merna ćelija Explanation: - External Six-Component Strain Gauge Balance for Low Speed Wind Tunnels The external six-component wind tunnel balance designed and manufactured in the Military Technical Institute is described in this paper. The balance is of a platform type. Aerodynamic load which acts on a model in the wind tunnel test section is transferred into the set of six load cells. The relations between the aerodynamic load and the forces measured using the balance load cells are presented. All load cells are gauged with foil strain gauges. The results of the balance calibration are shown. The balance calibration was done using dead weights. Key words: wind tunnel, strain gauge balance, load cell, calibration. - Spoljašnja šestokomponentna aero vaga za aerotunele malih brzina U radu je prikazana spoljašnja šestokomponentna aerovaga projektovana i izrađena u Vojnotehničkom institutu u Beogradu. Prikazana aerovaga spada u grupu spoljašnjih aerovaga sa platformom. Aerodinamičko opterećenje koje deluje na model u radnom delu aerotunela prenosi se na na šest mernih ćelija. Prikazane su matematičke relacije između aerodinamičkog opterećenja i sila izmerenih u mernim ćelijama. Sve merne ćelije su sa folijskim mernim trakama. U radu su prikazani i rezultati etaloniranja aerovage. U toku etaloniranja opterećenja su unošena pomoću tegova. Ključne reči: aerotunel, aerovaga sa mernim trakama, merna ćelija, etaloniranje. http://www.vti.mod.gov.rs/ntp/rad2014/3-2014/6/6.pdf -------------------------------------------------- Note added at 1 hr (2017-08-21 12:18:44 GMT) -------------------------------------------------- Elektrotehnički fakultet u Beogradu FIZIČKO-TEHNIČKA MERENJA:MERENJE SILE, NAPREZANJA I MOMENTA - Merne ćelije (load cell) – konzole na koje se lepe merne trake. Poželjno je da deformacija bude linearna sa primenjenom silom, kako bi i deformacija samih merni traka bila linearna sa promenom sile. http://nobel.etf.bg.ac.rs/studiranje/kursevi/of3ftm/materija... |
