This video was sent to us by one of our customers. It shows how a Prosig P8000 was used to measure the vibration transmitted through different configurations of bicycle suspension. Two are traditional setups (a rigid bike and a dual suspension one) and the third is a new interconnected suspension (likened to a railway bogie). This [...]

The following application note describes the test and measurement process for the fatigue testing and development cycle of a component. Strain gauges were used to monitor the strain levels in a particular suspension component. The component had been known to fail at various intervals. A predicted life for the component was required to analyze the feasibility of the its continued use or to see if a design change was required. The component under test (Figure 1) was an automotive suspension component, specifically a tie rod. The testing was carried out by a major automotive manufacturer. Not all systems vary linearly. One very well known case is, of course, thermocouples. International standard curves are available for these so they present little difficulty. The issue discussed here is determining a calibration curve and if appropriate reducing to a polynomial. |
