05-04: Natural Frequency Characteristics of Drive Shafts Fills The main target of these

The main target of these R&D efforts was and is the improvement of the evenness of water distribution in cooling towers and consequentially the overall cooling performance

This paper will review the normal design considerations encountered in designing custom built cooling tower systems with critical demands and will elaborate to include the special design considerations necessary for “Mission Critical Cooling Facilities

It also shows the dramatic effect that mounting has on commonly used high frequency measurements such as Spike Energy and PeakVue that are used for early warning of bearing and gear faults

” Such considerations include building codes

These alternate tube designs were analyzed under a variety of flow conditions in controlled settings

05-04: Natural Frequency Characteristics of Drive Shafts Fills The main target of theseFor rotating machinery utilizing drive shafts, it is important to operate at a speed sufficiently lower than the drive shaft's natural frequency to prevent destructive vibration. In this paper, the theory of determining the shaft's natural frequency is presented as well as methods for empirically testing a shaft's natural frequency. Vibrations levels in the region of the natural frequency are empirically determined for composite drive shafts and
