Development of a Force-path Prediction Model for the Assembly Process of o-ring Type Seals

O-ring type seals are the most commonly used seals worldwide. In spite of possible consequences (e.g. leakage and total machine failure) of a damaged seal-ring due to mechanical overstraining during the assembly process, detailed process expertise is barely existent. The aim of this contribution is to establish a basic understanding for the complex processes during assembly. Therefore contributing elements of elastomeric friction as well as their external influences are analyzed in depth. Finally an outlook on a generalized prediction model of the force-path as a function of relevant factors is given.
