SIMULATION OF THE GEARS STRESS-STRAIN STATE OF ELBOW ORTHOSIS PLANETARY GEARBOX

Gear transmissions of various sizes are used in various fields of mechanical engineering, automotive, marine, and aerospace industries according to the needs. This paper presents the modeling and analysis of the modal and harmonic characteristics of a planetary gear transmission for an elbow orthosis. Orthoses are used during the rehabilitation of patients in the postoperative period or during the restoration of lost limb functions. When modeling the planetary gear, the connection elements are made of 45 steel and PLA polylactide.

SIMULATION OF THE STRESS-STRAIN STATE AND DETERMINATION OF THE NATURAL FREQUENCY OF THE LABORATORY CENTRIFUGE SHAFT VIBRATION USING ANSYS AND KISSSOFT

The rotor is a key element of high-speed mechanisms that are widely used in various industries, such as laboratory centrifuges used to separate mixtures of different fractions, gas turbines, industrial compressors, engines, and others. The main requirement for such mechanisms is reliability and safety during operation. To ensure the above requirements, it is necessary to determine the stress-strain state of the most loaded structural elements of the system and the dynamic characteristics.

A strain sensor resistent to proton irradiation

Influence of proton irradiation on the properties of Si_1-xGe_x whiskers as strain sensors is studied in this work. On the basis of secondary signal processing the possibility of using such whiskers as a strain sensor’s sensitive element resistant to proton radiation is shown.
