5m = 225kfg * 9,80 N = 2205 N
Bend = 2205N * (150*0,5)cm = 165375 N*cm
Tube is 3,175cm ext and 2,575cm int, so W would be:
W = pi * (D^4 - d^4)/32*d = 1,78 cm3
