FIELD: mechanical engineering.
SUBSTANCE: invention is used to provided free thermal deformation of articles. Proposed method of fastening comes to mating support units of article with corresponding support units of base. According to proposed method one of article support is fixed relative to support units of base, and mechanical links are applied in support units of articles lying on lines intersecting fixed support unit of article. Said links provide possibility of linear displacements of support units of articles relative to support units of base along said lines. Beginning of Cartesian coordinate system is aligned with fixed support unit of article. One of coordinate planes is aligned with plane of which article support units lie and coordinate axes forming coordinate plane are aligned with lines intersecting fixed support unit of article on which great number of support units of article are located, but not less than one, except for fixed unit, on each line aligned with corresponding coordinate axis. Then mechanical links are applied to support units of articles not lying on lines aligned with said coordinate axes to provide linear displacement relative to corresponding support units of base in said coordinate plane.
EFFECT: provision of freedom of thermal deformation of extended articles in planes of mating of support units of article and base when direction of heat flows is not known preliminarily or temperature field is not homogeneous.
