Specific embodiment
Further to illustrate the present invention to reach technological means and effect that predetermined goal of the invention is taken, Below in conjunction with accompanying drawing and preferred embodiment, it is as follows that the present invention is described in detail.
Any point when measurement apparatus of movement locus of object provided by the present invention can be moved with Measuring Object Movement locus, be mainly used in the measurement of space object athletic posture or spatial point movement locus, it is main suitable For automobile power assembly, front-rear axle etc., these scopes are also not limited to, for example, apply also for excavator The movement locus measurement of bucket.The structure of the measurement apparatus of the movement locus of object that Fig. 1 is provided for the present invention Schematic diagram, structured flowcharts of the Fig. 2 for the measurement apparatus of Fig. 1, as shown in Figures 1 and 2, the present invention is carried For measurement apparatus 100 include base plate 110, stay-supported type displacement sensor 120 and data processor 130, The quantity of stay-supported type displacement sensor 120 is three, 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 displacements Sensor 120 is both secured on base plate 110, wherein the first stay-supported type displacement sensor 121 is fixed on bottom At A points position on plate 110, the second stay-supported type displacement sensor 122 is fixed on the B on base plate 110 At point position, the 3rd stay-supported type displacement sensor 123 is fixed at the points of the C on base plate 110 position.Often One stay-supported type displacement sensor 120 is provided with bracing wire 124, and each bracing wire 124 is from corresponding stay-supported Pull out in displacement transducer 120.The movement locus of certain point on object are being carried out using the measurement apparatus During measurement, each bracing wire 124 is both secured to object under test away from one end of stay-supported type displacement sensor 120 Same point on and each bracing wire 124 be in tension, each stay-supported type displacement sensor 120 For measuring tensile elongation of the bracing wire 124 being connected with the stay-supported type displacement sensor 120 at each moment, And by tensile elongation data transfer to data processor 130,130 pairs of three stay-supported positions of data processor The tensile elongation data of the feedback of displacement sensor 120 carry out integrated treatment and calculate so as to obtain on object under test Measurement point in the space coordinatess at each moment, and then obtain the movement locus of the measurement point.
Fig. 3 is schematic diagram of the measurement apparatus of Fig. 1 when the movement locus of tested point are measured, such as Fig. 3 institutes Show, when the movement locus of tested point (D points as shown in Figure 3) are measured, by each stay-supported position The bracing wire 124 of displacement sensor 120 is all secured on tested point D (i.e. three stay-supported type displacement sensors 120 Fixing point A, B, C constitute a triangle, three fixing points A, B, C and tested point D composition One triangular pyramid), and the distance between each fixing point of three stay-supported type displacement sensors 120 is measured, That is the distance between 2 points of AC, BC and AB is respectively a1, a2And a3
Then the plane being located using three fixing points A, B, C sets up space right-angle as XY coordinate planes Coordinate system, for the ease of calculating, the fixing point (i.e. A points) with the first stay-supported type displacement sensor 121 For origin, and make the fixing point (i.e. A points) and the second stay-supported of the first stay-supported type displacement sensor 121 The line of the fixing point (i.e. B points) of displacement transducer 122 is located on Y-axis, and the 3rd stay-supported position In XY coordinate planes, now the coordinate of A points is the fixing point (i.e. C points) of displacement sensor 123 (0,0,0), the coordinate of B points is (0, a3, 0).
By length a on each side of AC, BC and AB in the triangle of 3 points of compositions of ABC1、a2、a3And The coordinate that 2 point of A, B (0,0,0), (0, a3, 0), you can draw C points coordinate (h, m, 0), Its computing formula is:
Wherein:Abscissa and vertical coordinate of the h and m for C points;
a1, a2And a3Respectively the distance between 2 points of AC, BC and AB.
According to the tensile elongation numerical value of bracing wire 124 on three stay-supported type displacement sensors 120, take with for the moment The tensile elongation of bracing wire 124 on the first stay-supported type displacement sensor 121 is carved (i.e. between 2 points of AD Distance) for l1, tensile elongation (the i.e. BD two of bracing wire 124 on the second stay-supported type displacement sensor 122 The distance between point) for l3, on the 3rd stay-supported type displacement sensor 123, the tensile elongation of bracing wire 124 is (i.e. The distance between 2 points of CD) for l2, it is assumed that moment D point coordinate be (x, y, z).Then basis Computing formula:
x2+y2+z2=l1 2
(x-h)2+(y-m)2+z2=l2 2
x2+(y-a3)2+z2=l3 2
Coordinate of the D points at the moment is obtained, i.e.,:
Wherein, x, y, z are respectively the abscissa of D points, vertical coordinate and ordinate;
H and m is respectively the abscissa and vertical coordinate of C points;
l1, l2And l3Distance respectively between 2 points of synchronization AD, CD and BD.
D points coordinate (x, y, z) at a time is obtained by above-mentioned calculating, by determining D The coordinate of point is can determine that in the position of moment D point, for the D points of continuous motion, if being then obtained The coordinate of each moment D point is connected into a curve by a dry coordinate, you can learn that D points (namely are treated Measuring point) movement locus.
In order to more easily calculate the coordinate of D points, it is preferable that the trianglees of 3 points of ABC composition can be with For equilateral triangle or isosceles right triangle.
When the triangle of 3 points of compositions of ABC is equilateral triangle (i.e. a1=a2=a3=a) when, now:
It may thus be appreciated that the coordinate of D points is:
Wherein:l1, l2And l3Distance respectively between 2 points of synchronization AD, CD and BD;
A is the distance between 2 points of AC, BC and AB.
When the trianglees of 3 points of ABC composition are isosceles right triangle, i.e. the coordinate of B points for (0, a, 0), the coordinate of C points for (a, 0, when 0), now:
H=a
M=0
It may thus be appreciated that the coordinate of D points is:
Wherein:l1, l2And l3Distance respectively between 2 points of synchronization AD, CD and BD;
A is the distance between 2 points of AB and AC.
