SP 5 - Corrected mean line load value shown in graphic comments
In the face load factor and gap graphics after the face load factor calculation, the mean line load value shown in the comments didn't consider the load factor correctly.
SP 5 - Face load factor graphics not shown correctly when a load spectrum bin has no torque.
The face load factors would show incorrect curves when one of the load spectrum bins had no torque.
SP 5 - Facewidth ratios added to planetary rough sizing results
Facewidth ratios b/d1, b/mn, and b/a have been added as columns in the rough sizing results.
SP 5 - Improvements in the fine sizing functionality
When hobbing cutter is selected in tab Reference profile and then used in fine sizing, the tool is now correctly transferred from fine sizing to tab Reference profile. If cutters from database are used for fine sizing, they are now also correctly transferred to tab Reference profile.
SP 5 - Increase root stress by 1/0.7 for negative (positive) load bins
When writing load spectrum results in the special .rps report, the option "Increase root stress by 1/0.7 for negative (positive) load bins" is now considered correctly for SF and σF in case the option was applicable. Additionally, the displayed damage values are also shown correctly in the .rps report.
SP 5 - Load factor for single bin using inclination and deviation correctly
If a single bin is chosen for the strength calculation, the resulting inclination and deviation for the proportional misalignment is now considered.
SP 5 - Planetary face load factor calculation improved to correctly consider planet angle
The planetary face load factor calculation has been changed to improve the calculation of bending for arbitrary planet positions when shaft files are specified.
SP 5 - Report and graphics show the correct mean line load and equivalent misalignments for face load factor calculation
The reports and graphics for the face load factor calculation now show the correct values for mean line load and equivalent misalignments regardless of load factor settings.
SP 5 - Warning message when carrier torque direction does not match the sign of planet pin deformation
When accepting planetary misalignment settings, a warning is shown to the user if the direction of torque on the planet carrier does not match the sign for the planet pin deformation (dt).
Cylindrical Gears Contact Analysis
SP 5 - Error message shown for contact analysis calculations which do not converge
In cases where the contact analysis does not converge for any step, an error message is shown and the results show inconsistent.
SP 5 - Show frequencies of transmission error amplitude spectrum in the contact analysis report
The frequencies of each harmonic order are added to the contact analysis report for the transmission error amplitude spectrum.
Bevel Gears
SP 5 - Bevel misalignment results corrected when load free pattern was selected
The generated EPG values were represented incorrectly when the load-free contact pattern option was also selected. The results now give the correct values regardless of the settings.
SP 5 - Contact analysis problem in case cutter radius rc0 was not defined
Contact analysis calculation is improved in case when cutter radius rc0 is not defined properly.
Face Gears
SP 5 - Face gear 2D geometry generation
The tooth thickness tolerance is now considered properly for the 2D geometry of the face gear.
Plastics Manager
SP 5 - Tooth root stresses according to VDI 2736 (YF method C) and DAT file for Delrin 100CPE
The tooth root stresses according to VDI 2736 (YF method C) are now correct in the exported DAT file. Until now, the tooth root stress according to VDI 2545 (YF method C) were used. Additionally the DAT file for Delrin 100CPE is updated with the correct values for the tooth root stress.
Shafts
SP 5 - Interpolation of surface treatment factor between the table values
The surface treatment factor will be iteratively calculated, so that the value doesn't change erratically. The definition of the surface treatment factor KV will be executed with the outer diameter no longer with the raw diameter.
SP 5 - Shaft convergence in case of shafts with several inner and outer contours with non-rounded lengths of high precision In some rare cases when shaft consists of several inner and outer contours with non-rounded lengths of high precision the shaft calculation didn't converge.
Bearings
SP 5 - Cylindrical roller bearings with axial fixation
Improved messages when using cylindrical roller bearings with incorrect axial fixation.
SP 5 - Graphics for pressure curve in case of double row rolling bearing with proprietary geometry
When showing graphics of pressure curve for double row rolling bearing with proprietary geometry results for both rows were Descriptionted for the same number of sections. Now one row has negative section numbers and the other one positive, i.e. the same as roller length in case of non-proprietary rolling bearing geometry.
SP 5 - Rolling bearing displacement in rolling bearing report when considering calculation with load spectrum.
When considering calculation with load spectrum the results for rolling bearing displacement in rolling bearing report were given in millimeters instead of micrometers.
SP 5 - Rolling bearing subsurface stresses on inner ring
Calculation of subsurface stresses on inner ring has been revised so that stress σz on the surface equals Hertzian contact stress.
SP 5 - Updated bearing geometry for few Koyo needle roller bearings
Few needle roller bearings from Koyo have updated inner diameter, outer diameter and width.
Shaft-Hub Connections
SP 5 - Hub strength values for splines calculation with K1 factor improved
For the hub, the strength values Rm and Rp for splines were always calculated with an K1 factor of 1.
SP 5 - Hub tip diameter for GO for gauges
Hub tip diameter da for GO gauges according DIN 5480 is improved in the special report.
SP 5 - Multiple interference fit mean pressure calculation
For multiple interference fit, the mean pressure is now calculated more precisely.
Bolts
SP 5 - Calculation of MAmin from input MAmid
The value for MAmin is recalculated from the MAmax and MAmid, when MAmid is an input.
SP 5 - Diameter dw for the M4 bolt according DIN EN ISO 4017
The diameter dw for the M4 bolt according to DIN EN ISO 4017 is now correct.
SP 5 - Multibolt table sizing function
When calling the sizing function for the Multibolt table, the first three rows were not updated correctly.
SP 5 - The tightening technique method 'Hydraulic non-frictional and torsion-free tightening' improved
The tightening technique method 'Hydraulic non-frictional and torsion-free tightening' is improved, so that the torsion has no influence on the calculation.
SP 5 - Unused material types excluded
Material types that are not included in the current material database are excluded from the selection box.
Springs
SP 5 - Tolerances according to DIN EN ISO 6931-1 and DIN EN 10218-2
The tolerances for the allowances according to the DIN EN ISO 6931-1 and DIN EN 10218-2 were not read correctly for tension and leg springs.
Proof of Strength with Local Stresses
SP 5 - Protective layer factor for wrought aluminum alloys
Protective layer factor for wrought aluminum alloys improved according to the FKM guideline.
Scripting

Interface to Autodesk Inventor 2024 is added



KISSsoftis a modular calculation program for the design, optimization and verification of machine elements according to international standards. The individually customized software packages for a wide variety of applications guarantee tailor made solutions and the integration to all common CAD software complete the product.
TheKISSsoft release 2022provides numerous innovations - amongst others, in order to include the tooth fatigue limit in the verification, the information can be generated from time series. The determination of load spectra from time series (torque-speed-time) is now an independent module ("Load spectra"), which can be used to calculate load spectra for gears and for shafts/bearings. In addition to detailed reports, many graphics are now available for displaying the results. Positive and negative torques result in alternating load in the tooth root. The Rainflow method is used to de-termine the number of cycles with a shift from high to low torque. Based on this, the alternating bending factor YM, according to ISO 6336-3 (extended), is determined additionally for the load spectrum in the gear calculation of each element.
