Testing frames for e-mobility
Durcrete

Durcrete, a cement-bound mineral casting specialist in mechanical engineering, will be exhibiting its mixture for machine beds and test frames, which it developed together with Dyckerhoff using specially treated aggregates. The ultra-high-performance Nanodur E80 concrete has a modulus of elasticity of over 80,000MPa and is therefore 50% more resistant to deformation and stiffer than the classic mineral casting formulations based on epoxy resin. It enables machine deformations to be significantly reduced and natural frequencies to be drastically increased.

The base frame forms the solid foundation of any measuring device. If vibrations need to be significantly dampened and high thermal inertia is required at the same time, solid cast materials such as epoxy resin-bonded mineral casting or cement-bonded ultra-high-performance concrete (UHPC) are ideal for the manufacture of machine beds. This new material doubles the rigidity of components while minimizing deformation and maximizing the natural frequency.

This new material enables manufacturers of e-mobility test benches to bring the natural frequencies of the test rigs beyond 25,000rpm, as seen in the drives of electric engines in cars.
