Altering inherent frequency of spring system - involves using plate spring with externally operated member

摘要

The method of altering the inherent frequency of a spring-mass system consists of using a plate spring (1) consisting of a compression member (2) and a tension member (3) joined by at least one of their two ends (4,5). An externally operated expander (6) is positioned between the two ends (4,5) and alters the internal gap (h) between them. The mechanical expander (6) is in the form of an adjusting cylinder (6). USE/ADVANTAGE - The sprung rigidity of the plate spring is adapted in relation to the tensional, compressive and/or flexural stress.
