Napredne metode ispitivanja strukture lopatica malih vetroturbina do pojave loma

Abstract

Ovaj rad prezentuje statičko testiranje strukture kompozitne lopatice W55RBVS vetrogeneratora snage do6kW. Testiranje je bazirano na statičkom testiranju strukture do trenutka loma lopatice. Glavni cilj testiranja je definisanje krutosti lopaticeW55RBVS, određivanje maksimalne sile koja dovodi do loma kao i relativni razmah loma lopatice. Kompozitne lopatice W55RBVS, proizvedene u firmi WING.d.o.o., a ugrađuju se na dvokraki vetrogenerator Eoltec Scirocco. Ovaj test je definisan standardom IEC 61400-2. Ispitivanje lopatica je izvršeno u Laboratoriji za aerotehniku Mašinskog fakulteta Univerziteta u Beogradu. Test opterećenja se izvodi do momenta loma lopatice.Rezultat testiranja će biti iskorišćen za redizajniranje lopatice W55RBVS.

This work demonstrates static testing of a composite blade W55RBVS structure for the wind turbines of up to 6kW power. The testing consists of the static testing of the structure up to the moment of the blade failure. The main purpose of the testing is to define and directly verify the rigidity of the blade W55RBVS,to determine the maximum force which leads to failure and the relative span of the blade failure. W55RBVS composite blades, manufactured by the company WING. doo and are installed on a two-blades wind turbine Eoltec Scirocco. This test is defined in the standard IEC 61400-2 /8/. Blade testing is performed in the Aerotechnics Laboratory of the Faculty of Mechanical Engineering, Belgrade University. The load test is performed up to the moment of the blade failure. The result of the testing will be used in order to improve the design of the blade W55RBVS.
