Parameter-adjustable liquid-elastic vibration isolation device

Abstract

The invention provides a fluid elastomer type isolation mounting with adjustable parameters. The isolation mounting comprises a cylinder barrel, a welded bellows, a principal mass, a rubber ring and asuspended mass. The welded bellows, the principal mass, the rubber ring, the suspended mass and the cylinder barrel are coaxially arranged; one end of the welded bellows is hermetically provided withthe suspended mass, and the other end of the welded bellows is fixed to the bottom of the cylinder barrel; and the principal mass is connected to the cylinder barrel through the rubber ring, and usedfor driving hydraulic oil in the cylinder barrel to reciprocate linearly. According to the isolation mounting provided by the invention, through improving the traditional dynamic anti-resonance structure, the disadvantages of complex structure and uneasy adjustment of the traditional dynamic anti-resonance structure are overcome.

Description

technical field

[0001] The invention relates to the field of engineering structure vibration isolation, in particular to a parameter-adjustable liquid-elastic vibration isolation device. Background technique

[0002] Vibration control is a common problem in engineering field. Vibration widely exists in daily life, from railways to buildings, from automobiles to ships, to aerospace, etc., vibration problems are everywhere. Vibration not only affects the service life of mechanical equipment, the performance of instruments and equipment, and the normal work of operators, but also causes damage to building structures. But also affect the vitality of ships, aircraft and their combat technical performance, and even affect people's health.

[0003] Vibration control methods generally include: reducing the excitation of the vibration source, preventing resonance and vibration isolation. These methods can be realized through active control technology, semi-active control technolog...
