Als direkte Konsequenz gelingt der Lehransatz bei diesen Studierenden nur bedingt. Wir haben uns als fachübergreifende Learning Community zum Thema „Inverted Classroom“ zum Ziel gesetzt, diesem Phänomen mit einem Maßnahmenkatalog für Lehrende zu begegnen. Um den Maßnahmenka- talog zu entwickeln, wurden anhand von Erkenntnissen aus dem Bereich des Gesellschaftsspieldesigns motivationale Faktoren identifiziert, die die Teilnahme an der Präsenzveranstaltung beeinflussen könnten. Hieraus wurden Maßnahmen abgeleitet, die teilweise bereits in Fächern der Elektrotechnik und der Mathematik umgesetzt wurden. Der Artikel fasst die bisherigen Aktivitäten und Ergebnisse der Gruppe zusammen und stellt den Maßnahmenkatalog vor.

The load distribution on several tooth flanks enables the transmission of high torques. The worm shaft is made of case-hardened steel and the worm wheel of a bronze alloy to avoid scuffing in the tooth contact due to high temperatures in the contact area. Since the wheel is made of a softer material, the gear units usually fail due to damage of the wheel. Common causes of damage are wear, pitting or fracture of a wheel tooth or the entire rim. According to the state of the art, the worm shaft is mostly designed against deflection. In the further literature, cases of tooth breakage of worm shafts are also documented. By modifying the gear geometry or using higher strength materials for the worm wheel, the worm shafts may fail due to force or fatigue fracture under high loads. The accuracy of the gear assembly also has a significant impact on the load distribution of gear units. Deviations in the nominal positions of the components may cause load increases and accelerate the failure of the gear unit. To estimate the influence of the assembly deviations on the bending stress in the worm shaft, this paper presents an analytical calculation approach for determining the bending stress by considering the notch effect, the notch position and the load pattern and distribution. Finally, the bending stresses caused by various load patterns caused by assembly deviations are calculated and the effect is evaluated.

Sufficiently thick ductile targets are perforated by rigid, nose-pointed projectiles in a ballistic process whose dominant failure mode is ductile hole enlargement. Several recent studies have shown that for perforation process by ductile hole formation, the specific cavitation energy, which reflects the target material resistance to steady hole expansion, is essential for analytical predictions of ballistic limit velocities. The ballistic limit velocity is the minimum impact speed that is required for complete perforation of a given target by a given projectile. A logarithmic formulation for the specific cavitation energy of metal targets, which is based on the concepts of (spherical cavitation) effective yield stress and hole slenderness ratio, is shown in several recent studies to be very useful for analytical predictions of ballistic limit velocities. The logarithmic formulation for the specific cavitation energy is presented, and the concepts of cavitation effective yield stress and hole slenderness ratio are reviewed and discussed regarding their importance for accurate analytical predictions of ballistic limit velocities. The present article is a review of these two concepts and their usefulness in perforation mechanics.

They are used in a variety of industrial applications due to large gear ratios and high transmittable torques. The high sliding ratio in the tooth contact requires a hard/soft material combination that is insensitive to scuffing. Worm shafts usually are made of case-hardened steel and worm wheels of a copper-tin-bronze alloy. Since damage predominantly occurs at the wheel (pitting, wear, tooth fracture, etc.), a wide range of calculation methods for load capacity and service life were developed. Regarding the worm shaft, only the deflection is examined, because high displacements of the shaft shifts the contact pattern, which leads to transmission errors and may lead to increased wear. Common calculation methods, e.g. according to DIN 3996 and ISO/TS 14521 provide a good approximation of the deflection. However, simplifications are made in favour of the manageability of the calculation method. Geometric modifications on the worm such as reduced tooth thickness or different lead angles cannot be taken into account with common methods. In order to close this gap, a new approach was presented by Norgauer in 2021, however, significantly overestimating the stiffening effect of the gearing in some cases by neglecting the helical winding of the worm teeth. For efficiency-optimal design of minimally thin worm shafts, approaches that go beyond the deflection are also missing. Investigations by the authors on worm gears using the finite element method (FEM) show a deviation of the bending line of worm shafts from the common calculation methods. The FEM calculations simulate the tooth meshing under load by a driving torque on the shaft, whereas the standard calculations simplify the load distribution on the worm shaft as a radial force introduced at a point. In addition to the magnitude of the radial forces, the axial tooth force component was identified as an influence factor on the bending line since it causes a displacement of the maximum bending location. Especially for increasing diameter factors the displacement of the bearings under load must be taken into account since they may be in the same range as the deflection. Furthermore, the helical winding of the teeth around the shaft leads to an average stiffening effect of the gearing. The cross-section depends on the gear meshing position and causes a periodic fluctuation of the area moment of inertia and a wobbling motion of the shaft. The changing load distribution on several teeth causes a periodic change of the lever arms and an additional dependence of the deflection from the mesh position. An analytical calculation method for the deflection of worm shafts is proposed. It aims at the precise calculation of the spatial expression of the bending line, extends the commonly used simplified model and takes the newly identified factors into account. The bending lines in both radial directions are considered separately. The values of the new introduced factors are derived from the FEM results. Finally, the calculated bending lines are compared with the FEM results and verified.
