Research activities of the Department of glass and ceramics machinery

The Department has participated in a basic and applied research, provided teaching specialized in "Glass Producing Machines and Robotics" as well as teaching basic studies at the Technical University of Liberec. It has taken an active part in cooperation with the leading companies of the glass and ceramic industries in the Czech Republic, and also had contacts with other important home and foreign partners in this sphere.

The research at the Department of Glass Producing Machines and Robotics can be divided into fields as follows:

  • Numerical simulation of glass melt forming processes (pressing, press-and-blow process) and subsequent handling of products on the hot end of production lines. Operational and model measurements of machine forming of glass melt.
  • Design of handling devices and industrial robots, optimization of handling flows, design and optimization of effectors and peripheries for the handling of glass.
  • Design of machines and devices for the glass industry, and optimization of the forming process, glass moulds and plungers.
  • Interpretation of data obtained during experiments as well as from the industrial practice using statistic tools and fractal geometry.
The basic orientations of the Department´s applied research are the numerical simulation, handling, measurement, design, and data evaluation.
The numerical simulation is concentrated especially on the glass forming process, distribution of temperature fields, and handling with products. The Department has obtained excellent results in these spheres. The numerical simulations are based on the data obtained by primarily temperature and temperature field measurements made during manufacture. The Department has at its disposal a broad spectrum of instruments and devices for temperature measurements (thermocouples, pyrometers, thermovision cameras).
Results of the computer modelling are applied on the optimization of the process and tool design, and - in the case of the computer simulation of handling processes - on the optimization of the contact tasks and dynamic behaviour of the system.
The design and optimization of handling flows, effectors, and peripheries including numerical simulations and verification using functional prototypes.
The evaluations of data obtained from the practice and experiments are carried out using own as well as commercial software tools. Statistics and relatively new tools of so-called fractal geometry are used. Surface pictures, time series and material boundaries and such like can be described.
