  This paper deals with the identification of building construction simulation model parameters. We carried out experiments determining construction behavior when actuated by external force applied to real small-scale model. The measured frequency characteristics are used to identify parameters of the simulation model created in the ANSYS APDL environment using the Genetic algorithm. The resulting (tuned) simulation model in the FEM environment will be used to simulate and investigate behavior of buildings using various types of external actuating effects.

  The paper is focused on the issue of vibration and impact sound distribution from stairs and public corridors, including elevators into the protected spaces of a building. The first part of the paper deals with evaluated normalized impact sound levels received from measurement made within the areas of staircases and corridors of carefully selected existing building objects, while the second chapter introduces the first results of observations made on the new landing block, which is especially designed to reduce the transmission of vibration and impact sound.

  Analysis and Modeling of Dynamic Properties if Interactive Drive System, Croatian Metallurgical Society
  journal article in Web of Science
  The recent drive systems are considered as interactive systems containing a range of subsys-tems with different physical nature. This contribution deals with the modelling of mechatronic drive systems using numerical package DYNAST. The theoretical general observations are demonstrated on particular experiments on real system.

  The contribution deals with en experimental measurement of mechanical properties of the bone cement. Where bone cements (PALACOS R and SMARTSET HV) were mixed by two techniques (manual mixing and manual mixing in vacuum) and they were measured under different conditions (temperature, moisture). Measured data were evaluated by statistical analysis. Retrieved results were used for finite element material model of bone cement which is part of hip replacement study by finite element method.

  The paper is focused on the description of the development of single-purpose devices for determining mechanical properties of the segments of human body. The research were focused on the development and design of a device for establishing the abrasion wear of the THR of the hip joint, and for testing spinal segments. On the basis of the gained knowledge, the attention has also been focused on the development and design of a multi-purpose experimental biomechanical device. Its basic idea was derived from Stewart platform, for the modification of which an animation 3D model was developed.
