The Strain Gauge Goniometer, a New Sensor to Measure Dummy Joint Angles Under Crash Condition

摘要

The paper describes the use of strain gauge goniometers to measure dummy leg joint angles in impact tests. The instruments have been developed based on regular goniometers used for human gait analysis. Specific modifications enhanced the mechanical stability and the electrical insulation of the sensors. They are now compatible with standard crash data acquisition systems. Several vehicle crash tests have been analyzed using the Goniometers as a supplementary measurement device. Due to its low weight, the device does not significantly Alter the dummy behavior. Further areas of application Are outlined in the paper.
