Abstract
A method of analyzing structural vibration according to one aspect of the present invention includes reception of data from a plurality of sensors on a structure, filtration of the data to exclude data outside of a selected frequency band, association of sensor locations with locations on computer model, and generation of an animation which displays the structural vibration.
Claims8
A method of analyzing structural vibration, comprising:
- receiving data from a plurality of sensors on a structure, said receiving comprising:
- mounting a first sensor to the structure to measure data along a first axis;
- mounting a second sensor to the structure adjacent to the first sensor to measure data along a second axis that is perpendicular to the first axis;
- mounting a third sensor to the structure adjacent to the first and second sensors to measure data along a third axis that is perpendicular to the first axis and the second axis;
- filtering the data to exclude data outside of a selected frequency band;
- associating each sensor location with a location on a computer model of the structure;
- and
- generating an animation of the filtered data.

- receiving data from a plurality of sensors on a structure;
- filtering the data to exclude data outside of a selected frequency band;
- associating each sensor location with a location on a computer model of the structure;
- and
- generating an animation of the filtered data, said generating comprising:
- receiving a computer model orientation selection;
- determining a magnitude of deflection of each of the plurality of sensor locations at a selected time from the filtered data;
- recording an image displaying the plurality of sensor locations at the selected orientation reflecting the deflections from said step of determining a magnitude of deflection
- selectively repeating said steps of determining a magnitude of deflection and recording an image displaying the plurality of sensor locations at a plurality of time intervals to obtain a desired quantity of images;
- and
- displaying the recorded images in succession to provide an animation of the filtered data.
