Original Abstract

Rubber torsional dampers with one degree of freedom are a long-time proven tool for vibration damping in crank mechanisms, especially for passenger cars. Their advantages include, in particular, a relatively simple design and low production costs. The viscoelastic coupling of the damper ring with the basic dynamic system is realized by a rubber spring made of natural or synthetic rubber. The disadvantages of rubber dampers are, in particular, insufficient damping properties of the rubber spring compared with the optimal values resulting from the respective calculation models. This limits the application of rubber dampers to larger power units, such as diesel engines for tractors and trucks. The article deals with the design and optimization of the parameters of an unconventional rubber torsional damper with two degrees of freedom, which even with limited damping parameters of the rubber springs shows a significantly higher damping effect compared to the common design of rubber dampers with one degree of freedom.
