Method for arranging multiple vibration isolators and vibration isolation device

Abstract

The invention discloses a method for arranging multiple vibration isolators. In the method, an equipment installation platform is arranged according to the gravity of each equipment in an equipment set and the arrangement of the equipment in the equipment set, and then the model, the number and the arrangement of the vibration isolators are determined, so that the equivalent action point of the composite force of the supporting forces of all vibration isolators and the gravity center of a whole body comprising the equipment set and the equipment mounting platform are positioned on the same vertical straight line; and the support force of each vibration isolator is 95 to 105 percent of the rated load of the vibration isolator. A vibration isolation device according to the method for arranging the multiple vibration isolators comprises the equipment mounting platform for mounting the equipment set, a positioning plate connected with a foundation platform and the vibration isolators arranged between the equipment mounting platform and the positioning plate. The method is characterized in that the equivalent action point of the composite force of the supporting forces of all vibrationisolators and the gravity center of the whole body comprising the equipment set and the equipment mounting platform are positioned on the same vertical straight line and the support force of each vibration isolator is 95 to 105 percent of the rated load of the vibration isolator. The number of the vibration isolators is not less than eight and the number of the models of the vibration isolators is one or two.

Description

technical field [0001] The invention belongs to the field of vibration control, and in particular relates to a method for arranging multiple vibration isolators and a vibration isolation device. Background technique [0002] The vibration isolation device is a device that isolates the vibration effect between the power equipment and the foundation platform. Usually, the power equipment and its installation components are supported on the foundation platform through vibration isolation devices. Among them, the vibration isolator is a key component that determines the vibration isolation performance of the vibration isolation device. [0003] The number of vibration isolators included in a conventional vibration isolation device is based on the principle of stability. Generally, there are four vibration isolators of the same type, which are respectively installed at the four corners of the vibration isolation device. When there are multiple or multi-type equipment installed ...

AI Technical Summary

Problems solved by technology

When there are multiple or multi-type equipment installed on the equipment installation platform, since the center of gravity of the equipment group and the equipment installation platform as a whole and the geometric center of the equipment installation platform are mostly not located on the same vertical line, the actual load of each vibration isolator Usually inconsistent, on the one hand, this may cause the actual load of some vibration isolators to deviate from the rated load, reducing its vibration isolation performance; on the other hand, different actual loads show that the deformation of each vibration isolator is also different, which means It will cause the equipment installation platform and the equipment group on it to incline, and then impose a load other than the main bearing direction on the vibration isolator, which not only reduces the vibration isolation performance, but also reduces the service life of the vibration isolator
