Abstract
For the construction of a bolt-clamped Langevin type longitudinal transducer, the resonance conditions, design method for the clamping-bolt and the statics-stress distributions in the PZT element clamped by the bolt have to be studied. Resonance frequencies are successfully estimated with more than an accuracy of 95%, by using the resonance conditions obtained from the analogy if transmission line analysis. Available diameters of the clamping-bolt are also obtained with regard to both the length of the metal block and the diameter of the transducer, by calculating the stress distribution. These diameter calculations have been experimentally proved resonable.
