Abstract:

The research objective has been to evaluate performance of the preliminary baroswitch design. Vibration tests of single elements verify unbalance of contact counterweights also show 1600 c resonance of arm supporting remote set contacts. Operation of baroswitch completely without lubrication appears to be feasible. Fixtures for vibration testing of a complete remotely settable element have been constructed and tests performed. The results of the element vibration test clearly indicate the presence of two resonant frequencies, at 1640 and 2650 c, which are excited by table harmonics at certain fractions of these frequencies. The 2650 c frequency is about what was expected for the diaphragm - contact configuration. The sensitivity of this assembly to low vibration inputs is indicative of poor mass-balance. This unbalance will be corrected by appropriate changes to the counterweights. Author
