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

Abstract RU 2039893 C1

FIELD: vibration. SUBSTANCE: bending rigidity of the housing is changed owing to rigidly securing of fastening members to different ends of the housing. In addition, a hydraulic cylinder is mounted. One end of the hydraulic cylinder is connected with the fastening member secured to the one end of the housing, and the other end with the fastening member secured to the other end of the housing. The hydraulic cylinder effects on the housing. Before effecting on the housing, the fastening members are made up as ring bearings. Three additional hydraulic cylinders are also mounted. All cylinders are arranged in pair in vertical longitudinal and horizontal symmetry planes of the housing diametrically opposite with respect to the later. EFFECT: enhanced reliability. 1 dwg
