Presentation

Test benches with a high rigidity and stiffness using UHPC

Due to the high natural frequencies of electric motors, it is necessary for the bases of test equipment to be very rigid so that resonance frequencies do not distort the recording of test results. Cast iron and welded steel constructions reach their limits here. The presentation describes the use of a solid, cement-bonded mineral casting (ultra-high-performance concrete or UHPC) with a modulus of elasticity of 80,000MPa for testing tables and benches.
