Question 2 La manivelle AB du concasseur de roche tourne une vitesse constante de AB = 3 rad/s (antihoraire) pour faire osciller le maillon marteau EF. Les maillons du mcanisme ont les dimensions suivantes : AB = 1.6m BD = 5.3m CD = 5.2 m FD = 5.1 m EF = 3.3 m I Le maillon marteau EF son centre de gravit au point G qui se retrouve a EG = 2.2 m, et les maillons G4 B AB et CD sont quilibrs. Une analyse cinmatique l'instant illustr rvle la position et la motion suivante (Notez que les angles des maillons sont dfinis par rapport l'horizontal au joint dnot par le premier indice): AB = 334 BD = 253.5 CD = 166 BD = -0.19 rad/s BD = 3.47 rad/s 8CD = -0.91 rad/s CD = -0.46 rad/s Si les maillons ont les proprits suivantes: OFD = 11 8FD = -0.99 rad/s FD = 0.48 rad/s EF = 261 8 EF = -0.65 rad/s BEF = 3.06 rad/s MAB = 120+ SN/10 kg MBD = MCD = MFD = 200 + SN kg MEF = 1500+ SN kg IAB = 20 + SN/10 kg m IBD = ICD = 1FD = 410 + SN kgm IEF =1400+ SN kg m Dterminez: a) (11 points) Les forces et moments de d'Alembert de chaque maillon. b) (4 points) Le couple ncessaire la manivelle pour une force horizontale F = SN + 10 kN applique au point F en utilisant la mthode du travaille virtuel. AB = 334 BD = 253.5 BD = -0.19 rad/s BD = 3.47 rad/s 8 CD = 166 CD = -0.91 rad/s CD = -0.46 rad/s FD = 11 8FD = -0.99 rad/s FD = 0.48 rad/s EF = 261 8 EF = -0.65 rad/s BEF = 3.06 rad/s MAB = 120+ SN/10 kg IAB 20+ SN/10 kg m = MBD =MCD=MFD = 200 + SN kg IBD = ICD = IFD=410 + SN kgm MEF 1500+ SN kg IEF =1400 + SN kg m
