reflects the closeness of structural blocks (struc- tural elements) among themselves in the structural model of the mechatronic module. It is determined from the dependence [9]: where r ij is the element of the distance matrix R , equal to the length of the shortest path (the number of minimal links - arrows ) from block i to block j . If there is no such path, then the corresponding matrix element is assumed to be infinite. In order for the result of the calculations with the given formula to be definite, the elements r ij of the matrix R , equal to infinity, are assigned finite values equal to the number of blocks of the structure model. The maximum structural compactness will have structures in which there are reciprocal and reverse links between all blocks of the structural model (Fig. 3.9) Figure 3.9 Structural compactness indirectly characterizes the simplicity of the organization of connections between individual blocks of the structural model. 203 When designing, the designer should strive to increase the structural compactness. Let us determine the structural compactness for various types of mecha- tronic modules. For the motion module (see Figure 3.5): distance matrix We replace infinity by the number of blocks in the structural model n = 2 and obtain a transformed distance matrix: Structural compactness: For the mechatronic modulus of motion (see Fig. 3.6): distance matrix structural compactness For an intelligent mechatronic module (see Figure 3.7): distance matrix Structural compactness 204 For the integrated intelligent mechatronic module (see Figure 3.8): distance matrix structural compactness For an integrated intelligent mechatronic module containing four structural elements, the structural compactness is 0.75 Thus, with the growth of structural integration, the structural compactness of the intellectual mechatronic modul changes. жүктеу/скачать 11,25 Mb.
