Output File: ReStackor Calculation
The definitions of each output parameter are given below. 


Stack Deflection OutputsThe "stack" tab of the worksheet contains data tables describing the stack deflection. Stack deflection is computed for both Shim ReStackor and ReStackor pro calculations. Data on the "stack" tab is simply a table describing the deflection of each shim in the stack as a function of radial position as computed by ReStackor FEA calculations. The table consists of:
The ReStackor FEA analysis solves up to 5,000 simultaneous equations to balance the radial and axial forces in the stack. The force balance determines the overall stiffness of the stack and forces necessary to close any crossover gaps in the stack. More details are given on the ReStackor force balance page.
Data in the above table is far more interesting when viewed as a plot. ReStackor run with: 0; 100 and 200 lbs force applied to the stack face produces the sequence of plots shown below. The plots help visualize the stack structure and the effect of stack changes such as clamp, taper, or crossover gaps on deflection and the shape of the stack stiffness curve.


Shim ReStackor OutputsShim ReStackor outputs for stack lift as a function of force applied to the stack are loaded onto the "ReStackor" tab of the spreadsheet whenever you hit the "Load_Output" macro button. Shim ReStackor outputs are in columns A through E. ReStackor pro outputs are in columns G through Q.
Shim ReStackor Calculation Outputs, columns A through E:
ReStackor calculations are initiated with zero force applied to the stack. Stack deflections are computed with progressively higher force levels applied to the stack face shim up to the maximum force specified by the input parameter F.stack. ReStackor increments the force using a logarithmic function focusing more points at low force to accurately describe cracking open of the shim stack. Data from the above table is used to construct the Shim ReStackor deflection plots shown on the Plots tab of the workbook.


ReStackor pro OutputsReStackor pro results are loaded into columns G through M whenever you hit the load output button. The fluid dynamic calculations of ReStackor pro compute the forces and flow losses through the fluid circuits and damping force produced by the shock as a function of shaft velocity. ReStackor pro fluid dynamic calculations compute damping force as a function of shaft velocity. Definitions of the ReStackor pro output parameters in columns G through Q:
