Validation Through Finite Element Simulation of the Behaviour of a Polyurethane Shock Absorber Under In-Service and Extreme ConditionsFerreño Blanco, Diego | Cicero González, Sergio | Carrascal Vaquero, Isidro Alfonso | Meng Ruiz, Enrique |
The safety rules for the construction and installation of lifts, currently in force in Europe, include several requirements concerning the behaviour of the shock absorbers when stopping an elevator. In this paper, a finite element model simulating the behaviour of a cellular polyurethane shock absorber has been developed. The material mechanical behaviour was simulated by means of an elastomeric foam theoretical model, previously calibrated in a former paper. Several in-service and extreme condition scenarios have been analysed with this numerical model, thus verifying the fulfilment of the requirements of the standard.
