load test of steel frame for a 3D CNC mill
http://jwstolk.xs4all.nl/mill.htm
frame length : 2.21 m
frame material : 50x50x50x4mm steel U-beams
test load : 4x25 Kg
resulting frame flex: 0.05 mm
software : MegaPov 1.2.1
mechsim settings:
#declare E_steel = 200*1e9; // N/m^2 or pa
#declare A_U50x50x4 = ((50*50)-(42*46))*1e-6; // m^2
// choose a material and beam type:
#declare E_beam = E_steel; // N/m^2 or pa
#declare A_beam = A_U50x50x4; // m^2
// calculate stiffnes from elasticity and area:
#declare stiffness_beam = E_beam*A_beam; // N/m
time_step 1/50000000
jaap.
