Optimization technique has been applied to designing the torsional vibrators with complicated requirements. The torsional transducer of step formed and uniform types for a mechanical filter are designed to satisfy such constraints that their equivalent inductances and capacitance ratios as well as resonant frequencies satisfy the required values. As for a step formed torsional resonator, the dimensions are determined easily by this computer method so that its weight is minimum and its resonant frequency satisfies the required value precisely under keeping the spurious frequencies of the flexural 1st and 2nd modes away far from the torsional resonant frequency by required interval. An important point for effective application of this technique to designing the electro-mechanical vibrator is that the formula for its resonant frequency is substituted into the objective function by eliminating a design parameter of one dimension, because the resonant frequency condition is a serve constraint. One designing is accomplished for only about 10 seconds by a normal sized computer. These designed values are compared with the measured ones and are made sure experimentally to satisfy the required values. This paper concludes that the optimization technique is very useful to design the electro-mechanical vibrators.
