Dynamic Modelling of a Hydraulic Engine Mount Including the Effects of Elastomer Aging
In this article, the effect of material aging of an elastomeric main spring (MS) inside a hydraulic engine mount (HEM) on its dynamic performance is investigated. A set of HEMs aged under realistic operational conditions are used to create an empirical material aging model of the elastomer at two different temperatures (35°C and 95°C) using dynamic mechanical thermal analysis (DMTA).
