METHOD DETERMINING INTEGRATED CHARACTERISTICS FOR STRUCTURES IN THE FORM OF SPRINGY PLATES AND PRISMATIC BARS WHICH FORM AND CROSS-SECTION HAS SHAPE OF UNSPECIFIED TRIANGLE AND PARALLELOGRAM CORRESPONDINGLY

摘要

FIELD: measurement technology. SUBSTANCE: proposed method consists in fabrication of specimens, in their testing in agreement with operational conditions, in experimental establishment of examined integrated characteristic for them and in theoretical computation of value of sought-for characteristic for any element of preset assemblage with use of obtained experimental results. Three specimens in the form of isosceles, acute-angled triangles and three specimens in the form of isosceles obtuse-angled triangles are fabricated and tested for elements of triangular shape. Results of tests are utilized to construct analytically curves " integrated characteristic-base right angle of isosceles triangle " with due account of known decision for region of regular triangle limiting distribution of entire assemblage of integrated characteristics for triangular regions. Three-four specimens in the form rhomb are fabricated and tested for elements of parallelogram shape and results of tests are employed with due account of known decision for square region to construct curves " integrated characteristic-shape factor " limiting distribution of assemblage of integrated characteristics for parallelogram regions. EFFECT: reduced number of tested specimens. 4 dwg
