Abstract

Free vibration analysis of ducts is the first step to understand the coupling between structural and acoustic modes in Heating, Ventilation and Air Conditioning (HVAC) ducts. This thesis covers free vibration analysis of different duct shapes like rectangular, circular, flat oval and elliptical. These types of ducts are extensively used in HVAC systems. Transfer Matrix (TM) method is used to calculate natural frequencies and mode shapes for rectangular and flat oval ducts with simply supported boundary conditions. Free vibration analysis of cylindrical ducts and curved plates is explained as subsections of flat oval ducts. TM method is only useful for simply supported boundary conditions.
