Equipment for adaptation in microtribu00f4metro with rotational variable differential transformer type sensor rvdt for execution of tribological tests, with the measurement of the friction coefficient and wear rate on biomaterials used in orthopaedic prostheses of the knee
Equipment for adaptation in microtribu00f4metro with rotational variable differential transformer type sensor 'rvdt', for the implementation of tribological tests, with the measurement of the friction coefficient and wear rate on biomaterials used in orthopaedic prostheses of the knee.The invention aims to an equipment built in AISI 304 stainless steel, or other material support, with bearings or bearings, to be adapted to a microtribu00f4metro, supporting the proof bodies designed to simulate the contact surfaces and the movime Ints a prosthetic orthopaedic when implanted, allowing, in this way,The realization of the balance between the tilting surfaces of test, when the drive of the microtribu00f4metro.o angle of oscillation of the ventilation system, which is characterized by having a variable amplitude oscillation angle.A rotational variable differential transformer type sensor 'rvdt' connected to the equipment, along with a linear variable differential transformer type sensor LVDT 'native' mircrotribu00f4metro allows to obtain the value of the friction coefficient, and therefore the values of rates of Des Spend the pair tribological test object.The collection of data from the sensor 'rvdt' and the signals of the LVDT '' for the processing and obtaining the values of the forces arising during the test is carried out through a data acquisition plate connected to a microcomputer.
