Compared with prior art, the present invention has following substantive distinguishing features outstanding:
(1) disclosed in the CN201510617860.4 compared with technology, the present invention has following substantive distinguishing features outstanding:
1) used method is worn from prediction to be compared:
In the tunneling process of rock tunnel development machine, hobboing cutter is contacted under cutterhead thrust and torque collective effect and is rolled simultaneously
Cutting removing rock, cutter and rock constitute the mechanical system for being in contact with each other, interacting.Hob abrasion is hobboing cutter cutter ring table
Plane materiel material and rock mass surfacing persistently contact with each other effect as a result, with contact material, contact form, contact load and connecing
It touches the variations of factors such as operating condition and changes.Hob abrasion develop inherent law be predict hob abrasion evolutionary process basis with
It is crucial.
CN201510617860.4 passes through boring parameter variation caused by being changed to abrasion front and back by hobboing cutter geometric radius
Comparative analysis, the method for proposing prediction rock tunnel(ling) machine hob abrasion degree do not develop this essential mistake to hob abrasion
Cheng Jinhang gos deep into systematic research, it is difficult to estimate the pilot process of hob abrasion evolution.CN201510617860.4 considers rolling
The variation of knife geometric radius changes this interrelated factor with rock tunnel(ling) machine boring parameter, by the variation for analyzing boring parameter

2) comparison of parameter used in two methods:
Abrasion is that two solid surface materials persistently contact with each other the result of effect.Contact material feature, contact load with
Contact operating condition is the key factor for influencing abrasion and developing.During Specific construction, rock tunnel development machine hobboing cutter material is basic
It is consistent.Rock mass constantly changes with the difference of geological conditions, and the erosion property of rock directly affects hob abrasion.And
And ROCK MASS JOINT structure and knife disc tool arrangement of features will affect hobboing cutter stress, and then influence the wear process of hobboing cutter.
CN201510617860.4 predicts hob abrasion by boring parameter correlation before and after analysis hob abrasion, ignores
Rock mass materials and influence of the joint structure to hob abrasion.CN201510617860.4 is pre- using the correlation of boring parameter

The real-time detection of journey.
(2) disclosed in the CN201610771253.8 compared with technology, the present invention has following substantive distinguishing features outstanding:
1) it is analyzed and is compared from the angle that used load parameter is worn in prediction:
Abrasion is that two surfaces of solids contact with each other effect as a result, contact stress is the key mechanics ginseng for influencing wear process
Amount.In hobboing cutter rock break-off process, it is face contact that hobboing cutter is contacted with rock mass, and contact stress can directly reflect each infinitesimal in contact area
The stress condition of upper material.
CN201610771253.8 is with disk cutter normal thrust loading prediction tool wear, it is difficult to which true reflection hobboing cutter is broken
The stress condition on infinitesimal is contacted when rock.By CN201610771253.8 invention disclosed content and embodiment as it can be seen that this is existing
Technology considers this influence factor of load, it is intended to predict cutter by disk cutter normal thrust load and mechanical parameters
Wear process, but the disadvantage present in it is: disk cutter normal thrust load is difficult to reflect strictly according to the facts in contact area often
Material load on a infinitesimal, and then affect the accuracy of prediction result.
The present invention fully takes into account the shadow of contact stress Cutter wear process during establishing real-time detection method
It rings, using contact stress as the key mechanics parameter of prediction tool wear, and analyzes rock mass structure parameter comprehensively (i.e. for the first time
Joint strike inclination angle and joint spacing) influence to contact stress, mention computation model more close to the practical rock break-off process of hobboing cutter,
The high accuracy of real-time detection result.
2) comparison of mechanical analysis used by two methods:
Rock material is special fragile material, and destructive process is complicated, not there is only flexible deformation, plastic deformation, is also damaged
Hurt failure procedure.Meanwhile the stress of ROCK MASS JOINT feature and knife disc tool arrangement of features when can be to hobboing cutter broken rock generates shadow
It rings.
By CN201610771253.8 invention disclosed content and embodiment as it can be seen that the prior art merely with material bullet
Property modulus and Poisson's ratio, assumed (specified) load, it is intended to which actual load characteristic is reflected by elastic mechanics model.But present in it
Disadvantage is: single analysis on elasticity can not embody damage of rock failure procedure.So from analysis hobboing cutter broken rock mechanics
From the point of view of process, there are biggish calculating errors during LOAD FOR for the patented technology.
The present invention fully takes into account the special destructive process of rock and rock mass section during hobboing cutter broken rock mechanical analysis
The influence for managing structure feature and knife disc tool arrangement of features starts with from analysis rock mass bearing capacity, innovatively proposes consideration

The frictional property of contact surface directly affects the size that slip region in region is in rolling contact under tractive force effect.?
Cutter material property is basically unchanged in hard rock tunnel development machine practice of construction, and the rock mass characteristics for tunneling geology constantly convert.Therefore,
In hobboing cutter rock break-off process, the sliding distance in the movement of hobboing cutter skid is codetermined by hobboing cutter load and rock frictional test property.
CN201710910463.5 calculates hobboing cutter skid fortune with the relative value of the disk cutter horizontal force being subject to and normal force
Dynamic sliding distance has ignored the influence of rock contact suface friction confrontation sliding distance.By CN201710910463.5 public affairs
The summary of the invention and embodiment opened are as it can be seen that the prior art considers this influence factor of load, it is intended to be cut by disk cutter
Cut the sliding distance in coefficient calculating hobboing cutter skid movement, but the disadvantage present in it is: disk cutter cutting coefficient is difficult
To reflect relative motion situation of the contact surface on each infinitesimal comprehensively, and then affect the accuracy of prediction result.
The present invention fully takes into account load and contact surface frictional property to rolling during establishing real-time detection method
The influence of knife skid movement is innovatively proposed using cutting coefficient and rock frictional test coefficient as calculating hobboing cutter sliding distance
Key parameter, so that computation model more close to hobboing cutter and the practical rolling-sliding contact process of rock mass, is improved real-time detection result
Accuracy.
