Abstract
Engine isolate mounts such as laminated high damping elastomeric bearings, commonly used in automotive and aerospace applications, provide a simple means of isolating the structure of car/aircraft from the engine motions. The key properties of the elastomer are dynamic modulus and damping. The effect of strain amplitude, repeated cycling, and temperature influence on these properties are also important to evaluate the potential engine isolate mount elastomers, such as natural rubber (NR), polybutadiene rubber (BR), Nitrile Rubber (NBR), epoxidized natural rubber (ENR), Neoprene (CR), Poly(Methyl Methacrylate (PMMA), polyurethane (PU), nanoclay-modified PU/polypropylene oxide-polyethylene oxide copolymer with LiClO4 20 wt% (PEL) blends system, ethylene–propylene–diene monomer (EPDM)/nylon 6 blend systems, and so on. All above elastomers or corresponding composite materials and their vibration isolating properties, including the correlations between damping factor, energy loss, damping constant, and vibration transmissibility ratio, are introduced. As a result, the selection principles of elastomers for the engine isolate mount are provided.
