“…To receive negative value of resistance described by equation there are two possibilities. First is to take the value of parameter χ again below required range ( 6 This relates to combined case, while the stiffness c 5 is with the negative value and the χ is also checked while taken below the range (6).…”

“…Interesting application was also presented in [5] where a novel isolator with negative resistance electromagnetic shunt damping has been applied. Synthesis of mechatronic discrete systems is well known, and has been introduced by the authors inter alia while comparing the active and semi-active damping methods in [6] and passive with active types in [7]. Following works [1][2][3][4][5][6][7], authors introduced the problem of designing of mechatronic discrete systems with negative value elements [8], by use of synthesis method.…”

In the paper, the problem of negative resistance has been studied. Considered systems are limited to mechatronic discrete structures that contains mechanical part and piezoelectric actuator in form of stack, connected to external electric network that include the resistance elements which can have and receive negative values. The study have been done based on examples of branched structures, received as a result of solving the reverse task, and is aimed for parameters, limits and constrains evaluation. The paper extends possible applications of piezostack actuators and applied configurations that utilize negative resistance for vibration control.

“…The tests that aim was to verify acoustic emission of both types of the considered systems were carried-out. It should be also mentioned, that introduction of the PDCPD worm gear housing brings new possibilities of implementation of smart materials, for example piezoelectric transducers into its structure and create smart, mechatronic structures [1,2,10,11]. For example, while using the polydicyclopentadiene polymer and RIM technology, non-classical piezoelectric transducer could be implemented into the power steering housing to create a smart structure that could be able to damp vibration or control the technical conditions of the system.…”

Paper presents results of the laboratory tests concerning with measurements of the acoustic emission of the power steering column equipped with a modified composite gear body juxtaposed with the production version of the power steering column with the gear body made of aluminium alloy. The new, developed power steering column worm gear housing is made of a polymer called polydicyclopentadiene (PDCPD) and the Reaction-Injection-Moulding technology was used to produce it (the shortcut of the technology name is RIM technology). Both types of the worm power steering housings were tested to analyse their properties of acoustic emission. Results of the tests are very important considering noise generated during exploitation of a car's power steering system.

“…The problem of synthesis of mechanical systems [8] has been developed by the authors for mechatronic discrete systems, where modelling oriented for various damping performances [9] and comparisons of active and semi-active damping functions [10] were done. While designing of mechatronic discrete systems, by use of selected synthesis methods [8,9], it's possible to determine and use parameters that will lead to negative value elements in the structure [11].…”

In the work the problem of designing of mechatronic discrete systems have been studied for new possibilities of utilization of negative vibration isolation elements. Systems have cascade form and contains the piezo stack actuator and an external electric network connected to the mechanical discrete part. The main focus of the paper is given to the parameters related with negative damping, comparison of usage them based on dynamical flexibilities functions and study on constrains and limitations coming from potential practical application point of view. The new approach is related with placing the issue of negative value damping elements inside the synthesis process. Elements that can exhibits negative value, have been identified and found after distribution of dynamical characteristics, during creation of the mechanical displacement model.
