Titre : Dynamic modeling and analysis of shield TBM cutterhead driving system Type de document : texte imprimé Auteurs : Xian Hong Li, Auteur ; Hai Bin Yu, Auteur ; Ming Zhe Yuan, Auteur Année de publication : 2010 Article en page(s) : 14 p. Note générale : Systèmes dynamiques Langues : Anglais (eng) Mots-clés : Boring  machines  Construction  equipment  Cutting  tools  Gears  Tunnels Index. décimale : 629.8 Résumé : In this paper, a generalized nonlinear time-varying dynamic model is established for the cutterhead driving system of a shield tunnel boring machine. A nonlinear multiple input and multiple output state-space dynamic model is also proposed. The dynamic model is simulated to analyze the driving system and the effects of system parameters such as gear backlash and transmission error, larger gear inertia, and load torque on the dynamic response of driving system are investigated as well. A preliminary approach is proposed to restrain speed oscillation and reduce steady-state speed ripple. Through modeling and studying the dynamic model, we refine some important issues that should be given closer attention.
