METHOD OF ENDURANCE TESTING OF CANTILEVER STRUCTURES

摘要

FIELD: test engineering. ^ SUBSTANCE: method comprises securing the structure to the load-bearing support and exciting flexure vibration by means of a vibration generator, applying longitudinal stretching loading to a given section of the cantilever structure by means of a load generator connected with the section through a flexible link. The epures of flexure moment are inferred from the readings of strain gages and compared with the values presented in the test program. The strain gages are glued in several sections along the length of the structure. ^ EFFECT: enhanced efficiency of tests. ^ 2 cl, 3 dwg
