Experimental identification of mechanical systems behavior is treated in the Laboratory. Calculation methods for support structures and machine elements and components have been developed. In this field there virtually exists 30 years' experience.

Experiments or calculations are employed to determine system quality indicators defined by a group of disturbance subsystems:

  • Temperature and temperature phenomena,
  • Static deformations,
  • Dynamic behavior,
  • Noise etc.

It should be pointed to modern methods developed for modal analysis, stochastic theory of machining system dynamics and non-linear mechanical structures analysis. The problems of experimenting and measurement in the domain of machine structures including structural analysis of machines themselves are all predominantly in the focus of activities. Behavior analysis and synthesis of the chosen machine systems with respect to their functional and disturbance subsystems are performed. Those are the components of flexible technological systems: machine tools, robots, measuring machines and the like. At least initial quality indicators (geometrical and kinematic accuracy) are determined but also some of those defined by a group of disturbance subsystems (static deformations, dynamics, temperature phenomena, wear and friction, noise and reliability). Research is especially oriented to the development of experimental program-computer units having artificial intelligence elements to be used to identify machine systems. Structural analysis embraces static-dynamic experimental analysis linking it to developed computational methods. Long-term research has been conducted on the application of finite elements method for identification of statics, dynamics and temperature pehnomena.

Other methods dealt with in this Laboratory are: modular analysis, stochastic theory of machining system dynamics and non-linear structures analysis, modern methods for finished surface analysis using fractal geometry, optimization of elements and structures, extension of activities to automatic design of machining and technological processes, analysis of machining methods by plastic deformation with the use of MKE and the like. All research activities are conducted through projects and project managers are younger researchers, graduates and PhD students. In the Laboratory a larger number of MSc and PhD theses have been realized. A short list of those theses illustrated by obtained results is given below.
