Strain Gauge Testing

Strain Gauge Testing Compliments Our Analysis Services Perfectly
After manufacture test techniques can be used separately or in conjunction with finite element analysis. It is an essential tool for failure investigations or validation of design.

Equipment struck with a rubber hammer will vibrate at its natural frequencies. This response will be seen by the strain gauges and sensors. A spectrum analysis of the test signals will yield the frequencies associated with the natural modes of vibration. Damping characteristics can also be measured in this way.

The data acquisition equipment and computer can be installed at any location and is self powered. The photo opposite shows an installation in a railway vehicle. Testing does not necessarily mean that equipment needs to be taken out of service. 

After disappointing performance with commercially available bolt sensors MoreVision devised and produced special test bolts by introducing flats on the shank of the bolts and attaching standard linear gauges (photo on the left). The bolts were calibrated in a laboratory load cell shown in the photo on the right.

Bolted joint performance is a common source of problems for mechanical engineers testing a jointed assembly can help us understand poor joint performance. Preload in bolts can be measured using load cells or strain gauged bolts. It is possible to obtain a preload/torque diagram and joint relaxation over a given time period.

Once data has been gathered from test the process of analysis of test results and signal processing can begin.
