Process for quality control of products having parts made of elastomeric material.

摘要

A flexible mounting (2) having a ring made of elastomeric material (3) fixedly engaged between an inner metal collar (4) and an outer metal collar (5) is mechanically stressed so that it undergoes a gradual elastic deformation corresponding to a relative displacement of 15 mm between the collars, in a period of 20 seconds. Acoustic transducers (7) previously associated with the flexbile mounting (2) carry out the detection of the acoustic emissions occurring within the mounting itself due to the arising of structure instabilities in the latter while it is submitted to deformation. Transducers (7) convert the acoustic emissions to electric signals that, after suitable amplifications and discriminations, deliver data for a reliable quality evaluation of the mounting being tested. <IMAGE>
