Physixfactor has managed to avoid expensive laboratory tests with virtual models for ROMA Netherlands! The mechanical stresses were localized in the structure, taking into account the construction method. Based on these insights, some adjustments were made to the construction and the order of positioning the panels during construction. In this way we have been able to reduce the voltages by 80%, which means that ROMA can operate its cold stores without any problems in the most extreme conditions. Avoid expensive laboratory tests!
At the invitation of ROMA, Physixfactor presented about virtual reality for the Royal Dutch Association for Cold. Read the full article that appears in RCCK&L: What do you achieve with virtual reality? This presentation takes a closer look at the importance of FEM simulations in industry and the developments in this area in the near future.
Strength calculations are important for structures, but this becomes more difficult when more factors such as temperature and air leakage play a role. This example from ROMA netherland concerns cold stores. Cold rooms and freezers are used to store food, for example meat, for long periods of time at -28°C. Especially in warm countries, problems can arise due to the large difference in outside and inside temperatures, so that a strength calculation becomes necessary to map the stresses due to expansion. ROMA Netherlands is receiving more and more orders for cold stores in warm countries, and the temperature difference between outside and inside can lead to problems with mechanical stresses, resulting in air leakage and therefore energy loss.
The assignment is to set up a strength calculation of panel constructions that also serve as insulation. Come up with proposals on how large cold stores, sometimes as large as 40 x 40 x 80 m³, can continue to function leak-free in warm countries with reduced mechanical stress. A good insulating effect must be guaranteed under all conditions. At the start of the project, the problem statement was clear, including detailed photos of the construction. However, in which direction the solution should be sought was more complex. This has to do with the building and how it is constructed. Physixfactor simulates the construction at its own discretion and, based on close communication with the designers and builders, has been able to define a set of preconditions that apply in practice. During this project, the strength calculations and intermediate results are discussed with the technical teams.
