Embodiment
For further setting forth the utility model for the technological means reaching predetermined utility model object and take and effect, below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in detail as follows.
The movement locus of any point when the measurement mechanism of movement locus of object provided by the utility model can measure object of which movement, be mainly used in the measurement of space object athletic posture or spatial point movement locus, mainly be applicable to automobile power assembly, front-rear axle etc., also be not limited to these scopes, the movement locus being such as also applicable to excavator-type shovel clamshell excavator is measured.The structural representation of the measurement mechanism of the movement locus of object that Fig. 1 provides for the utility model, Fig. 2 is the structured flowchart of the measurement mechanism of Fig. 1, as shown in Figures 1 and 2, the measurement mechanism 100 that the utility model provides comprises base plate 110, stay-supported type displacement sensor 120 and data processor 130, the quantity of stay-supported type displacement sensor 120 is three, be respectively the first stay-supported type displacement sensor 121, second stay-supported type displacement sensor 122 and the 3rd stay-supported type displacement sensor 123, three stay-supported type displacement sensors 120 are all fixed on base plate 110, wherein the first stay-supported type displacement sensor 121 is fixed on the A point position on base plate 110, second stay-supported type displacement sensor 122 is fixed on the B point position on base plate 110, 3rd stay-supported type displacement sensor 123 is fixed on the C point position on base plate 110.Each stay-supported type displacement sensor 120 is provided with bracing wire 124, and each bracing wire 124 pulls out from the stay-supported type displacement sensor 120 of correspondence.Utilizing this measurement mechanism to when certain any movement locus is measured on object, each bracing wire 124 to be all fixed in the same point of object under test away from one end of stay-supported type displacement sensor 120 and each bracing wire 124 is in tension, each stay-supported type displacement sensor 120 is for measuring the bracing wire 124 that is connected with this stay-supported type displacement sensor 120 tensile elongation in each moment, and tensile elongation data are passed to data processor 130, data processor 130 carries out overall treatment and calculating to the tensile elongation data that three stay-supported type displacement sensors 120 feed back thus obtains the volume coordinate of the measurement point on object under test in each moment, and then obtain the movement locus of this measurement point.
Fig. 3 is the schematic diagram of measurement mechanism when measuring the movement locus of tested point of Fig. 1, as shown in Figure 3, when measuring the movement locus of tested point (D point as shown in Figure 3), the bracing wire 124 of each stay-supported type displacement sensor 120 is all fixed to (the i.e. point of fixity A of three stay-supported type displacement sensors 120 on tested point D, B, C forms a triangle, three point of fixity A, B, C and tested point D forms a triangular pyramid), and the distance between each point of fixity measuring three stay-supported type displacement sensors 120, i.e. AC, distance between BC and AB 2 is respectively a 1, a 2and a 3.
Then with three point of fixity A, B, the plane at C place sets up rectangular coordinate system in space as XY coordinate plane, for the ease of calculating, with the point of fixity of the first stay-supported type displacement sensor 121 (i.e. A point) for initial point, and make the point of fixity of the first stay-supported type displacement sensor 121 (i.e. A point) be positioned on Y-axis with the line of the point of fixity (i.e. B point) of the second stay-supported type displacement sensor 122, and the point of fixity of the 3rd stay-supported type displacement sensor 123 (i.e. C point) is positioned at XY coordinate plane, now the coordinate of A point is (0, 0, 0), the coordinate of B point is (0, a 3, 0).
By the length a on each limit of AC, BC and AB in the triangle of ABC 3 composition 1, a 2, a 3and the coordinate of A, B 2 (0,0,0), (0, a 3, 0), can draw the coordinate (h, m, 0) of C point, its computing formula is:
h = a 1 2 - ( a 1 2 - a 2 2 + a 3 2 2 a 3 ) 2
m = a 1 2 - a 2 2 + a 3 2 2 a 3
Wherein: h and m is horizontal ordinate and the ordinate of C point;
A 1, a 2and a 3be respectively the distance between AC, BC and AB at 2.

x 2+y 2+z 2=l 1 2
(x-h) 2+(y-m) 2+z 2=l 2 2
x 2+(y-a 3) 2+z 2=l 3 2
Obtain the coordinate of D point in this moment, that is:

y = l 1 2 - l 3 2 + a 3 2 2 a 3
z = l 1 2 - ( l 1 2 - l 2 2 + m 2 + h 2 - 2 m l 1 2 - l 3 2 + a 3 2 2 a 3 2 h ) 2 - ( l 1 2 - l 3 2 + a 3 2 2 a 3 ) 2

When the triangle of ABC 3 composition is equilateral triangle (i.e. a 1=a 2=a 3=a) time, now:
h = 3 2 a
m = a 2
Therefore the coordinate of known D point is:
x = 1 2 l 1 2 - l 2 2 + 1 2 l 3 2 + 3 a 6
y = l 1 2 - l 3 2 + a 2 2 a
z = l 1 2 - ( l 1 2 - l 3 2 + a 2 2 a ) 2 - ( 1 2 l 1 2 - l 2 2 + 1 2 l 3 2 + 3 a 6 ) 2
Wherein: l 1, l 2and l 3be respectively the distance between synchronization AD, CD and BD at 2;
A is the distance between AC, BC and AB 2.
When the triangle of ABC 3 composition is isosceles right triangle, namely the coordinate of B point is (0, a, 0), when the coordinate of C point is (a, 0,0), now:
h=a
m=0
Therefore the coordinate of known D point is:
x = l 1 2 - l 3 2 + a 2 2 a
y = l 1 2 - l 2 2 + a 2 2 a
z = l 1 2 - ( l 1 2 - l 2 2 + a 2 ) 2 + ( l 1 2 - l 3 2 + a 2 ) 2 4 a 2
Wherein: l 1, l 2and l 3be respectively the distance between synchronization AD, CD and BD at 2;
A is the distance between AB and AC 2.
