发明名称 Trending of vibration data taking into account torque effect
摘要 <p>In vibration based mechanical diagnostics, algorithms may extract some feature of a component which may be used as a statistic of the components' health. A measured condition indicator (CI) corresponding to the analysis of the components' health may be a function of transmission error (TE). Because there exists a relationship between TE and the CI for a component that is faulted, the CI is correlated with power transmitted. In drive train components, power may be proportional to measured torque. In terms of diagnostics or trending of a component, it is desirable to reduce the scatter in the measured CI and account for this torque. The relationship between measured CI and torque may be captured over time. An increase in the correlation of torque with the CI would indicate an increase of TE which indicates the propagation of a fault.</p>
