Comparing Vibration On Bicycle Suspension

Chris Mason — Wed, 28 Apr 2010 15:09:02 +0000

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 [...]

Fatigue & Durability Testing

James Wren — Wed, 17 May 2006 15:44:08 +0000

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 [...]

Non-Linear Calibration Curve And Polynomial

Dr Colin Mercer — Wed, 06 Jun 2001 16:17:01 +0000

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.

A very typical situation occurs with load-deflection tests such as non-linear springs, suspension systems, crush [...]
