Abstract

Przedmiotem zgłoszenia jest przyrząd do badań ścięgien w warunkach obciążeń statycznych i zmiennych, przeznaczony do wyznaczenia zależności siły w funkcji odkształcenia F = f(?) w warunkach obciążeń statycznych oraz zależności siły w funkcji liczby cykli F = f(N) w warunkach obciążeń zmiennych. Obciążenie zmienne ma charakter odzerowo - tętniący lub jednostronny. Badania można prowadzić na sucho lub w warunkach in vitro. Przyrząd charakteryzuje się tym, że złożony jest z ramy (1), do której za pomocą przegubu (H) o jednym stopniu swobody mocowany jest czujnik przemieszczeń I20, za pomocą przegubu (K) o jednym stopniu swobody czujnik przemieszczeń II21, za pomocą przegubu (E) o jednym stopniu swobody siłownik hydrauliczny (18) za pomocą przegubu o jednym stopniu swobody dźwignia (l7), przy czym pomiędzy dźwignią (17) a ramą (1) usytuowany jest zbiornik osadzony przegubowo do dźwigni (17), przy czym do ramy (1) poprzez przegub (A) mocowany jest siłomierz z górnym uchwytem mocującym (3), poniżej w osi symetrii usytuowany jest dolny uchwyt mocujący (6) połączony trwale do dna zbiornika mocowanego poprzez przegub C do dźwigni (17), której jeden koniec zamocowany jest do ramy (1) przez przegub, a drugi koniec poprzez przegub do siłownika hydraulicznego (18) mocowanego do ramy (1) za pomocą przegubu zaś na uchwycie (6) poprzez łożyska kulkowe, mocowane jest śmigło (9) połączone z silnikiem elektrycznym za pomocą sprzęgła wału napędowego, koła pasowego i pas napędowego na dnie zbiornika mocowana jest grzałka (7) zaś w ścianie zbiornika zamontowane są trwale dwa czujniki temperatury.The subject of the application is a device for testing tendons under static and variable load conditions, designed to determine the force dependence as a function of deformation F = f (?) Under static load conditions and the force dependence as a function of the number of cycles F = f (N) under variable load conditions. The variable load is zero-pulsating or one-sided. The tests can be carried out dry or in vitro. The device is characterized by the fact that it consists of a frame (1), to which a displacement sensor I20 is attached by means of a joint (H) with one degree of freedom, by means of a joint (K) with one degree of freedom displacement sensor II21, by means of a joint ( E) with one degree of freedom the hydraulic cylinder (18) by means of a joint with one degree of freedom lever (l7), with the tank hinged to the lever (17) between the lever (17) and the frame (1), with the frame (1) through a joint (A) a force gauge with an upper fastening handle (3) is attached, below in the axis of symmetry there is a lower fastening handle (6) permanently connected to the bottom of the tank attached via joint C to the lever (17), one end of which is attached is to the frame (1) through the joint, and the other end via the joint to the hydraulic cylinder (18) attached to the frame (1) by means of a joint, and on the handle (6) through ball bearings, the propeller (9) is attached connected to the electric motor by means of a drive shaft clutch, pulley and drive belt a heater (7) is attached to the bottom of the tank and two temperature sensors are permanently mounted in the tank wall.
