Example two
Referring to fig. 3, a flowchart of a model generation method in the second embodiment of the present invention is shown, which specifically may include:
in step 201, component information of a plurality of components is obtained.
In the embodiment of the present invention, the specific implementation manner of this step may refer to the description in the foregoing embodiment, and details are not described herein.
And step 202, respectively establishing discrete points on each part according to the specification information and the grid number.
In the embodiment of the present invention, the part information includes specification information and the number of meshes. The specification information includes, but is not limited to, length, width, depth, diameter, etc., or any other suitable specification information, which is not limited in this respect by embodiments of the present invention. The number of grids refers to the number of grids to be built in various directions when a grid model is built, and the number of grids can be manually set or can be determined according to specification and size. Discrete points are the vertices of the mesh in the mesh model. According to the specification information and the number of meshes, the finite element automated modeling tool can automatically establish discrete points on the component.
For example, the diameter D of the arm, the length L of the arm, the number n of meshes in the axial direction of the arm, and the number m of meshes in the circumferential direction of the arm. And (3) establishing a grid model of the arm rod, and if the left-end coordinates of the arm rod are (0, 0) and the right-end coordinates of the arm rod are (L, 0), dividing the nodes of the dispersed grid into L/(n) +1 sections in the axial direction and dividing the nodes into (360/m) nodes in the circumferential direction. The first coordinates of the first section are (0, D/2, 0), the second coordinates are (0, D/2 × (cos (1 × 360/m)), D/2 × (sin (1 × 360/m))), the third coordinates are (0, D/2 × (cos (2 × 360/m)), D/2 × (sin (2 × 360/m))), and so on, and the 360/(m) th points are (0, D/2 × (cos ((m-1) × 360/m))), D/2 × (sin ((m-1) × 360/m))). The first point of the second section has coordinates of (L/n, D/2, 0), the second point has coordinates of (L/n, D/2 × (cos (1 × 360/m)), D/2 × (sin (1 × 360/m))), the third point has coordinates of (L/n, D/2 × (cos (2 × 360/m)) D/2 × (sin (2 × 360/m)), and so on, and the 360/(m) th point has coordinates of (L/n, D/2 × (cos ((m-1) × 360/m)), D/2 × (sin ((m-1) × 360/m)). By analogy, the first point of the L/(n) +1 section has coordinates of (L, D/2, 0), the second point has coordinates of (L, D/2 x (cos (1 × 360/m)), D/2 x (sin (1 × 360/m)), the third point has coordinates of (L, D/2 x (cos (2 × 360/m)), D/2 x (sin (2 × 360/m)), and so on, and the 360/(m) th point has coordinates of (L, D/2 x (cos ((m-1) × 360/m)), D/2 x (sin ((m-1) × 360/m)), and so on, all the discrete points on the entire arm are established.
And 203, respectively connecting the discrete points on each part into a quadrilateral grid to obtain the part model data.
In the embodiment of the invention, after the discrete points on the part are established, the discrete points are connected into the quadrilateral grids to generate the grid model, and the part model data is obtained. For example, all discrete points on the whole arm are completely established, two adjacent points on the first cross section and two adjacent points on the adjacent cross section in the same sequence are sequentially selected to be connected into a quadrangle according to the cross section sequence and the creation sequence of each cross section point, and then the creation of the grid model of the arm is completed, and the part model data of the arm is obtained.
And 204, respectively establishing a coordinate system of a target end point at the connecting position between the two parts on the first part and the second part according to the specification information to obtain coordinate system data.
In an embodiment of the invention, the parts comprise a first part and a second part, and in order to assemble the first part and the second part together, a coordinate system of the end point position of the connection between the two parts on the first part and the second part needs to be established to obtain coordinate system data of the end point position of the first part and coordinate system data of the end point position of the second part.
For example, for the arm, a coordinate system of the arm is created according to the diameter D and the length L of the arm, the origin of the coordinate system of the left end of the arm is (0, 0), the direction vector of the X direction is (L, 0), the direction vector of the Y direction is (0, D/2, 0), and the transformation matrix of the coordinate system is TA1. The origin of the coordinate system at the right end of the arm rod is (L, 0), the direction vector in the X direction is (0, 0), the direction vector in the Y direction is (L, D/2, 0), and the conversion matrix of the coordinate system is TB1. As shown in fig. 4, for a schematic diagram of a modeling interface of a joint, a central coordinate of the joint, a coordinate system origin of a joint a end, an included angle between a coordinate system Z axis of a point a and a global X axis, an included angle between the Z axis and a global Y axis, an X-direction vector of the point a, a coordinate system origin of a joint B end, an included angle between the coordinate system Z axis of a point B and a global X axis, an included angle between the Z axis and a global Y axis, and an X-direction vector of the point B are obtained, and according to the above conditions, the coordinate origin of the joint, the coordinate system of the joint a end, a coordinate matrix of which is AT, and the coordinate system of the joint B end, a coordinate matrix of which is BT are calculated.
In the embodiment of the invention, when the assembly relationship between the first component and the second component is established, the component model data of the first component and the second component are added firstly. Of course, a third member, a fourth member, and the like may be included in addition to the first member and the second member, and the embodiment of the present invention is explained taking the assembly between the first member and the second member as an example.
For example, the joint is introduced first, assuming that the position of the first component introduced is the default position. Then, the arm is introduced, and at this time, the part model data of the joint and the part model data of the arm are independent of each other.
And step 206, controlling the first component or the second component to move according to the coordinate system data of the first component and the second component, so that the coordinate system of the target end point of the first component is coincident with the coordinate system of the target end point of the second component.
In the embodiment of the invention, the first part or the second part is controlled to move according to the coordinate system data of the first part and the second part, so that after the first part moves or the second part moves, the coordinate system of the target end point of the first part and the coordinate system of the target end point of the second part can be superposed.
For example, as shown in the assembly diagram of the satellite antenna shown in FIG. 5, the left side of the arm (first member) is manually designatedThe coordinate system of the end is coincident with the coordinate system of the B end of the joint (second component), and then the coordinate transformation relation of all nodes on the arm rod is T1 -1 Multiplying the multiplied BT by the coordinate of a certain point on the arm lever, and circularly traversing all the points in the arm lever to obtain the position of the transformed arm lever. If another joint is provided and another joint is introduced, the transformation relation of the joint is AT1 under the condition that the A end of the joint is coincident with the right end of the arm rod -1 ×T1 -1 And (6) BT (x). The transformed position of the arm or joint is determined therefrom, and the arm or joint is controlled to move to that position to complete the assembly of the arm and joint, thereby obtaining an assembled device.
And step 207, exporting the component model data of the first component and the second component, the coordinate system data of the first component and the second component after movement, and the coordinate coefficient data of the assembled equipment model as the assembled equipment model.
In the embodiment of the invention, after the first component or the second component is moved, the coordinate system data of the first component and the coordinate system data of the second component are obtained. And then, the coordinate system data of the whole equipment model can be calculated according to the coordinate system data of the first component and the second component. For example, the fitting relationship between a plurality of arms and a plurality of joints is determined in order, and the inverse matrix of the coordinate system matrix is continuously pre-multiplied by the transformation relationship to obtain the global coordinates of the entire fitting as the coordinate system data of the entire device model.
In an embodiment of the present invention, the part model data of the part, the coordinate system data of the moved part, and the coordinate coefficient data of the assembled equipment model are derived as the assembled equipment model. For example, the spatial position and unit format of the whole assembled satellite antenna model are derived for the identification and calling of the general CAE software.
According to the embodiment of the invention, the part information of a plurality of parts is obtained, the discrete points on each part are respectively established according to the specification information and the grid number, the discrete points on each part are respectively connected into the quadrilateral grids to obtain the part model data, the coordinate system of the target end point at the connection part between the two parts on the first part and the second part is respectively established according to the specification information to obtain the coordinate system data, the part model data of the first part and the second part are added, the first part or the second part is controlled to move according to the coordinate system data of the first part and the second part, so that the coordinate system of the target end point of the first part is superposed with the coordinate system of the target end point of the second part, the part model data of the first part and the second part, the coordinate system data of the first part and the second part after moving and the coordinate coefficient data of the assembled equipment model are exported as the assembled equipment model, the plurality of parts of the equipment are respectively modeled, the coordinate system model data of the first part and the second part after moving are combined together, the problem of calculating the position of the equipment by manual calculation is solved, and the problem of the calculation of the equipment is reduced.
