“…The use of rotational quaternions in beam and multibody theories has been mostly limited to construct numerically stable and efficient local computational algorithms that avoid singularity problems and accelerate computations (see, e.g. [6], [9], [14], [20], [23], [27], [31]). Zupan and Saje [36] studied the effect of the choice of the parametrization of rotations when integrating rotations from angular velocities using various methods.…”

“…If one uses classical rotation parameters, such as Euler angles or spin vector, it is difficult to determine stability conditions for an explicit integration scheme. This motivated us to introduce a new set of parameters, based on the so-called 'four-mass' concept [8,9], to describe global rigid motion. The position and orientation of the local frame are given by four points whose distances to one another are kept constant during the simulation.…”
