In the design strength laboratory for automotive crankshafts, we carry out fatigue strength tests on crankshaft throws (bending and torsion fatigue strength) in addition to performing rotating bending fatigue tests on material samples. The high level of success enjoyed by our test engineers in this area means that engine developers and manufacturers are enthusiastic about making use of this service.
The bending fatigue strength of crankshafts for use in cars is tested on a bending test bench developed by ALFING.
The torsion test bench developed by ALFING determines the torsion endurance strength of a car crankshaft by means of programmable automated test sequences.
