Hydraulic damper Hydraulic damper / 2247269
Hydraulic damper comprises piston provided with axial passages and working cylinder filled with fluid. The piston is connected with the rod. The inner side of the cylinder and outer side of the cylinder, which is in a contact with the piston side, are provided with thread. The piston is mounted on the rod for permitting rotation around the rod. The piston is provided with radial passages whose longitudinal axes intersect with the longitudinal axes of the axial passages of the piston. The diameters of the axial passages decrease from the longitudinal axis of symmetry of the piston to its periphery. The radial passages receive movable spring-loaded slide valves whose diameters exceed these of axial passages of the piston.

(57) Abstract:

Usage: marine engineering, to reduce vibrations of structures. The inventive Foundation of pillars provided with inner and outer tubular profiles, the gap between them in the upper part thereof is closed by a plug made of a viscoelastic material. The inner tubular profile with the vibration absorber and provided with a cover in the form of a vibration damper, vibration absorber is made in the form of a spiral spring with a flange. Plug gap is made in the form of a sleeve, the upper part of which is connected with tubular profiles. In the gap installed viscoelastic shell, coupled with the sleeve, spring and flange by hot vulcanization. Tubular profiles, shell, and the spring can be made in the form of conical elements, and a tubular profile made of viscoelastic material. The use of the invention allows to improve the vibration properties of the device while increasing operating frequency range from 6 to 10000 HZ due to the emergence of significant shear deformation of viscoelastic shell relative to the springs, and the need to overcome the forces of adhesion resulting from the interaction vibro is 1 Il.

The invention relates to mechanical engineering and can be used to reduce vibrations propagating in structures from on revealing equipment.

Famous adopted as the closest analogue of the marine pillars containing inner and outer tubular profiles, the gap between them in the upper part thereof is closed by a plug made of a viscoelastic material, and the inner profile is filled vibration absorber and provided with a cover in the form of a vibration damper of the Belleville springs (SSSR ed. mon. N 1643311, 1991).

This device reduces vibration up to 10-25 dB only in the mid range and low frequencies from 6 to 1000 Hz and ineffective at high frequencies.

Load characteristic of the device (the dependence of precipitation on the force) is linear, which affects their ability to impact loads.

The aim of the invention is the enhanced operational capabilities pillars through improved vibration damping properties in a wide frequency range from 6 to 1000 Hz, with a simultaneous increase efficiency under the action of shock loads.

This is achieved by, in the famous ship Pillersee vibration absorber is made in the form Mi profiles, in the gap between the tubular profiles installed discourage shell, connected mainly by hot vulcanization with the sleeve, spring and flange.

When this tubular profiles, shell, and the spring is made in the form of conical elements, and a tubular profile made of viscoelastic material.

The drawing shows a longitudinal section of a vibration-damping pillars.

Picked pillars contains the inner 1 and outer 2 conical tubular profiles, made of rubber, the gap between which a closed rubber sleeve 3, and a vibration absorber made of twisted conical spring 4 with the flange 5.

In the gap between the tubular sections 1 and 2 equipped with a conical sheath of rubber 6, connected with the sleeve 3, the coils of the spring 4 and the flange 5, for example, by hot vulcanization.

The inner tubular profile partially filled with a vibration-silicone fluid 7.

The device operates as follows.

Static load corresponding to the operating state of pillars acts through the sleeve 3 and the flange 5 on profiles 1 and 2, the spring 4 and the shell 6, kotou spring 4.

Under static load, the device receives a Deposit, when which the coils of the conical spring due to the different diameters have different stiffness, so okazivautsya different: in the first place is precipitated bottom round, then the next height, etc.

Due to the specified property of the conical spring load characteristic of the device (the dependence of precipitation on the force) is nonlinear, which positively affects the action of the shock loads that according to the performed calculations effectively extinguished by the device.

Under the action of load coils of the spring 4 are twisted, resulting in large shear deformations in the rubber layers of the shell 6 and profiles 1 and 2 by vulcanization strongly connected with the coils of the spring 4.

When exposed to vibration or shock loads these deformations are amplified, being circular, which greatly enhances vibraphone device, making it effective in a wide range of frequencies from 6 to 10,000 Hz.

Rubber sleeve 3 under the action of vibration or shock loads varies, its lower part immersed in the silicone fluid fibroplasia loss of vibrational energy. When the action of the shock load, the clearance between the bottom of the sleeve and the surface of the flange 5 is selected, the viscoelastic material of the sleeve is deformed, increasing the nonlinearity of the load characteristics of the device.

The invention extends the capabilities of the vibration-damping pillars due to the nonlinear load characteristics while improving vibration damping properties.
