Suspension vibration isolation structure

Abstract

Disclosed is a suspension vibration isolation structure. The suspension vibration isolation structure is composed of hanging type damping spring vibration isolators, constrained damping components, a vibration isolation platform and rubber dampers, wherein the hanging type damping spring vibration isolators are mounted onto a roof construction structure, the vibration isolation platform is arranged at the bottom of the screws of the hanging type damping spring vibration isolators, a vibration device is mounted on the vibration isolation platform through the dampers, and the constrained damping components are arranged between the hanging type damping spring vibration isolators and the screws above the vibration isolation platform. Every constrained damping component is composed of a constrained damping unit, a direction regulating connector, the screw and an adjusting bolt and can be arranged in the vertical plane around the vibration isolation platform in a cross mode or among the three-dimensionally opposite corners of the vibration isolation platform in an oblique cross mode; the cross point of the screws between every two constrained damping components is fixed through a steel rope clamp. The suspension vibration isolation structure can effectively control the resonant rocking of suspended vibration equipment and meanwhile control the vibration transmission of the vibration equipment and is simple in structure, low in cost and easy to assemble.

Description

Technical field [0001] The invention relates to a vibration control technology, in particular to a suspension vibration isolation structure capable of blocking vibration transmission of a suspension vibration device. Background technique [0002] In the process of installation of engineering equipment, there are often various suspended vibration pipes, fans, static pressure boxes and suspended high-altitude vibration equipment that need to be suspended and damped. At present, more is the use of damping hooks. The vibration damping hook has a simple structure and is very effective in damping treatment of various pipes, fans, air ducts and air pipes. However, due to the single natural frequency of the suspended damping spring isolator, the torsional damping torque will produce a reverse force for the suspended vibration equipment in the decelerating rotation process. When the excitation frequency gradually approaches the natural frequency of the equipment system, When resonance o...

AI Technical Summary

Problems solved by technology

However, due to the single natural frequency of the suspension damping spring isolator, the torsional damping moment will produce a reverse force when the suspended vibration equipment is in the process of deceleration and rotation. When the excitation frequency gradually approaches the natural frequency of the equipment system, resonates, the amplitude will increase

Since the suspended equipment system is elastically suspended, the rigidity is poor. If the equipment system is unbalanced, it will shake and cause damage to the connection between the vibration equipment and the equipment system.

At the same time, the vibration isolation effect is not ideal
