The gear-box of this programme is arranged on above upper frame; In gear-box working procedure, when gear-box is in low-frequency vibration region, flowed between upper and lower chamber by the liquid in hydraulic mount, low-frequency vibration energy is dissipated as early as possible, thus realize the object of gear-box being carried out to vibration damping in the vibration of low frequency region.
When gear-box is in medium-high frequency vibration area, the liquid in hydraulic mount circulates hardly, and now hydraulic mount accelerates the attenuation process of dither by the elastic deformation characteristic of decoupling zero sheet; The more important thing is, obtain due to the chamber in intercommunication vibration the first tuning pipeline of tuning unit and second tune pipeline communication two hydraulic mounts through overtesting, thus can by the liquid in the first tuning pipeline and second tune pipeline communication two hydraulic mounts, a part of dither in two hydraulic mount chambers is cancelled out each other, thus effective raising carry out vibration damping and isolation effect to the vibration of gear-box in medium-high frequency region.
Further, because the vibration of the bottom chamber of hydraulic mount is through overdamping, thus the upper chamber of same hydraulic mount is different with the vibration frequency of bottom chamber, there is certain otherness; And the Single port of first of this programme the tuning pipeline is connected with the upper chamber of a hydraulic mount, another port is connected with the lower chambers of another hydraulic mount (namely the upper chamber of hydraulic mount communicates with the lower chambers of another hydraulic mount); The Single port of second tune pipeline is connected with the lower chambers of a hydraulic mount, and another port is connected with the upper chamber of another hydraulic mount (namely the upper chamber of hydraulic mount communicates with the lower chambers of another hydraulic mount); The otherness of upper chamber and bottom chamber vibration frequency can be utilized like this, the vibration in two hydraulic mount chambers is effectively avoided to superpose, dither in further increase two hydraulic mount chamber is cancelled out each other part, improves the effectiveness in vibration suppression of gear-box in medium-high frequency region further.
On the other hand, although the chamber in the first tuning pipeline and second tune pipeline communication two hydraulic mounts is conducive to improving the effectiveness in vibration suppression of gear-box in medium-high frequency region, but when low frequency, large amplitude excitation, likely produce the superposition of two hydraulic mount chamber internal vibrations, and affect the normal use of vibration damping scaffold.Such as, in low-frequency vibration process, the chamber of a hydraulic mount is in confined state, when the chamber of another hydraulic mount is in and is stretched state, just easily vibrates superposition in the chamber of this two hydraulic mount.Thus, in order to avoid when low frequency, large amplitude excitation, produce the superposition of two hydraulic mount chamber internal vibrations, and affect the normal use of vibration damping scaffold; This programme arranges floating type first self adaption partition apparatus on the first tuning pipeline, second tune pipeline arranges floating type second self adaption partition apparatus, solves this problem.In low frequency, the large amplitude process of motivation, when the chamber of a hydraulic mount in two hydraulic mounts be interconnected is in confined state, when the chamber of another hydraulic mount is in and is stretched state, due to low frequency, liquid stream momentum in the large amplitude process of motivation in hydraulic mount is large, thus liquid in the chamber of the hydraulic mount of confined state is in by toward the chamber indoor moveable of hydraulic mount being in the state of being stretched, when a large amount of liquid stream is through the first tuning pipeline or second tune pipeline, floating type first or the partition end plate of floating type second self adaption partition apparatus will move toward annular lug under fluid driven, and be resisted against in O-ring seal, thus cut off the first tuning pipeline or second tune pipeline, avoid the superposition of two hydraulic mount chamber internal vibrations, ensure that vibration damping scaffold is at low frequency, normal use in the large amplitude process of motivation, and when dither region, the liquid in hydraulic mount circulates hardly, thus there is not this problem.
