Summary
Vibrations of a stiffened annular sector plate with arbitrary boundary conditions are analysed using the spline element method. The plate is idealized as a system of an annular sector plate and curved beams rigidly connected to each other. To demonstrate the accuracy of the present method several examples are solved, and the results are compared with those obtained analytically and by other numerical methods. Good accuracy is obtained. The effect of stiffening beams on the frequencies of stiffened annular sector plates is also investigated.
Übersicht
Die Schwingungen versteifter Sektorplatten werden mittels der Spline-Element-Methode untersucht. Die Platte wird als ein System von Sektorplatte und gebogenen Trägern idealisiert. An Zahlenbeispielen wird gezeigt, daß bezüglich der üblichen analytischen Methode und numerischen Methoden die genaue Lösung erhalten wird. Der Effekt versteifender, gebogener Träger auf die Frequenzen wird untersucht.
