winLIFE 3.4: What’s new ?

 

Interfaces to FEA / MBS

ANSYS

An ANSYS-Interface to ANSYS Classic and ANSYS Workbench exists.

Nx

The new winLIFE data access tool was used to create a data inteface to Nx. This is used by a winLIFE customer.

Tool for flexible data access

To perform a flexible data transfer a tool was designed, which gives fast access to ASCII result files (see next picture).


 

Calculation Methodes / Functionality


- The cosideration of the residuum was modified. In the case of short load histories and huge multipliers the residuum has an important influence for fatigue life. Especially for this the canges may be helpful.

 

- The stress gradient can be used for notch stress concept with FE-Data. It is used to modify the local S-N curve. Since version 3.41 an automatic creation of the related stress gradient will performed.

 

- With the factor sqrt( 1 + findley_k * findley_k) the corner point of the endurance limit is multiplied and when showing the results for the damage accumulations calculation the modified S-N curve is shown together with the transformed loading.

 

- The pre-sign for the mod. GE-hypothesis can be selected according to either the algebraic or amount largest principal stress.

- Load-Time-Functions can be automatically split into negative or positive areas.
This enables to model nonliearities in a linear way.

 

-  Load time data can be squared before using it. In this wy circumeretial forces can be modeled .

Result presentations

-  For the amplitude transformation the modified loads are shown together with the S-N curve.


User comfort



-  When opening a project, all internal paths of the internal winLIFE files are automatically reset. Problem which occured after changing a directory could bve solved.


-  Selecting one of several licenses -> it is no longer necessary to re-enter the password when changing licenses.
