Collecting and Processing of Vibration Signals by a Microcomputer

This paper presents a measurement system of a shafting vibration test bed. One of the characteristics of the system is that a general purpose microcomputer equipped with general instruments is made useful for measuring vibration, in order to make the system carry out the digitalization and the compu terization to a certain degree. This paper also puts emphasis on how to collect and to process vibration signals by means of selecting hardwares, applying modern signal analysis techniques and working out powerful programs according to the goal of the experiments.
