摘要

To study the distribution law of random unbalance response of multistage blower, a kind of random emulation experiment method was brought forward, of which the principle is using the simulated val- ues of random unbalance variables generated by computer, through a large number of emulation experiments and statistical analyses, to draw a conclusion about the distribution law of the vibration type and amplitude. Using this method, the study result of D900 blower of a metallurgical factory showed that the vibration types Of blower are mainly the first order vibration type, so it is practical to apply auto-balance technology; the fig- Ure of the distribution law of the blower's amplitude by statistics was also obtained, therefore a series of statis- Tical parameters such as maximum amplitude, average amplitude were defined, which have reference value in Some degree to guide the blower equipment's working condition diagnosis and service action management.
