| Estonian abstract: | Leiutis kuulub materjalide uurimise ja analüüsimise valdkonda, täpsemalt liha mehaaniliste omaduste määramise meetodite hulka ning on kasutatav liha õrnuse määramisel. Gravitatsioonilise impulssmeetodi iseloomulik tunnus on see, et liha proovitükk lõigatakse läbi ^-kujulise lõiketera vabal langemisel liha proovitükile. Lõikamise protsessi käigus liha proovitüki läbimisel väheneb ^-kujulise lõiketera kiirus liha, sealhulgas veiseliha mehaanilistest omadustest lähtuvalt, sealhulgas sitkusest tulenevate takistusjõudude mõjudes lõiketerale. Lõikamise protsessi lõppedes mõõdetakse jõuanduriga lõiketera jääkjõudu ja selle mõju kestust, kusjuures fikseeritakse jääkjõu mõju lõpp ja algus, mis registreeritakse andmesalvesti (arvuti) poolt. Saadud andmete põhjal arvutatakse impulss ja lõikeenergia. | |
| English abstract: | The invention belongs to the field of material research and analysis, in particular, to the methods for estimation the mechanical traits of meat, and it can be used for estimation of the tenderness of meat. A characteristic trait of the gravitational impulse method is that a sample segment of meat is cut through with a ^-shaped shear blade at its free-fall to the sample meat piece. In the cutting process, the speed of the ^-shaped shear blade, passing through the meat segment, decreases due to the mechanic traits of meat, including the impact of toughness-deduced resistance force on the shear blade. At the end of the cutting process, the residual force of the shear blade as well as the durability of its impact are measured by a force transducer; thereby the end and start of the residual force impact are fixed, being registered by a data recorder (computer). On the basis of this data impulse and shear energy are measured. | |
