CENTRIFUGAL MATERIAL SPECIMEN STRENGTH TEST UNIT Russian patent published in 1994 - IPC

FIELD: strength test of material specimens. SUBSTANCE: test unit has platform 4 with loads 7 and grips 5 for specimen 6, roller 9, cylinders 10, 12, drives 13, 14. During rotation of platform 4 loads 7 apply tensile load on specimen 6. When drive 14 is used, bending load on the side of roller 9 is cyclically varied, at a synchronous displacement of rod 11 and cylinder 12 the trajectory is cyclically varied. The unit is used for test of specimens of different materials. EFFECT: widening of functional potentialities by provision of tests both at static and cyclic variation of radius of trajectory of the line of application and level of bending load. 1 dwg
