TRAC R&D Projects


Structural health monitoring of an offshore knuckle boom lab crane is enabled by a Digital Twin. A knuckle boom crane is instrumented with physical sensors providing inputs to an inverse method estimating the applied payload to a FEDEM model. A SAP PEI (FEDEM) twin is used to simulate and extract strain time histories from virtual rosettes. Fatigue analysis are performed real time with hardware in the loop!



Traffic masts and portals can be made frangible to eliminate the need for safety rails. Then they have to be tested by physical or virtual crash tests to prove that ASI and THIV values are within the requirements given in the NS-EN 12767 standard. A vehicle FEM is modeled and used in ABAQUS Explicit crash simulations to get approval for Lattix traffic masts and portals. A scientific paper describing the methods and tools will be published in 2019. The paper and vehicle model can soon be downloaded from this site.


design and optimization of motorcycles

TRAC and MXRR have developed simulation tools for motorbike and race engine simulation and optimization based on the FEDEM software now embedded in the SAP PEI solutions. These tools have been used to optimize HONDA motocross race engines, perform fatigue analysis of drag race engines and analysis, optimization and approval of customized motorcycle frames. Papers describing the tools and methods can soon be downloaded from this site.

Offshore plastic problem

How to stop the increase in offshore plastic vaste

TRAC has taken the initiative to develop a technical solution eliminating the root cause of the offshore plastic pollution problem. By reusing a granulator tecnologie developed by TOMRA, NTNU and ALCOA (2000-2005), bottles can be granulated and easily recycled. The main idea is to install one granulatoir in ships above a certain size. The ships can then deliver granulated plastic bottles at selected harbours. The granulated plastic will then have a value that enables a circuklar economy. The plastic bottles are currently burned or disposed in the sea! On a longer term, local people can collect and deliver bottles for recycling at the same harbours to earn money and reduce the current pollution.
