Abstract
A method for visualizing and indicating characteristics of vibration measurement data for a rotating or vibrating object. Specific components are removed from the measurement data or are minimized therein. After removing or minimizing the specific component, the measurement data is indicated in a Campbell diagram.
Claims5
A method for indicating characteristics of rotating apparatus or vibrating apparatus, the method comprising steps of:
- measuring data of vibration by a physical parameter of displacement, speed, accelerated velocity or sound pressure level of a measured object;
- filtering or minimizing a specific element from the data of vibration to provide processed data;
- removing or minimizing specific components from or within the data of vibration;
- and
- indicating the characteristics of the measured object by displaying the processed data as a Campbell diagram such that amplitudes are represented by size of circles, said circles being centered on corresponding coordinates with one axis representing vibration frequencies and an other axis representing a physical quantity of operating frequencies, time, or temperature.
