- First paper to provide general criterion and confirming simulations to explain bouncing motions due to partial contact in rotor dynamics. Arising as part of Programme Grant EP/K003836/1, motivated by problem in 2 sectors Rolls Royce (windmilling of engines) and Schlumberger (violent drillstring vibrations). Earlier paper by Zilli had proposed a criterion for single mode rotors. Here this is generalised to any rotor and explained by concept of internal resonance. The work led to permanent position for Shaw at Swansea and new experiments & mathematical analysis. Significance because of industrial ubiquity of rotordynamics and open problem to describe damaging bouncing vibrations.
