Technological Science

Keywords: manual material handling, postures, repetitive motions, ergonomic quality of tools, ergonomics, safety engineering.

The fit between human capabilities, limitations and what is required by technology or environment is particularly important when the goal is to ensure a sustainability of workforce or to design technology and environments that are easy to use. In order to achieve such goals, data about technology related risks is needed in the decision making.

Our competency covers a wide range of subjective and objective methods, which can be implemented during the planning or other phases in the product’s or environment’s lifecycle.  Subjective methods are used for risk assessment in existing work systems and our competency includes methods that are described in the series of “EN 1005 Safety of machinery. Human physical performance” and methods endorsed by relevant governmental agencies such as NIOSH (USA), HSE (UK) or BAuA (Germany). Meanwhile in the planning phase data about human performance and physical capabilities are required in order to make design decisions. Our experience and competency allow to tailor the measurement devices according to the needs of the task.

Keywords: NDT, non-destructive testing, tomography, X-ray, voxel.   

The laboratory includes the X-ray computer tomography scanner, YXLON FF35 CT, manufactured by the German company YXLON International GmbH. The system has two different powers of the X-ray tube: 190kV and 225kV. This configuration allows the device to be applied in a wider range of test specimens for desired precision. Full version of the VG Studio Max 3.2 software package is used for the data analysis. The dimensions of the largest body that can be scanned are Ø 300 mm x 500 mm. The maximum allowed load of the rotating table is limited to ensure that the total mass of the test object together with the fixture does not exceed 30 kg.
