- Storage tanks, bins and silos – vertical and horizontal (strength, stability, seismicity).
- High and low pressure heat exchangers, condensers, tanks, centrifuges and pumps (strength, fatigue, stability and seismic effects).
- Pressure vessels of all kinds (strength, stability, fatigue).
- Computational strength and stability analysis of pair, trio and quartet horizontal beer tanks mutually superposed.
- Explosion and detonation chamber.
- Strength, dynamic and seismic analysis of electron microscopes and auxiliary equipment (electrical console, acoustic boxes, etc.).
- Shell boilers – strength and life service with regard to thermal loads.
Operating accelerations and strain gages measurements
- Preparation, own measurement and evaluation of mechanical vibration in plants with feedback of the results of FEM analyses.
- Measured data analysis and statistics with graphs.
- Preparation and own strain gages measurement supported with FEM analyses.
- Stress evaluation by means of Rain-flow method, respectively RCM (Reservoir Counting Method).
The company AK-Mechanika, s.r.o. provides operating and strain gages measurements for validation of numerical analyses of structures. Measurements are carried out using the measurement system built on the components of National Instruments, Seika Mikrosystemtechnik, Hottinger Baldwin Messtechnik etc. Measured data are evaluated using statistical methods, Rain-flow or RCM (Reservoir Counting Method) and other.
The type and extend of measurement, the type of operation and the method of data analysis must be consulted with our technicians in advance. The measurement report with calibrations and description of measurement chain with photo-documentation is an integral part of technical computational reports.
