Baraev A. � Investigation of the wave processes in the coiling flexible coupling at dinamic load

Waves, arising in the coiling flexible oupling (CFC), are investigated. It is shown that there are three wave types occurring under dynamic load in the CFC: two waves are longitudinal-and-torsional and they propagate along the CFC, and one waveis transverse. It is established that depending on the CFC lay direction the longitudinal-and-torsional waves may either untwist or twist it supplementary and determine its deflected mode.
