Accompanying drawing explanation
Fig. 1 is the schematic diagram of the slide contact member according to band solid lubricant coating of the present invention.
Embodiment
The slide contact member (to part) 1 and 2 of the band solid lubricant coating of non-coordinating contact has each other been shown in Fig. 1, and the two makes relative sliding.Slide contact member 1 has matrix S1 and is formed in the solid lubricant coating C1 on this matrix, and slide contact member 2 has matrix S2 and is formed in the solid lubricant coating C2 on this matrix.
But, only can there is one in slide contact member 1 and 2 and only have solid lubricant coating.
The material of matrix S1 has elastic modulus E
1swith Poisson ratio v
1s, the material of matrix S2 has elastic modulus E
2swith Poisson ratio v
2s.
Solid lubricant coating C1 has outer surface curvature radius R1 and thickness h 1, and elasticity modulus of materials E
1cwith Poisson ratio v
1c; Solid lubricant coating C2 has outer surface curvature radius R2 and thickness h 2, and elasticity modulus of materials E
2cwith Poisson ratio v
2c.The material of described solid lubricant coating is bonded solid lubricant coating, diamond-like coating, metallic coating, or metallic composite coating etc.
The actual external surface b that solid lubricant coating C1, C2 have nominal outside surface a separately and cause because of surfaceness.
Outer surface curvature radius R1, R2 of slide contact member 1 and 2 can be on the occasion of, namely outside surface has convex shape shown in figure.One of radius of curvature R 1, R2 can be also negative value or infinity, as long as guarantee between slide contact member 1 and 2 for non-coordinating contacts.
Such as, this method is applicable to the non-coordinating contact of any possibility form between convex outward (outer convex spherical, evagination cylinder etc.), inner sunken face (interior concave spherical surface, indent cylinder etc.), plane etc.
Between convex outward with inner sunken face, non-coordinating contacts, the absolute value of the radius-of-curvature of the two must have larger difference.Such as, in axis hole contact, the cross sectional dimensions of axle is more much smaller than hole; In ball-and-socket contact, the size of ball is more much smaller than the size of nest.
A preferred embodiment of the present invention is the contact between sphere.The present invention is equally applicable to aspheric surfaces contact, as flat pressure head (area is less) and the Contact being with the slide contact member of solid lubricant coating (area is comparatively large, plane or convex outward).
In addition, each slide contact member outside surface can not only have single radius-of-curvature, but can also have the combination between multiple radius-of-curvature.
At work, slide contact member 1 and 2 relative sliding, slide contact member 1 is to slide contact member 2 imposed load L simultaneously, forms contact thus between slide contact member 1 and 2.
According to the present invention, in the manufacture method of the slide contact member of band solid lubricant coating, need the outline (comprising the information such as coating thickness, geometric configuration) accurately determining required solid lubricant coating; And in order to determine the outline of solid lubricant coating, first the wear extent of solid lubricant coating to be calculated by slide contact member solid lubricant coating wear extent defining method according to the present invention.
The wear extent defining method of corresponding solid lubricant coating in slide contact member 1 and 2 relative sliding process is described below.
First, total sliding time T can be divided into Q tiny time section dt, at [t

q(i, j) is by Archard formulae discovery:
In formula, the force value at p (i, j) representation node (i, j) place, u is the speed of related movement of contact.K is the coefficient of waste.For trying to achieve p (i, j), the contact problems of stratified material are described as:

P (i, j) >=0, g (i, j) >=0 and p (i, j) g (i, j)=0, i=1,2 ..., M, j=1,2 ..., N (5)
In formula, g (i, j) represents normal gap between surface of contact, is expressed as:
In formula,
the geometrical interference at point (i, j) place, h
0(i, j) is the primary clearance at point (i, j) place, δ

In formula,
be the time-domain expression of pressure-Normal Displacement influence coefficient, in coating material contact calculates, calculate with its frequency-domain expression and obtain
[3]:
(8)
Following system of equations can be listed after influence coefficient solves and obtains:
ΔxΔy∑p(i，j)＝W (11)
Formula (9,10) is the complementary equation of Kuhn-Tucker, and formula (11) is counterweight balance equation, and W is normal load.Then, solve with CGM, contact p (i, j) can be obtained.Wherein, inequality constrain is forced to meet in computation process, contact region and counterweight balance adjust in iteration is crossed, idiographic flow can list of references [4] (Polonsky I A and Keer L M.A numerical method forsolving rough contact problems based on the multi-level multi-summationand conjugate gradient techniques.Wear, 1999, Vol.231, p.206-219).
After obtaining the wear volume in the dt of each interval, relative sliding from slide contact member is until t
qmoment (t
q=q*dt, q=1,2 ... Q) total wear volume be:
Correspondingly, the wear profile in each moment also by removing the wear volume V of accumulation from cumulative volume
qtry to achieve.
In the process of the wear extent of above-mentioned calculating solid lubricant coating, need the contact used between slide contact member.
