Dynamic Behaviour of Flexible Mechanical Couplings Under General Misalignment Conditions
A complete dynamic model of flexible couplings is presented, and a study of the dynamic actions transmitted between two generally oriented shafts is shown. Numerical results concerning transmitted force spectra show that second and higher harmonics can generally be present, depending on the particular misalignment conditions. Moreover, every component of the resulting force and moment vector seems to be differently influenced by these conditions. Experimental testing was also done, to better understand the problem involved. Correlation between experimental measured velocities and numerically-computed transmitted forces was also proposed. A filtering transfer function model was defined and experimentally evaluated, and some results are given.
