METHOD DETERMINING MAXIMUM DISPLACEMENT OF MEMBER OF STRUCTURE IN THE FORM OF PLATE WITH LATERAL BENDING UNDER ACTION OF LOAD DISTRIBUTED UNIFORMLY Russian patent published in 2000 - IPC

Abstract RU 2157520 C1

FIELD: mechanical and civil engineering. SUBSTANCE: invention is related to design-experimental methods of determination of dependence between load and displacement of plates according to results of test of its module, it can be employed for diagnostics of stress-deformed state of construction and machines structures. Method consists in dynamic test of specified structure and in determination of its frequency of vibrations of fundamental tone ( resonance frequency ), in manufacture of plate-model, in its anchoring over outline, in implementation of uniform boundary conditions, in dynamic and static test of model, in measurement of its resonance frequency of fundamental tone and value of maximum displacement and in calculated determination of maximum sagging of specified plate. Plate-model can have any shape with observance of condition of equality of coefficient of form of specified plate and plate-model. EFFECT: simplified requirements to observance of condition of geometrical similarity of specified plate and plate-model, decreased labor input to model testing. 1 dwg
