Automation – KI – ML – Digital Twins

Automation – KI – ML – Digital Twins

AI (Artificial Intelligence), ML (Machine Learning) and Digital Twins are currently the central topics in software development.

Lauterbach Verfahrenstechnik GmbH is working with partners from research and industry on a project to optimize manufacturing processes using software technology based on digital twins combined with machine learning. In 2022, the project basis was created for this.

New Model Rectangular Vessels

New Model Rectangular Vessels

Rectangular vessels represent high requirements in terms of operationally suitable design and necessary strength. This sophisticated design is being used more and more frequently in apparatus engineering. In most cases, these tanks are structurally reinforced by welded-on ribs.

With our new FELV module for rectangular tanks, we offer the possibility to check reinforced rectangular tanks for strength quickly and efficiently. The vessel can be subjected to internal or external overpressure, wind and/or earthquake loads or external loads in general and a hydrostatic load.

The input of your geometry data, materials and loads is done in a user-friendly way via a LV input mask. The calculation then runs in an external application, which visualizes, tabulates and documents all data entered and obtained. This gives you a complete overview of your project and your current design at any time.
