Abstract: The simulator of behavior of a disabled person driving the car is especially useful equipment. Mainly, the hands and the face of a driver are observed in order to determine facial expressions, slow-motion of the head and eyes, which according to the description of the simulation indicate disturbances of concentration and, in extreme cases may lead to nausea, or even loss of consciousness . So, in the realization phase of the configuration the control system, the need to maintain high standards of safety was taken into consideration. The main problem described in the paper was measuring the acceleration and frequency of vibration during the operation of the simulator [2, 3, 4]. This analysis will help to determine whether any particular circumstances during crash simulations do not exceed the acceleration limit while the driver still feels its effects. It is also important to examine the frequency of vibrations, which during long driving simulator can cause nausea, dizziness or loss of consciousness. This analysis is a part of widely applied CAx analysis performed using special computer platforms that should be properly organized  and helps to expand the range of investigations .
Abstract: This work presents methods of reduction of the vibration of mechanical systems by means of active elements as well as examples of implementation of active reduction of vibration by means of electrical elements , . This work also describes a structural and parametric synthesis, which can be defined as the design of systems meeting specific requirements. These requirements refer to the frequency values of the systems’ vibration. The presented approach i.e. a non-classical synthetic method applied in designing mechanical systems with elements reducing unwanted vibrations. As a result of the synthesis, one can obtain the structure and parameters of the system of required properties. The synthesis may also be applied to modify the already existing systems in order to achieve a desired result [1–3].
Abstract: Piezoelectric actuators are more and more common in many different technical and precision industries. Mechatronic systems which combine them with mechanical models and steering recently are used in plenty practical applications. In this paper, discrete mechatronic systems have been compared relating to known passive vibration isolation method and active that has been additionally introduced to considered systems. Requirements for the systems have been given in form of poles and zeros. Basing on amplitude response functions and dynamical flexibilities, damping performance in both cases has been investigated.
Abstract: In the paper, the modeling and analysis of mechanical subsystem of vibrating continuous-discrete mechatronic system have been presented. This approach was established to nominate the relevance or irrelevance between the characteristics obtained by considered methods – especially concerning the relevance of the natural frequencies-poles of characteristics of beam as the subsystem of mechatronic one. At the beginning of the approach, the modeling and frequency – modal analysis of simply beam as the subsystem of vibrating mechatronic system with constant cross sections are presented. It is the research limitation, that linear continuous transverse vibrating beam is considered (Eg. [1, 2]. Findings of this approach is a fact, that approximate solutions fulfill all conditions for only subsystem, that means vibrating beams, modeled by graphs & hypergraphs and analyzed by different category structural numbers as well [3–5, 6]. Practical implication of this study is that the main point is the introduction to synthesis of transverse vibrating continuous-discrete mechatronic systems.
Abstract: The article presents a hierarchical steering system for developing mobile robots and fulfils the established goal in unknown surroundings. The task was carried out with reference to a cooperative combination of elementary behaviour patterns such as finding destination and avoiding obstacles, and was generated using the Kohonen neural network. The paper has assumed formation shape and considered the right of steering other robots in the formation process. Finally, the proposed solution has been verified.
Abstract: This paper presents an interactive mechatronic device which serves the purpose of rehabilitation of small children with lower limbs dysfunction. It is shown that upon application of EEG technology, EEG sensor has the role of controlling the whole rehabilitation process. The assessment of the degree of the child’s involvement in the improvement process is made on the basis of the obtained course of the brain waves. The achieved level of concentration is further used as feedback in the control loop of the change of multimedia content. Such approach makes the children under rehabilitation notice the relation between their own activity and the reaction of the equipment and thus learns how to consciously focus and stay alert. This new equipment allows the child to do prophylactic and correctional exercises with simultaneous psychological stimulation. This aspect allows using natural abilities of brain development in small children to a maximum degree.
Abstract: This paper presents the results of CFD analysis of the hydrodynamic pressure distribution in slide journal bearings lubricated by non-Newtonian oil. It was assumed that the oil shear stress varies from shear rate according to the Ostwald–de Waele relationship (power law lubricant). The comparison was related to bearings differences only in properties of lubricating oil – Newtonian and non-Newtonian properties; other parameters for both in each case were the same. The Tables show relative decrease of the maximum hydrodynamic pressure value and bearing lift capacity according to the bearing lubricated with Newtonian oil, for different values of bearing relative eccentricity.
Abstract: The paper presents and solves the problem of a discrete reduction in vibration in mechanical systems depending on the desired dynamic properties. The methods for determining the passive values of vibration elements reducing vibrations to the desired amplitude value were formulated. Synthesis was done, using the methods of a discrete synthesis of vibration systems and introducing an assumption concerning the damping element existing in the required system and taking a rheological model as a mass damping model.
Abstract: This paper presents an application of a robotic manipulator in a machining process. Due to the specifics of the process and numerous phenomena which are difficult to be modelled, suitable tool for the robot control are neural networks. This work concentrates on the robot control process. A synthesis of a neural position/force control algorithm is presented. The algorithm was tested by simulation and in actual conditions on a laboratory stand. The work presents the experimental results with their comparison with an adaptive method based on the robot’s mathematical model.
