摘要

Problem vezan uz izbor materijala u realnoj konstrukciji s definiranim elementima opterećenja i deformacija (elastičnosti), te nemogućnost primjene standardnih metoda za odabir najoptimalnijeg rješenja rezultiralo je razvojem postupka ispitivanja elastičnosti konstrukcija funkcionalnom vezom opterećenja i deformacija. Postupak ispitivanja karakteriziran je povezivanjem opterećenja i deformacije relacijom F; M; T=f(ε) ili obrnuto, ε=f(F, M, T) za realne konstrukcije s elementima simulacije opterećenja. Ove relacije ostvarene su sustavom koji čine: hidraulička jedinica s hidro-cilindrima (8) preko kojeg se vrši opterećenje konstrukcije, te senzora sila i deformacija (2, 3) povezanih s upravljačkim i kontrolnim sustavom (9, 10). Paralelnim mjerenjima deformacija i pomaka preko upravljačkog sustava i kontrolnog panela računala (10) ostvaruje se navedena relacija u smislu elastične linije ispitivane konstrukcije ili materijala.The problem associated with the choice of materials for the actual construction with the defined elements of load and deformation (elasticity) as well as the disability to apply the standard methods to select the most optimal solution have resulted in the development of the procedure for testing the elasticity of the constructions by a functional relation between the load and the deformation.BR/ The testing procedure is characterized by relating the load and the deformation through the relationship F; M; T = f (ε) or vice versa ε = f (F, M, T) for the actual constructions with simulating load elements. These relationships are achieved with the system consisting of:BR/ a fluid-operating unit with the fluid-driven cylinders (8), which load the construction, and the force and deformation sensors (2, 3), connected to the control and regulation system (9, 10). The above relationship is effectuated by parallel measurements of the deformations and displacements, via the control system and the control panel of the computer (10), and realized as an elasticity line of the investigated construction or material.
