Natural Frequencies of Plate Supported Thermowells

Journal of Pressure Vessel Technology, 2015
An idealized model of a welded-flange thermowell is used to establish the role of flange thickness in natural frequency estimates. It is found that for thermowell diameters comparable to flange thickness, the support compliance of the thermowell/flange interface approaches that expected for a semi-infinite support.

An External Memory Supported ACO for the Frequency Assignment Problem

2005
Ant colony optimization algorithm is integrated with an external memory for the purpose of improving its efficiency for the solution of a well-known hard combinatorial optimization problem. The external memory keeps variable-size solution segments extracted from promising solutions of previous iterations.

Natural Frequencies Formula for Simply Supported Mindlin Plates

Journal of Vibration and Acoustics, 1994
This paper presents an explicit formula for the vibration frequencies of simply supported Mindlin plates in terms of the corresponding thin (Kirchhoff) plate frequencies. The formula has been obtained from an exact vibration analysis of simply supported rectangular Mindlin plates. When the formula was applied to other simply supported plate shapes such

Natural Frequencies of Nonuniform Beams on Multiple Elastic Supports

Journal of Applied Mechanics, 1958
Abstract A method is presented for the determination of the natural frequencies of nonuniform beams on two or more torsionally and linearly elastic supports, including the effect of rotary mass moment of inertia. The method employed is an extension of the Myklestad method.
