Research and development of agricultural and forestry machines technology
We specialize in advanced testing and analysis by conducting comprehensive testing of innovative machines and equipment used in agriculture, forestry and food industry. With passion and experience, we are engaged in comprehensive structural analysis, strain testing, fatigue life and dynamic property evaluation, as well as functional testing of machinery and equipment. Using the latest technologies, such as FEM analysis, photogrammetry, and experimental modal analysis, we aim to optimize and ensure the safety of structures. Our activities are aimed at minimizing the risk of failure, improving energy efficiency, and adapting machines to the specific requirements of technological processes. We proudly support innovation and technology development, striving for excellence in every project we undertake.

Testing the dynamic properties of mechanical objects using experimental modal analysis methods
The method of experimental modal analysis is a technique for investigating the dynamic properties of real mechanical objects. The method allows the determination of natural frequencies, vibration forms and values of damping coefficients. When examining an existing object, the analysis can be carried out using the methods:
- experimental modal analysis – by introducing an excitation (force) into the system,
- operational modal analysis – the dynamics of the object results from the excitations associated with the operation.
Modal analysis is often used in machine diagnostics. The method makes it possible to compare the excitation frequencies of the system with the natural frequencies. Overlapping of these values leads to resonance phenomena and machine damage.

Determination of the operational vibration pattern (ODS)
This method is known by its English name ODS (Operating Deflection Shape) or Running Mode and allows the determination of the mode of dynamic deformation of a structure due to the operating loads acting on it. The deformation of the structure is determined by the relative movement (vector quantity) of a selected point of the structure with respect to the others. The operational pattern of vibration depends on the value and location of the excitations and on the dynamic characteristics of the system. The ODS method is based on direct measurement of the operational transmittances between selected points of the operating structure.
The method allows 3D visualisation of machine vibrations.
