Investigation of the dynamic behavior of couplings under highly non-stationary processes

The mechanical properties of elastomer couplings are largely dependent on the load rate. The usual manufacturer specifications only valid for load frequencies up to 10 Hz. However, this limit can be exceeded in many applications, so that the dynamic properties of elastomer couplings are not sufficiently known, in particular for overload situations.

Research objectives

The aim of the project is to comprehensively describe the dynamic coupling behavior for highly non-stationary load cases by means of newly defined characteristic values. The focus is therefore on experimental investigation of couplings, and analysis their time-dependent behavior.

  • Coupling dynamic behavior under harmonic load, for example, lasting resonance transit
  • Coupling dynamic behavior under transient and shock-type load
  • Development of a drop tower test bench to investigate extreme and shock-type energy sources
