It is not always possible to predict all the load cases of the structural design with mechanical calculation and therefore it is not easy to have full knoledge of the permissible load capacity based on the characteristics of the material. By measuring physical quantities in situ at interesting cross sections, as well as subsequent analysis, we can get to know the basic construction characteristics, as well as predict the withstand limit loads. Loads can be static or dynamic. While static ones are more predictable with respect to constant forces, masses and loads and easier to measure (stress, pressure, static displacement, force and static moment), dynamic ones are often not (vibrational displacement, dynamic stress, resonant phenomena, forms of vibration). The dynamic impact itself is different, and it can be caused by machines and devices with constant dynamic forces and operating frequencies, but also by time changeable load levels such as climate (wind, sea) or traffic.

 

In cooperation with our partners and state-of-the-art equipment, we can provide periodic measurements but also continuous monitoring of the structure, and this is especially important in changing load conditions where loss or change of structural characteristics occurs more often. Before the measurement, we can determine together with the Client the interesting, ie the most unfavorable cases of load in operation, and make quality preparation and create a test plan. After measuring and analyzing the recorded quantities, we can compare the measured quantities with allowed ones in the mechanical calculation, but also predict the limit loadcases at which the structure is not safe.

 

Finally, we can also optimize the design of the structure, such as stiffening in critical sections or unloading (subtraction of mass), in order to improve and better distribute its static and dynamic properties.

In cooperation with our partners, we perform testing of physical factors in the work environment, namely noise and vibration. Testing of the working environment is one of the tasks of safety at work, and if there is increased vibration or noise, the employer is obliged to do testing at that workplace and ensure the development of work processes. The assessment is performed by comparison with the allowed exposure values specified in the applicable standards after measurement analysis.

 

Noise and vibration not affect just on the working ability of the worker, but can also affect his health. Measurement and analysis can be performed not only in workplaces in the process industry but also in working vehicles, and workplaces that require the use of various self-propelled and hand tools. In cases where the test results do not satisfied the prescribed standards, by help of the analysis we can determine the failures and causes of increased values, such as: malfunction of the machine, devices and tools or inadequate system of workers protection. Based on this, we can propose measures to reduce the impact of certain health hazards in the work environment.
