LOW FREQUENCY RING RESONATORS SIXTH AND SEVENTH QUARTERLY PROGRESS REPORT COMBINED-FOR PERIOD DECEMBER 25, 1952 TO MARCH 25, 1953 AND MARCH 25, TO JUNE 25, 1953

摘要

Design equations are presorted for the fabrication of rings with a desired frequency and turnover point of the frequency-temperature characteristic.nA relationship is shown connecting the performance of flexural vibrators operating at fundamental and overtone modes.nA brief investigation of several flexure nodes is made in an attempt to find vibrators having a practical physical size for a desired temperature-frequency characteristic. Approximate frequency equations for these flexural vibrators are included. These are obtained by the method of Rayleigh.nA discussion of the characteristics of tuning-forks and cantilever vibrators is presented;and their structural and performance advantages are coopered to a 1 EC ring vibrator having a room temperature vertex of the temperature-frequency characterization.
