Design strength laboratory for large crankshafts

Fatigue and component testing

The many years of expertise offered by our development engineers is even used as a point of reference by engine developers with regard to large engines. In the design strength laboratory, we test the bend and torsion fatigue strength of crankshaft throws in addition to performing rotating bending fatigue tests on material samples.

The bending fatigue strength of large crankshafts is tested on a bending test bench.

It is possible to determine and analyse the bending stresses with the use of strain gauges in the fillets of the crankshaft web.

A torsion strength test has led to a crack appearing in the main journal: the cause analysis can begin.
