Temperature dependent examination of brake cylinder membrane (Part II) FE Modelling of cord-reinforced rubber membrane behaviour

摘要

The present paper shows two special compression tests and finite element simulations created for the examination of a rubber-cord composite membrane structure used in railway brake systems. The membrane transforms the air pressure growth to unidirectional movement within a wide temperature range. After the material characterization detailed in [1], the authors studied the whole composite membrane structure using specimen level compression tests. Having repeated the measurements at different temperatures it can be concluded that the whole membrane produces the same hardening by decreasing temperature as the reinforcement layer in the membrane. The measurements were also analysed using commercial FE software.
