The study outlines the geometric analysis of motions executed by the Stewart platform and operated in the environment of a simulator for driving learning to be used by disabled people. The analysis was carried out on the basis of results obtained from the resolved kinematic problem for the inversed platform.

This work presents ideas for a passenger car driving simulator for teaching the disabled. The functional structure, design assumptions, and the concept and operation of the proposed simulator are presented.

The paper presents the problem of vibration re-duction in the identified machine drive systems in the form of single or multi-stage gear units. The reduction method was based on using an active synthesis making it possible to obtain a desired mechanical effect by properly selecting the dynamical system properties. The desired dynamical properties are understood throughout the paper as a se-quence of resonance and anti-resonance frequencies in the form of dynamical characteristics. The properties assumed in such a way constitute a starting point for the parametric and structural identification of discrete oscillating systems. DOI: http://dx.doi.org/10.5755/j01.mech.20.2.4476

In this work the method of active synthesis of mechanical systems in accordance with the desired frequency spectrum has been formulated and formalised. Active synthesis of a proportional regulation system has been performed in accordance with the method formulated and a verification of the correctness of the results has been carried out.

The paper presents the problem of stability and vibration reduction in designed discrete mechanical systems. The method of stabilisation and reduction has been based on active synthesis, which makes it possible to obtain the desired mechanical effect through the proper selection of dynamic properties of the system, including the calculation of the active force as a function of the system force feedback.
