The new KISSsoft release 2022 provides 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 determine 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.
