Abstract

Inventia se refera la un stand pentru încercarea la oboseala a structurilor de aerodina, prin solicitari mecanice variabile, în prezenta unui cîmp termic. Standul pentru încercarea la oboseala a structurilor de aerodina este prevazut cu un dispozitiv automat de generare si control a cîmpurilor termice, similare celor existente în zobr în învelisul structurii, dispozitiv care cuprinde niste module de alimentare automata cu energie electrica, în numar egal cu numarul zonelor de temperatura constanta, care discretizeaza încarcarea termica a învelisului structurii, aplicarea efectiva a solicitarilor mecanice variabile cît si a solicitarilor termice în structura, realizîndu-se prin intermediul unor plachete electrotermice lipite pe învelisul structurii si legate de sistemul de pîrghii cu ajutorul unor benzi textile, al unor rulouri si al unor cabluri, plachte electrotermice conectate,...The invention relates to a stand for fatigue testing of aerodynamic structures by variable mechanical stresses in the presence of a thermal field. The stand for fatigue testing of aerodynamic structures is provided with an automatic device for generating and controlling the thermal fields, similar to those in the zobr in the structure shell, a device comprising automatic power supply modules in the number equal to the number of zones of the constant temperature, which discretize the thermal loading of the structure shell, the effective application of the variable mechanical stresses and of the thermal stresses in the structure, realized by means of electrothermal plates glued on the structure shell and connected to the system of levers by means of textile strips, of rolls and cables, connected electrothermal sheets, ...
