Problems solved by technology

However, this shock absorber has the following disadvantages: (1) the magnitude of the induced current generated by the induction coil is limited, that is, the electromagnetic damping force it can provide is limited; And the magnetic field generated by the induced current increases the damping of the system, but the damping force does not change with the change of the external excitation frequency, which sacrifices the system in a stable working state (the ratio of the excitation frequency to the natural frequency of the system is greater than ) vibration isolation efficiency

Embodiment Construction

[0021] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] Such as figure 2 and image 3 As shown, a spring vibration isolation device based on adaptive electromagnetic damping implemented according to the technical solution of the present invention includes: a metal antimagnetic sleeve 1, an outer cylindrical hollow permanent magnet 2, a load platform 3, and an inner cylindrical hollow permanent magnet 4. Helical spring 5, coil 6, displacement sensor 7, microprocessor 8, current flow converter 9, variable resistor 10, DC power supply 11, base 12 and other components. Among them, the metal antimagnetic sleeve 1 is open at both ends, the lower end is fixed on the base 12, and the upper end maintains a certain gap with the load platform 3 to prevent the inner and outer cylindrical hollow permanent magnets 4, 2 from being affected by the magnetism of the outside world. The inner and outer cylin...

Abstract

The invention discloses a spring vibration isolating device based on self-adaption electromagnetic damping. The spring vibration isolating device comprises a shell, a loading platform above the shell, a radial magnetic field generating unit in the shell, an electromagnetic damping generating unit in a radial magnetic field and a spring vibration isolating unit supporting the loading platform. A processing unit and a detecting unit sensing outer exciting force borne by the loading platform are further included. The processing unit controls the starting state of the electromagnetic damping generating unit according to an outer exciting force signal sensed by the detecting unit, and the direction and degree of electromagnetic damping force acting on the spring vibration isolating unit are generated. The invention further discloses a vibration isolating method based on the device. The self-adaption electromagnetic damping force is provided for the spring vibration isolating unit, and under the condition of keeping the low fixed frequency of the spring vibration isolating device, the vibration isolating requirement under different work conditions (different exciting frequencies) can be met by a vibration isolator.

Description

technical field [0001] The invention belongs to the field of environmental vibration and noise control, in particular to a spring vibration isolation device and vibration isolation method based on adaptive electromagnetic damping. Background technique [0002] The impact of vibration and the secondary structure noise caused by it on the surrounding environment is mainly accomplished through vibration transmission. Isolating the transmission of vibration or increasing the transmission loss of vibration can effectively control the vibration and its secondary structure-borne noise effects. At present, in vibration control projects such as equipment and rail transit, the most widely used vibration control measure is to install vibration isolators under the vibration equipment. The vibration isolation effect of a reasonably designed vibration isolator can reach more than 85% to 90%. [0003] The main indicators affecting the vibration isolation performance of the vibration isola...
