MATERIAL PROPERTIES OF RUBBER-CORD FLEXIBLE ELEMENT OF PNEUMATIC FLEXIBLE COUPLING

摘要

This paper deals with to describe the material properties of rubber-cord elastic element necessary for assessment of pneumatic-flexible element by means of Finite Element Method (FEM). A viscoelastic constitutive model Of rubber-cord composite is established by introduction of strain energy density function. For description of material properties of rubber-cord element is used a curve, Le. the experimentally determined curve Of Mooney-Rivlin material. The relevant constants were determined on the basis of tensile test of rubber-cord element. Results are presented for a Material of pneumatic-flexible element of differential pneumatic flexible coupling with autoregulation.
