DEVICE FOR BIOMECHANICAL TESTING OF BONES

The device for biomechanical testing of bones has been constructed so that the driving arbor (3) by means of dinamo metre (7) effects on the levers (8,9,11 and 12) and rack (13), so that by means of a special coupling (17) the twisting of samples should be performed (19) and the angle of twisting can be observed on scale (16) while the moment of twisting is calculated by means of power- scale on the dinamometre (7).In order to perform the examination of sampling for bending, it is necessary to exclude special coupling (17), and activate, by means of driving arbor (3) and dinamometre (7), the levers (8,9,23) and levers (24,25,26) and (27) which by means of a press (28) perform bending of samples (30) so that the overlapping is measured on the digital measurement (29) and the power of bending on dinamometre (7). Uredjaj za biomehaničko ispitivanje kostiju, konstruisan je tako da pogonsko vreteno (3) preko dinamometra (7) deluje na poluge (8, 9, 11, 12) i zupčastu letvu (13), tako da se preko specijalne spojnice (17) izvrši uvijanje uzorka (19) a ugao uvijanja se očita na skali (16) dok se moment uvijanja izračunava preko očitane sile na dinamometru (7). Da bi se izvršilo ispitivanje uzorka na savijanje potrebno je isključiti specijalnu spojnicu (17) pa se preko pogonskog vretena (3) i dinamometra (7) aktiviraju poluge (8, 9, 23) i poluge (24, 25, 26) i (27) koje preko pritiskača (28) izvrše savijanje uzorka (30) s tim što se progib očitava na digitalnom meraču (29) a sila savijanja na dinamometru (7).[The device for biomechanical testing of bones has been constructed so that the driving arbor (3) by means of dinamo metre (7) effects on the levers (8,9,11 and 12) and rack (13), so that by means of a special coupling (17) the twisting of samples should be performed (19) and the angle of twisting can be observed on scale (16) while the moment of twisting is calculated by means of power- scale on the dinamometre (7).In order to perform the examination of sampling for bending, it is necessary to exclude special coupling (17), and activate, by means of driving arbor (3) and dinamometre (7), the levers (8,9,23) and levers (24,25,26) and (27) which by means of a press (28) perform bending of samples (30) so that the overlapping is measured on the digital measurement (29) and the power of bending on dinamometre (7).
