Today’s engineers in vibration, structural, acoustic and environmental test/analysis face a challenge to get to grips with modern equipment. PC based software and DAQ systems appear to make the engineer’s life easier, they seem to work straight out of the box. However this is a dangerous path to follow. Fundamentally the responsibility remains with the engineer to make a judgement about the accuracy of their data. Unless they understand what they are doing at an engineering level they can over or under engineer products very easily due to assumptions. Practical training courses in the relevant subjects is essential to allow engineers to develop the gut feelings. This skill can capture errors and incorrect measurements before they are used for design or reliability decisions.
