2.7.4 Seismic Calculations
Table 2-2 Calculation of Overturning Force, X-direction
Symbol Unit Value Notes
Wp lb 961 Total Wt. of Axiom X-1000
h mm 850 Height of CG
L1 mm 800 Width of Machine
L2 mm 362 Distance from front, RHS of machine to CG in X
Symbol Value Equation Notes
R (lb) -590.2 Ra=Wp*(.85*L2-.94*h)/L1
For overturning force, 85% of Wp can be used to
resist overturning. This analysis is considering
Fp HPM = .94Wp.
Result: Tension Reaction at Feet, Machine
Requires Anchors.

h mm 850 Height of CG
L1 mm 965 Width of Machine
L2 mm 453 Distance from front, RHS of machine to CG in X
Symbol Value Equation Notes
R (lb) -412.2 Ra=Wp*(.85*L2-.94*h)/L1
For overturning force, 85% of Wp can be used to
resist overturning. This analysis is considering
Fp HPM = .94Wp.
Result: Tension Reaction at Feet, Machine
Requires Anchors.
 NOTE(s) This machine is in compliance with the SEMI 02-0200 standard when the feet are
anchored to the floor.
