Settings of Radial Corrections of the Gyroscopic Stabilizer

The gyroscopic stabilizer is a device that protects a transported cargo from the undesirable effects of vehicle tilting. The characteristic parameters of such a system are the angular momentum of its gyroscopes and the magnitude of the feedback of the correction and compensation systems, or the so-called radial corrections, which are integral parts of the gyroscopic stabilizer. Radial corrections represent non-conservative forces of positional coordinates and positive feedback. Thus, they could cause instability in the system. Therefore, and in view of the purpose of the gyroscopic stabilizer, parameters of radial corrections must be chosen carefully. In this paper, we will present an approach to the tuning radial corrections of the two-axis gyroscopic stabilizer intended to improve the vibration-isolation of the lying human body during roadway transport in an ambulance car. Our approach starts with roadway design standards, vehicle homologation standards and uses experimentally-obtained real traffic data.
