The Single port of described first tuning pipeline is connected with the upper chamber of once hydraulic mount, and another port is connected with the lower chambers of another lower hydraulic mount; The Single port of described second tune pipeline is connected with the lower chambers of once hydraulic mount, and the upper chamber of this lower hydraulic mount is connected with the port of the first tuning pipeline, the another port of second tune pipeline is connected with the upper chamber of another lower hydraulic mount, and the lower chambers of this lower hydraulic mount is connected with the port of the first tuning pipeline.
The wind turbine gearbox of this programme is arranged on scaffold, and wind turbine gearbox is positioned at above scaffold; In wind turbine gearbox working procedure, the vibration of wind turbine gearbox can realize two-way vibration damping by the lower damping element below scaffold and the upper damping element above scaffold.When wind turbine gearbox is in low-frequency vibration region, lower hydraulic mount is flowed between upper and lower chamber by the liquid in it, and low-frequency vibration energy is dissipated as early as possible, thus realizes the object of wind turbine gearbox being carried out to vibration damping in the vibration of low frequency region.
When wind turbine gearbox is in medium-high frequency vibration area, the liquid in lower hydraulic mount circulates hardly, this at present hydraulic mount accelerated 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 lower hydraulic mounts through overtesting, thus the liquid in the chamber of the first tuning pipeline and second tune pipeline communication two lower hydraulic mounts can be passed through, a part of dither in two lower hydraulic mount chambers is cancelled out each other, thus effective raising carry out vibration damping and isolation effect to the vibration of wind turbine gearbox in medium-high frequency region.
Further, because the vibration of the bottom chamber of lower hydraulic mount is through overdamping, thus with the upper chamber of hydraulic mount is different with the vibration frequency of bottom chamber, there is certain otherness once; And the Single port of first of this programme the tuning pipeline is connected with the upper chamber of once hydraulic mount, another port is connected with the lower chambers of another lower hydraulic mount (namely descend the lower chambers of the upper chamber of hydraulic mount and another time hydraulic mount to communicate); The Single port of second tune pipeline is connected with the lower chambers of once hydraulic mount, and another port is connected with the upper chamber of another lower hydraulic mount (namely descend the lower chambers of the upper chamber of hydraulic mount and another time hydraulic mount to communicate); The otherness of upper chamber and bottom chamber vibration frequency can be utilized like this, the vibration in two lower hydraulic mount chambers is effectively avoided to superpose, dither in further increase twice hydraulic mount chambers is cancelled out each other part, improves the effectiveness in vibration suppression of wind turbine gearbox in medium-high frequency region further.
On the other hand, although the chamber in the first tuning pipeline and second tune pipeline communication two lower hydraulic mounts is conducive to improving the effectiveness in vibration suppression of wind turbine gearbox in medium-high frequency region, but when low frequency, large amplitude excitation, likely produce the superposition of twice hydraulic mount chambers internal vibration, and affect the normal use of vibration damping scaffold.Such as, in low-frequency vibration process, the chamber of a lower hydraulic mount is in confined state, when the chamber of another lower hydraulic mount is in and is stretched state, just easily vibrates superposition in the chamber of these twice hydraulic mounts.Thus, in order to avoid when low frequency, large amplitude excitation, produce the superposition of twice hydraulic mount chambers internal vibration, 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 lower hydraulic mount in two the lower hydraulic mounts be interconnected is in confined state, when the chamber of another lower hydraulic mount is in and is stretched state, due to low frequency, liquid stream momentum in the large amplitude process of motivation in lower hydraulic mount is large, thus liquid in the chamber of the lower hydraulic mount of confined state is in by toward the chamber indoor moveable of lower 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 twice hydraulic mount chambers internal vibration, 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 lower hydraulic mount circulates hardly, thus there is not this problem.
As preferably, lower hydraulic mount also comprises the upper reaches guidance tape, decoupling zero sheet, dirty guidance tape and the leather cup that distribute successively from top to bottom, and described upper chamber is positioned at above the guidance tape of upper reaches, and lower chambers is between dirty guidance tape and leather cup; Described first tuning pipeline comprises the first vertical long pipeline, first connecting tube of the first vertical short duct and connection the first vertical long pipeline lower end and the first vertical short duct lower end, the upper end-hole of the described first vertical long pipeline passes the leather cup of hydraulic mount, dirty guidance tape, decoupling zero sheet and upper reaches guidance tape from bottom to top, and is communicated with the upper chamber of this lower hydraulic mount; The upper end-hole of the described first vertical short duct from bottom to top through the leather cup of hydraulic mount under another, and is communicated with the lower chambers of this lower hydraulic mount; Described second tune pipeline comprises the second vertical long pipeline, second connecting tube of the second vertical short duct and connection the second vertical long pipeline lower end and the second vertical short duct lower end, described second vertical long pipeline is plugged in the first vertical short duct, the upper end-hole of the second vertical long pipeline from bottom to top through the leather cup of lower hydraulic mount, dirty guidance tape, decoupling zero sheet and upper reaches guidance tape, and is communicated with the upper chamber of this lower hydraulic mount; Described second vertical short duct is set on the first vertical long pipeline, and the upper end-hole of the second vertical short duct from bottom to top through the leather cup of hydraulic mount under another, and is communicated with the lower chambers of this lower hydraulic mount.
