Explicit Momentum Conserving Algorithms for Rigid Body Dynamics

  title={Explicit Momentum Conserving Algorithms for Rigid Body Dynamics},
  author={Gregory M. Hulbert},
Two new explicit time integration algorithms are presented for solving the equations of motion of rigid body dynamics that identically preserve angular momentum in the absence of applied torques. This is achieved by expressing the equations of motion in conservation form. Both algorithms also eliminate the need for computing the angular acceleration. The first algorithm employs a one-pass predictor-corrector scheme while the second algorithm is based upon the staggered time integration approach… CONTINUE READING
