Special Issue Information

Dear Colleagues,

The development of higher-performance high-precision machinery requires expertise and innovation in a wide range of disciplines, including structural materials, structural design, kinematics, dynamics, vibration, control, actuation devices, sensors, and related electronics.

The objective of this Special Issue is to provide the reader with a collection of articles that present the latest research as well as those reviewing advances in the above areas; in particular, those addressing the design and exploitation of high-precision machines are welcome. This Special Issue plans to give an overview of the most recent advances in the field of the design and operation of precision kinematic systems and their applications in diverse areas. This Special Issue is also aimed at providing selected contributions on research frontiers and potential applications of innovative mechanical constructions with regard to their precision and performance.

Potential topics include but are not limited to:

  • mechatronic systems;
  • robotic systems;
  • exoskeletons;
  • process automation;
  • object diagnostics;
  • forecasting the state of processes and technical objects;
  • drives,

The paper presents the finite element modeling of the dynamic properties of a delta robot attached to a steel frame. A distinguishing feature of the proposed modeling method is the application of the Guyan reduction method in modeling of frame foundations. The frame in question was analyzed in two variants: (i) without attached robot and (ii) with attached robot. Based on the established model, the dynamic properties (i.e., natural frequencies, mode shapes, and frequency response functions) of the frame in the two variants were analyzed. The obtained results were then experimentally verified and validated. It was found that the developed model showed an average relative error for natural frequencies of 4.3% in the case of the frame and 5.6% in the case of the frame with the robot. The paper demonstrated the validity of the proposed model, allowing accurate and fast determination of robotic system dynamic properties. Full article

This paper presents the fundamentals of the design and applications of new worm gear drive solutions, which enable the minimisation of backlash and are characterised by higher kinematic accuracy. Different types of worm surfaces are briefly outlined. Technological problems concerning the principles of achieving a high degree of precision in machining are also described. Special attention is paid to the shaping of conical helical surfaces. Increasing the manufacturing precision of drive components allows one to achieve both lower backlash values and lower levels of its dispersion. However, this does not ensure that backlash can be eliminated, with its value being kept low during longer periods of operation. This is important in positioning systems and during recurrent operations. Various design solutions for drives in which it is possible to reduce backlash are presented. Results of experiments of a worm gear drive with a worm axially adaptive only locally, in its central section, are presented. In this solution, it is possible to reduce backlash by introducing adjustment settings without disassembling the drive. An important scientific problem concerned defining the principles of achieving a compromise between the effectiveness of reducing backlash and the required load capacity of the drive. In this paper it has been shown that in worm gear drives with a locally axially adaptive worm, as well as with a worm wheel with a deformable rim, it is possible to achieve significant reduction of backlash. In high precision drives—for example, those with an average backlash value of <15 micrometers—this can enable more than a two-fold reduction of the average backlash value and more than a three-fold decrease of the standard deviation of local backlash values.
