Abstract
Based on the absolute nodal coordinate (ANC) framework, the dynamics modeling and solution strategy for the multibody system with fractional derivative damper is investigated. The flexible parts are discredited by the ANC-based locking-free shear deformable beam element. The system equations of motion with constant mass matrix are also obtained and solved by the numerical dissipation controllable generalized-a method. The effects of the algorithm parameter and the fractional index on the dynamics responses are also studied by solving the numerical examples. The presented procedures can also be used to solve many other practical engineering problems.
