Application of digital computers in vibration testing and analysis

The paper explains the advantages of digital processing of dynamic data compared to analogue methods. Use of digital computers in processing the data, both off-line and on-line, connected with steady state, transient and random vibration testing is explained with reference to a few actual tests. The practical importance of real-time processing, with the help of on-line digital computers, when multiple shakers are used is described in connection with both steady state and random vibration tests
