Strength and failure analysis expert
Pivotech has specialized in the consultation of strength analysis.
Despite company´s young age the company's staff has over 30 years of experience in demanding strength analysis for the structures of technology industry.
Our technical analysis services are mostly implemented by the use of computer-aided FEM analyses. The analysis results are used to optimize the material weight/cost of the structure and to verify the acceptable level of the strength and fatigue.
Our market consists of the most important manufacturers of the pressure vessels, the suppliers for the machine and the forest industry’s equipment and the paper machine industry.
Strength Analysis Services
Engineering analysis can be used to acquire solutions to the wide range of problems, which may include, for example:
- Stress and displacement analysis
- Buckling and other stability analysis
- Vibration analysis (natural frequencies, the response analysis)
- Earthquake analysis
- Non-linear analysis (large deformations, material plasticity)
- Heat transfer, thermal stress analysis
- Determination of the life of the structure (Fatigue)
- Determination of critical crack propagation
- Analysis of composite structures
When we report the results of analysis we give advices to improve or optimize the structure.
We use Femap program for the modeling and NxNastran programs for analyzing the structures.
Some examples of what we have analyzed
- Different sets of paper machines (frames, rolls, cylinders, scrapers ...)
- Steel structures of hoists and cranes
- Machine frames
- Lifting equipments
- Steel halls
- Pipe and transit bridges
Pressure Vessel Analyses
In pressure vessel analysis we use OhmTech’s Visual Vessel Design VVD ® and Termeca’s Standix program and calculation applications that we have developed for the analysis individual parts.
Piping Stress Analyses
Our Company mainly uses FEMDATA’s software, but our staff has expertise also in other software. We do the stress analyses in accordance with the both EN and ASME standards.
Steel Structures Analyses
We perform the analysis of industrial steel structures according to the SFS (B7), EN, and API standards. In addition, we analyze and specify the measures of the device to be used in earthquake zones according to local standards.
