Summary

Dynamic behaviour of the ring subjected to distributed impulsive load is investigated. The ring is represented by the centroidal line and the problem is solved one-dimensionally. Impulsive load is assumed to be the step function with respect to time. The effects of shearing force and rotatory inertia to dynamic load factors with respect to axial force and bending moment are studied.

From the results of theoretical analysis, it became evident that shearing force and rotatory inertia can not be neglected in such a problem as this, and that shear coefficient varies remarkably by the dimensions of the ring and the loading conditions.

Übersicht

Es wird das dynamische Verhalten eines Ringes untersucht, der einer verteilten Stoßlast unterworfen ist. Der Ring wird durch seine Mittellinie ersetzt, so daß das Problem als eindimensional behandelt werden kann. Die Stoßlast wird als Sprungfunktion bezüglich der Zeit angenommen. Die Einwirkungen von Schubkräften und Drchträgheit auf die dynamischen Lastfaktoren werden für Achsialkraft und Biegemoment untersucht. Die Ergebnisse zeigen, daß Schubkräfte und Drehträgheit nicht vernachlässigt werden dürfen. Ferner zeigt sich, daß der Schubbeiwert stark von den Ringabmessungen und den Belastungsbedingungen abhängt.
