Description
Technical field
The invention belongs to complete-section tunnel boring machine design fields, in existing traditional complete-section tunnel boring machine
On the basis of hobboing cutter-tool apron connection structure, a kind of TBM that the wedge-shaped block of material of part hobboing cutter connection is changed to damping alloy is devised
Cutterhead vibration damping scheme.
Background technique
In recent years, as economic rapid development and the progress of science and technology and the swift and violent growth of population result in soil
Resource it is increasingly poor, countries in the world gradually start to reinforce the exploitation to the underground space.Complete-section tunnel boring machine (TBM) conduct
The application of the high-end equipment of large size in constructing tunnel field is also more and more extensive.Currently, complete-section tunnel boring machine is widely used in
The fields such as water conservancy, electric power, railway, coal mine, traffic and city underground engineering.TBM is crushed in extremely complex geological environment
Rock, frequently absorbs impact load under long-term severe working condition, and cutterhead vibration is violent.TBM is strong during the work time
Vibration can seriously affect drivage efficiency, cause cutterhead gusset cracking, the failure of cutterhead tool apron weld cracking, main shaft seals etc. tight
The engineering problem of weight, increases the maintenance cost and construction period of machine.Hobboing cutter connects as complete-section tunnel boring machine and rock
The component of touching, directly participation rock break-off process subject the collective effect of space multipoint random load, and vibration is acutely and it is vibrated
Form passes to cutterhead through wedge block, tool apron, and connection structure is as shown in Figure 1.
Currently, having had already appeared two kinds of Basic Ways in mechanical vibration damping field: first is that designing and using vibration-proof structure；Second is that
Develop and use damping material.In the vibration damping field of complete-section tunnel boring machine, there are some scholars and enterprise both at home and abroad at present
Industry has carried out certain research, but they only consider vibration damping problem, and effectiveness in vibration suppression one from the mechanism for improving mechanical structure
As.Currently, the development of damp alloy material has been detached from laboratory and has been applied to production in fact in the field of material vibration damping
It tramples, has many advantages, such as features simple structure, small in size, lightweight, be widely used in the fields such as ship, aerospace, household electrical appliance.
Based on the above circumstances, the invention proposes part hobboing cutter is connected the TBM that wedge-shaped block of material is changed to damping alloy
Cutterhead vibration damping scheme.TBM cutterhead effectiveness in vibration suppression is obvious, reduces the damage vibrated to TBM other component, has been greatly reduced and has subtracted
Cost needed for vibration.
Summary of the invention
The present invention vibration problem strong based on solution complete-section tunnel boring machine cutterhead in tunneling process.In broken rock
In the process, interaction strong between rock and hobboing cutter is as vibration source, makes every effort to close to vibration damping at vibration source, to reduce vibration pair
The influence of other component.Now based on traditional hobboing cutter-tool apron connection structure, itself in-fighting can be passed through using damping alloy
The characteristics of vibration damping, achievees the purpose that vibration damping by the way that the wedge-shaped block of material of hobboing cutter connection is changed to damping alloy.In addition, due to resistance
Damping alloy is expensive, and hobboing cutter quantity is more on cutterhead, closes if all hobboing cutters are connected wedge-shaped block of material and are all changed to damping
Gold, cost are larger.Therefore, TBM cutterhead (such as Fig. 2) is divided into several regions by the present invention, and cutterhead is vibrated in intense regions
Hobboing cutter connects wedge-shaped block of material and is changed to damping alloy, reduces cost needed for vibration damping, and part hobboing cutter is connected wedge to realize
Shape block of material is changed to the purpose that damping alloy carrys out vibration damping.
Technical solution of the present invention:
Part hobboing cutter is connected wedge-shaped block of material and is changed to damping alloy by a kind of design method for TBM cutterhead vibration damping,

δ=1)；For cutter head structure coefficient, value range is 0.91~1.04, and cutterhead body piecemeal is more,It is worth bigger (this model
It takes)；R1、R2Be positive the diameter quotient in hobboing cutter region and side hobboing cutter region respectively, and value range is respectively 2.603~
3.535,0.346~1.705, circle diameter is bigger, and value is bigger；A is binomial coefficient, value range is 0.415~
0.487；B is index coefficient, and value range is 2.92~6.99；C is sinusoidal coefficients, value range is 3.209~
8.063；D is first phase coefficient, and value range is 3.224~3.649, what the above coefficient was divided with cutterhead in a circumferential direction
The reduction of unit angle value and increase；
Specification of a model:
(1) TBM cutterhead simplified model (such as Fig. 3) is first established, using cutter head center as the center of circle, respectively with central hob and cutterhead
Maximum distance, side hobboing cutter and the minimum range in the cutterhead center of circle in the center of circle are that radius does circle, and cutterhead is divided into radial directions
Three regions, from inside to outside respectively central hob region 3-1, positive hobboing cutter region 3-2 and side hobboing cutter region 3-3；
(2) using the horizontal line by cutter head center as first piece of thin plate, on the basis of first piece of thin plate, according to certain
Cutterhead is divided into several regions by angle value (this model is for 30 °) in a circumferential direction, in the direction of the clock from inside to outside
Successively write cutterhead region serial number x, x=1,2,3 ..., n；In positive hobboing cutter region 3-2, since left side, first will be located at
The serial number in the region above block thin plate is denoted as 1, after having write positive hobboing cutter region 3-2, writes side hobboing cutter area in the same way
Domain 3-3；
(3) it now brings the serial number that step (2) has been write into optimization of material model, solves f (x) value, if its value is non-whole
When number, round numbers part；Obtained value is just changed to damping alloy region to need to connect hobboing cutter into wedge-shaped block of material
Serial number (such as shadow region Fig. 3)；Until f (x) >=x stopping is brought into, obtained result is the region for all needing to replace.
Due to the complexity of TBM operating condition in tunneling process, this substitution model is not accurate calculated value, is had certain
Error, error can receive in engineering.
Beneficial effects of the present invention: for TBM in rock break-off process the strong vibration problem of cutterhead, the invention proposes materials
