Abstract

IPrezenta inventie se refera la un procedeu de masurare a rezistentei la încovoiere prin soc în conditii de temperaturi joase si temperaturi ridicate, precum si la un aparat pentru masurarea rezistentei în conditii de temperatura scazuta si de temperatura ridicata. Procedeul este caracterizat prin aceea ca, în scopul încercarii atît la temperaturi scazute cît si la temperaturi înalte, energia de rupere a epruvetei este transformata de catre un traductor inductiv într-un curent electric invers proportional cu energia de rupere, iar aparatul pentru aplicarea procedeului este constituit dintr-o epruveta care este termostata în conditii de temperaturi ridicate într-o incinta sau în conditii de temperaturi scazute încovoierea realizîndu-se prin cadere libera a unui ansamblu format din niste greutati si o zija, energia de rupere determinîndu-se prin masurarea curentului furnizat de o bobina, curent care ia nastere prin deplasarea unui magnet în bobina.The present invention relates to a method for measuring the resistance to bending by shock in conditions of low temperatures and high temperatures, as well as to an apparatus for measuring resistance in conditions of low temperature and high temperature. The process is characterized in that, for the purpose of testing at both low and high temperatures, the breaking energy of the specimen is transformed by an inductive transducer into an electric current inversely proportional to the breaking energy, and the apparatus for applying the process is consisting of a test piece that is thermostated in conditions of high temperatures in an enclosure or in conditions of low temperatures the bending being realized by free fall of an assembly formed by some weights and a zija, the breaking energy being determined by measuring the current provided by a coil, current that arises by moving a magnet in the coil.
