The effect of polymer coating on acoustic transducer material - design, analysis & optimization
Raja Seshu.T.,  Swami Naidu.G.
This paper aims at design the Acoustic transducer to withstand high pressures. Transducer is layered with Natural rubber, Neoprene, Nitrile rubber and Polyurethane and selects the suitable polymer among them in order to withstand high pressures. In general under sea water 1bar pressure increases to every 10 meters depth. Hence the performance of transducer varies with depth of water and pressure. The function of Acoustic transducer is receiving and sends the acoustic signal. Different types of transducers made of PZT’s (lead zirconate-titanate) and Ceramics etc are available in the market for underwater applications. Because of good acoustical properties Clay poled ceramic material has been used for transducer instead of PZT’s. As per ASTM D 3182 standards Polymer material specimen is taken and tensile strength test is conducted, and generates the stress versus strain curve. The uniaxial test data is necessary for Hyper Elastic curve fitting to evaluate the C01, C10 constants. CATIA V5R20 software is used for modeling and ANSYS 17.0 version is used for analysis. Mate lab program is used for determining stresses at other thicknesses. Among the four polymers Nitrile rubber is suitable for Acoustic transducer design to withstand high pressures.
