METHOD OF CHANGING NATURAL OSCILLATION FREQUENCY OF SHELL STRUCTURE HOUSING Russian patent published in 1995 - IPC

Abstract RU 2039894 C1

FIELD: vibration engineering. SUBSTANCE: method includes changing bending rigidity of the housing owing to setting a hydraulic cylinder between fastening members and its effecting on the housing. Before affecting on the housing, at least one additional hydraulic cylinder is interposed between the fastening members. All hydraulic cylinders are mounted inside the housing in planes lateral to its longitudinal axis. One cylinder is arranged vertically and the other one horizontally. EFFECT: enhanced reliability. 3 dwg
