Using digital acquisition techniques we can acquire data to 32kHz on up to 32 channels simultaneously in the field. Combined with state of the art post processing software both resonant and forced response can be identified on operating machinery and equipment. With predictive analytical tools these results can be correlated to the experimental results and modifications proposed to find innovative solutions to complex vibration problems. In addition both experimental and analytical modal analysis can be conducted to undertake structural modifications to reduce the overall vibratory response.
