Abstract
One-third-scale models of electrical raceways and their support systems have been constructed to compare the response of a typical rigidly-braced system with that of a proposed flexible support system. An array of instrumentation, including accelerometers, strain gages, and displacement transducers, is used to obtain frequency response data, to determine mode shapes of system components, and to obtain data to validate analytical models of the system. Data are fed through signal conditioners and analog-to-digital converters into a minicomputer for recording and processing. This paper describes (1) the design of the test models such that physical similarity to the full size system is maintained, (2) instrumentation required to obtain the desired data, (3) the test frame and equipment needed to support and dynamically excite the models, (4) the data logging and analysis approach, and (5) comparison of experimental and analytical models.
