GEOMETRICAL TRANSFORMATIONS OF ASSEMBLED UNITS

Аbstract

This paper deals with geometrical transformations of an assembled unit to obtain its variant, under which a new product is understood which satisfies the condition: it fulfils the same main function as initial assembly and it differs from the initial product by the characteristics of parts (forms, number, location) , and / or the connections between them. A classification of geometrical transformations and heuristic methods for their realization are proposed. The methods are represented by a heuristic algorithm and illustrated by examples.
