The thesis concerns the experimental analysis of a patented device, namely Marcantonini's torque converter, which is based on the inertial moments produced by rotating eccentric masses around a common axis to transfer torque from the input shaft to the output one. The goal is to perform a dedicate experimental analysis on this device, according to transient and steady-state operating conditions. The first part of the study is focused on the set-up of the test bench, deepening the technical characteristics and input/output connectors settings of its hardware components, in order to realize the correct configuration mode and to avoid measurement errors during the test cases.
