The present invention is further illustrated below by embodiment:
Embodiment one, the concrete performing step of the present invention is as follows:
Step 1: on analyzing adapter groove type and size basis, sets up two-sided bilateral u shaped connector parameter model, as shown in Figure 2,
for the bilateral coefficient of groove list,
for bilateral groove,
for bevel, if upper groove is the first face of weld, lower groove is the rear face of weld,
for the groove depth of the rear face of weld,
expression groove is one side,
for whole groove thickness,
be respectively upper and lower groove angle,
for climb and fall port radius,
for the width of root face,
for group is to gap.Some common single, double surfaces, symmetrical groove type can develop with bilateral bevel shape Parameters variation, Fig. 2 is for represent on basis at the U-shaped groove of bilateral double-sided symmetrical, develop into the U-shaped groove of bilateral one side when Parameters variation, other type bevel shape is also obtained by Parameters variation;
Step 2; In order to simplify cross-sectional area calculating, weld area is resolved into four parts, by dotted portion mark, as shown in Figure 3, groove cross-sectional area
, clearance cross section area
, weld reinforcement cross-sectional area
, back chipping weld area
, overall cross-section
; When groove is two-sided,
;
;
; Wherein
be made up of fan-shaped, trapezoidal and an Atria basic geometric figure.The object of decomposing calculates global sections area by calculating four local unit areas.Clearance cross section area
; Back chipping cross section adopts approximate treatment equally
,
,
be respectively back chipping width and back chipping height.Key is
calculating, it is comparatively large, more difficult that it fills on groove the computational accuracy impact that wlding consumes;
Step 3: bilateral two-sided U-shaped section of weld joint areal calculation expression formula of deriving.From the bevel design angle of specification, deposit in case at root radius, groove ascender line should be tangent with circular arc, and tangency location is relevant with groove angle α, and as T point in Fig. 4, calculating layer groove section is by layer height
carry out, layer height is for benchmark with the upper end horizontal line of groove.Obvious area of section calculates should consider arc section and straight-line segment, and its separation is T point.T point is the critical value of segmentation calculating to groove upper end horizon distance
, can be obtained by geometry relation
, when
time, need to calculate weld reinforcement area of section.The area of section computation model designed according to layer thickness as shown in Figure 4, Figure 5.Three kinds of situations are divided to amass computation model to discuss the bilateral U-shaped groove section of one side below:
3.1: layer is high
: as shown in Figure 4,
for hatched area in figure, its value is circular arc area
with triangle area
difference.Central angle
,
,
;
3.2: layer is high
: as shown in Figure 5,
be hatched area in figure
with trapezoidal area
sum,
for sectorial area
with triangle area
difference, wherein
,
, trapezoidal
upper base
, go to the bottom
, high
, then
;
3.3: layer is high
: need to calculate reinforcement area of section, because groove reinforcement is less than reinforcement arc radius, bow-shaped cross-section area adopts approximate formula, and whole arcuate base length is
;
Comprehensively above-mentioned three kinds of situations, calculate based on layer thickness through analytic derivation
the bilateral U-shaped groove section areal calculation of whole one side as follows:
when
time, one side is bilateral
it is bilateral that type groove deteriorates to one side
type groove, is applicable to the second situation, now,
.
, this demonstrates the unitarity of model from another point of view.The reference area that formula (3) is reinforcement.Rear face of weld area of section result of calculation is as shown in formula (4), (5), (6);

, rear weldering portion cross-sectional area
, then whole weld seam area
.For welding by one side
.
,
for some layers of operation cross-sectional area sum.
If the first face of weld has
individual layer, the
the throat depth of layer welding sequence is
, cross-sectional area is
,
for from benchmark to
layer total cross-sectional area, benchmark is selected in the bottom of groove,
for from benchmark to
the thickness of layer,
for the total area of the first face of weld; The rear face of weld has
individual layer, the
the throat depth of layer welding sequence is
, cross-sectional area is
,
for from benchmark to
layer total cross-sectional area,
for from benchmark to
the thickness of layer,
for the total area of the rear face of weld.
For the first face of weld of the U-shaped groove of double-sided symmetrical, calculate layer area of section
it is the target that model is set up.Its thought solved first calculates from ground floor to
the whole area of section of layer
, before then deducting
the layer cross section total area
, namely
, to
layer cross section areal calculation, needs the history utilizing back to calculate data
