Abstract

In this research, an oleo dynamic torque amplifier has been examined. It is widely used in a wide range of mechanical applications. For this device, during the working phase may arise secondary phenomena that may affect in negative way its use. Therefore, in this research, the limits of applicability of it were determined. Indeed, it has been evaluated the range of variability of the error during the position control phase, detecting an error  minimum for which the system considered is insensitive. This error has been studied in the transitory period, determining its performance using the computer code MatLab Subsequently it has been performed the dynamic study of the considered system examining the function error. Some cases, considering the viscous damping not equal at zero, have numerically been determined. It has been possible to note that the range time of the transitory period decreases when the damping values increase. Besides it is resulted that, if we wish to limit at the minimum the range time of the transitory period, without to change the inertia moment J, we have to change the viscous damping values, F. But in this way, it would cause the drawback to increase the energy dissipation for the system considered, with the necessity to use greater power engines. Instead, the purpose could be equally reached introducing in the control system a tachometer stabilization, or rather, an element able to give a resistant torque proportional at the first derived of the error in function of the time.
