Abstract

Inventia se refera la un stand de încercat la oboseala compusa de tractiune si rasucire într-un ciclu pulsator, alternant simetric si asimetric, cu posibilitatea modificarii unghiului de faza dintre tensiuni. Masina de încercat la oboseala compusa de tractiune si rasucire este alcatuita din niste arbori excentrici ce imprima miscari oscilatorii sinusoidale unei piese si, deci, si unei epruvete legate cu un capat de aceasta si cu celalalt capat, la batiul masinii, iar în vederea modificarii defazajului dintre tensiuni, se utilizeaza un cuplaj format din niste semicuplaje cu ajutorul carora se poate roti un arbore cu unghiul de faza dorit fata de arborii care se mentin în timpul reglajului în stare de repaus, oprirea masinii fiind comandata automat de un circuit electronic în momentul ruperii epruvetei, dupa un numar de cicluri de solicitare, înregistrat de un contor.The invention relates to a fatigue test stand composed by traction and twisting in a pulsating, alternating symmetrical and asymmetric cycle, with the possibility of changing the phase angle between voltages. The traction and twisting fatigue test machine is made up of eccentric shafts that prints a sinusoidal oscillatory motion of a piece and therefore also a specimen linked to one end and the other end to the car's tail and in order to modify the phase shift of the voltages, a coupling made up of some semicuplates can be used to rotate a shaft with the desired phase angle to the shafts that are maintained during the idle setting, the machine stop being automatically controlled by an electronic circuit at break of the specimen, after a number of loading cycles, recorded by a counter.
