摘要: In an earlier paper [1] a method was presented for calculating eigenfrequencies and modes of vibrating system whose modifications consist adding point supports. another [2] generalization the reference establishing vibration characteristics complex continuous systems which are composed several (base or known) systems. this (the modal constraint method) is applied to discrete The base calculated with aid of, instance, finite element used established vibrational modified may addition removal and/or reduction work as compared direct solving problems significant, especiallyfor large degree-of-freedom problems.
