The System of Measurement for Revealing of Micromovements While Testing of the Thigh Endoprosthesis in the Simulator

Анотація

There are a lot of technologies of producing of prothesis, which are different regarding material (alloy) from which the prosthesis is produced. Moreover, the structure of technological process, the ways of processing, using of the equipment, cutting (abrasive) tools and the regime of processing can be different as well.

Before using of the new material (a new combination of the materials) or a new technology of producing of the artificial thigh prosthesis it is necessary to carry out a great number of the experiments. In the special simulators given cycles of loading are applied to the prosthesis. After that, the durability is measured and the damage of the surface is analyzed.

The imperfection of existing measurement systems for defining of influence of outcome factors of technology of producing of endoprosthesis on their durability and longevity is still a problem.

The improvement of the sensor system of the simulator of the work of endoprosthesis of the thigh joint allowed to increase the productivity of the trials on durability of the prosthesis and raise the accuracy of the obtained results 1,7 times.
