Monitoring lifetime of vehicle components - involves continuously measuring and monitoring load on components with strain gauges feeding evaluation unit

摘要

The components carry electrical load transducers in regions of high loading. The transducer measurement values are fed to an evaluation unit throughout vehicle travel and are stored. The summed measurement values are continuously evaluated to determine the maximum load capability. Strain gauges can be used as the electrical load transducers. The evaluation u i is combined with a display device for the driver which gives an indication when the maximum load limit of the components is reached. USE/ADVANTAGE - Esp. for monitoring lifetime of motor vehicle suspension parts. method enables detection of when safety falls below defined safety level.
