Advanced Spring Design - Automatic Update: Release 7.10
Effective Date: Dec 29, 2010
Existing ASD customers: updates will automatically be downloaded upon program start-up.


Updates in ASD release 7.10:

ALL Spring Types:
  • Fixed a bug in the DXF image generator which caused ASD to crash after subsequent operations.

Extension Springs:
  • Fatigue life calculations/plots updated.
  • End types modeled more accurately on the input/output form (not yet in the illustrations).

Torsion Springs:
  • Natural frequency formula updated to use active coils instead of only the body coils.
  • Free angle tolerance added.

Conical Springs:
  • For two conical springs in series, transition coils pitch can now be independent of the pitches on each end.

Power Springs:
  • Prestressed spring calculations updated.
  • Plot labels updated.
  • Variable descriptions improved.

Compression Springs:
  • Pitch angle now works the same as pitch as an input in iterative calculations.

Conical Compression Springs:
  • Free length and solid length calculations updated for telescoping springs.

Belleville Washers:
  • Fixed a report bug involving the free height units.

Extension Garter Springs:
  • Improved the flexibility and accuracy in modeling the connection of the ends.

Advanced Spring Design - Automatic Update: Release 7.09
Effective Date: Jul 15, 2010
Existing ASD customers: updates will automatically be downloaded upon program start-up.

Updates in ASD release 7.09:

Power Springs:
  • Updated and tested the Power Spring formulas based on those from A. M. Wahl’s Mechanical Springs book.

Wave Washers:
  • Default value appeared for the washer OD if the ID is given. Fixed in model now.

Torsion Springs:
  • Dimensional scenario now has Total Coils as a green box.
  • Arbor diameter added to the interface.

Extension Springs:
  • Arbor diameter added to the interface.

Conical Springs:
  • Rate infeasibility check was not sensitive enough.
  • Changed the quick start fields.
  • Improved initial guesses for common scenarios.
  • Report was poorly formatted near the index values.
  • Report was crashing if the rate plot was selected.

Rectangular Torsion:
  • Optional inputs were not working.

Interface:
  • A message is now displayed when the solver is unable to converge to a feasible solution.

Advanced Spring Design - Automatic Update: Release 7.08
Effective Date: May 18, 2010
Existing ASD customers: updates will automatically be downloaded upon program start-up.

Updates in ASD release 7.08:

Profiles:
  • File - Profiles caused an error box to appear.

Plots:
  • An extra line was appearing on a few plots.

Extension Springs:
  • Program was reporting negative deflections if loads were less than initial tension.

Conical Springs:
  • Backsolving for a small number of active coils sometimes diverged. A better initial guess is now used.

Garter Springs:
  • Fixed report page width.

3D Rendering:
  • Dead coils now correctly shown on both ends of the spring.
  • Warning message for springs with more than 200 coils for the report.
  • An option is now provided to suppress the thumbnail graphic on the report.

Reports:
  • Email button added to standard report.
  • Wording changed to clarify cycle loads.

Torsion Springs:
  • Plots would not appear if just one load was supplied.
  • Refined the iterative process to solve for wire size given max torque conditions.
  • Body diameter tolerance for rectangular wire springs updated to use the proper dimensions for the required spring index calculation.

Interface:
  • Use of commas instead of decimal points caused problems for users with European settings.

Advanced Spring Design - Automatic Update: Release 7.07
Effective Date: Mar 04, 2010
Existing ASD customers: updates will automatically be downloaded upon program start-up.

Updates in ASD release 7.07:


Conical Springs:
  • Improved error trapping prior to iterative calculations so that ASD doesn't just "go blank"
  • Improved the accuracy of the free length and solid length calculations.
  • Fixed a problem involving an "Inconsistent" message that should not have been triggered.

Spiral Torsion Springs:
  • Plots were not getting displayed.

Torsion Springs:
  • Arm angles at the "set" condition were not from 0 to 360 if the deflection was > 360.
  • Coil diameters can now be solved for if the wire size is not given.

Springs in Parallel:
  • Diametral spacing equations were kicking in even if the setting was turned off.

Interface:
  • DXF text height was not displaying properly when units were switched.

TK Solver Player Update: Release 136.1
Effective Date: Apr 20, 2007

TK Player has been updated to take advantage of the new features in the TK Solver Excel Toolkit. See the TK Solver update notes for more details on those features.

TK Player runs applications created using the TK Solver - Excel Toolkit. The Toolkit has recently been enhanced to allow for linking lists of arbitrary lengths. Previously, the list length was set at the time of linking and could not vary as the inputs to the TK model varied. This update removes that restriction. Individuals who had previously downloaded TK Player must download this update to run any new TK Player applications created using this new feature.
