... coupling system are calculated, and the resonance is analyzed by combining the modal energy and Campbell diagram. It is found that when the meshing frequency coincides with the seventh- and eighth-order natural frequencies, resonance is easy to occur. The influence of different parameters on natural...

... coupling are defined to measure the decoupling level of the redundant parallel mechanism in terms of two generalized matrices. Furthermore, an algebraic solution method for natural frequency equation of the mechanism is utilized to obtain the natural frequency by means of the Cholesky decomposition method...
