KISSsoft - Bearing calculation
SP1 Values in bearing DB were rounded to integer
For some db columns, the values were rounded to integer instead of keeping them as floating point. This could cause some deviations for very small bearings where the rounding error was relevant.
SP1 Inner geometry approximation for needle cages
In many cases the inner geometry approximation for needle cages did not work and resulted in very unrealistic values for the the number of rolling bodies and roller length. With this fix, the estimation based on C and C0 is now very accurate and robust.
KISSsoft - CAD interface
SP1 Autodesk Inventor: Interface to Autodesk Inventor 2019
Interface to Autodesk Inventor 2019 implemented.
KISSsoft - COM
SP1 Improvement: Retrieve number of members in dynamic arrays via COM
It is now possible to get the number of members in a dynamic array via a COM call to the size() function of the variable.
KISSsoft - Gear calculation
SP1 Non-circular gears
In some cases for non-circular gears, error message appeared stating that the file for the operating pitch line of gear 2 doesn't exist. This is now fixed.
SP1 Excitation force calculation deactivated for stepwise contact analysis over COM-Interface
The excitation foce calculation was wrongly activated for stepwise contact analysis calculation over COM-Interface. This was setting results to 0 and is now fixed.
SP1 Planetary system contact analysis was overwriting face load factor results
The planetary system contact analysis was overwriting face load factor results according to ISO 6336-1, Annex E. This is fixed.
SP1 Load spectrum selection switched to own input
The load spectrum switched to own input after changing the reference gear for planetrary gears.
SP1 Modification for mold making
The points in the root area of the gears in the operation of modification for mold making were not calculated correctly. This is now fixed.
The calculated tooth form is now slightly different in the root area.
SP1 Ball diameter for worm gears
In some cases for worm gears (high tooth thickness tolerances, tooth thickness modification factor xs<>0), the theoretical measuring ball diameter was not calculated correctly. This is now fixed.
SP1 Contact analysis had changing results
Contact analysis with nominal load and shafts had sometimes changing results. This is fixed.
SP1 Proportional axis misalignment of planetary system problem
Proportional axis misalignment of planetary system was calculated with the wrong carrier torque in case of ISO 6336-1 Annex E calculation with load spectrum. This is now fixed.
SP1 Calculation example CylGearPair5 changed
The calculation method for example CylGearPair5 was changed from VDI 2545 (YF method B) to VDI 2545 modified (YF method B).
SP1 Sizing power and torque for asymmetric gears
Sizing functionality for power and torque did not work properly for asymmetric gears. This is fixed.
SP1 Modification sizing was crashing for planetary systems
Modification sizing of planetary systems with contact analysis was crashing, this is fixed.
SP1 Improvement: Proposition for optimum profile shift x for scuffing according AGMA925
When any AGMA rating method is selected, the scuffing is calculated according AGMA 925 and is also used in the profile shift proposition tool.
AGMA925 shows as result the scuffing probability. According the standard, if the probability is smaller 5%, then <= 5% must be shown.
Therefore in the layout function for best profile shift x often the result was 5%, therefor not really showing the best value.
We changed this and use now the lowest contact temperature thBMax to find the optimum profile shift.
KISSsoft - General
SP1 Occasional crashes during startup of KISSsoft
On some machines, KISSsoft crashed occasionally during startup. This is fixed.
SP1 Modification sizing had problems showing results
Modification sizing with ISO 6336-1, Annex E, was not showing results correctly and not able to transfer solution into tab modifications. This is fixed.
SP1 Icon for KISSsoft User Interface help added to the toolbar
The icon was only available for internal users.
SP1 Database tool base material search
The search function did not work for the column base material in the material tables in the database tool.
SP1 KUI help did not work in dialogs
Question mark for KUI help added to the title bar of all dynamic dialogs.
KISSsoft - Graphics
SP1 Contact analysis had problem with unequal facewidth
Several contact analysis graphics had problems while calculating gears with unequal facewidth. This is fixed now.
KISSsoft - Root stress FEM calculation
SP1 Too high maximum stress in some cases of root stress calculation using 3D FEM.
The area on the tooth surface used for the calculation of the maximum stress of 3D root stress FEM was for some cases falling inside the load zone, giving very high stresses. This is now fixed.
SP1 Optimization of the mesh generation for 3D root stress FEM, reduce run-time.
The size of the generated 3D FEM mesh is reduced without affecting the accuracy of the results. The calculation time is reduced.
KISSsoft - Shaft calculation
SP1 Layout of element editor for sections
The layout of the element editor for sections and documentation points is improved.
SP1 Fixed drawing artefacts for gear body in shaft editor
When using a stiffness matrix for the gear body, the drawing in the shaft editor showed line artefacts for some configurations.
SP1 Context menu in shaft editor
In some cases, the general context menu was shown for a shaft element instead of the element specific context menu.
SP1 Oil level in shaft editor
The indicator for the oil level was changing its width when the diameter of an element was changed.
SP1 Element editor update issue
A change in the element position was not considered in the calculation if
the calculation button was pressed right after entering the value in the
SP1 IMPROVEMENT: Zoom position in shaft editor changed
When zooming with the mouse wheel in the shaft editor, the center point of the zoom is the current mouse position not anymore the center of the editor.
SP1 IMPROVEMENT: Zoom level in shaft editor
The zoom level in the shaft editor remains the same when switching between tabs.
SP1 Connecting support (joint) positioned at edge position of a shaft
When a connecting support (joint) was positioned at the left edge position of a shaft, the torque balance was not calculated properly.
SP1 Campbell diagram lines were mixed in some problems.
The lines of the Campbell diagram were mixed in some models, due to wrong characterization of the respective eigenmodes. This is now fixed.
SP1 Custom bearing diameters
When a shaft calculation was saved with a custom bearing and opened again
on an instance where this bearing is not in the DB, the
selected diameter was not shown properly.
SP1 Wrong material properties used for calculation of operating bearing clearance
The calculation for the operating bearing clearance did use wrong material properties (inner ring properties for inner shaft and vice versa).
KISSsoft - Shaft-hub-connections
SP1 M02b-M02e: values for support factor fs according DIN 6892:2012
The values for the support factor fs were in KISSsoft according Niemann, we actualized this, now the values are according DIN 6892:2012.
KISSsoft - Splines calculation
SP1 Spline calculation stopped working
In some cases for splines with low number of teeth (<11) and profile
shift exactly 0.05, the calculation stopped working. This is now fixed.
SP1 Wrong text in ANSI table fixed
Even if the ANSI table was showing Normal Diametral Pitch correctly, the text was set to normal module.
KISSsys - General
SP1 KISSsys desktop linkage was not working
The KISSsys desktop linkage was not working because of missing working directory. This is fixed.
