SmartCrash barriers
Kistler has worked for many years on dynamic crash measurement in experimental developments and in the domain of passive safety and is today the market leader for crash barriers. The latest generation of SmartCrash barriers (Typ 9655A...) represents the state of the art in this field: 3-component force measurement; integrated data recording, storage and digitalisation in each individual force measurement element; a connection cable for each SmartCrash segment, with up to 100 individual force measurement elements; SmartCrash barriers made up from a number of SmartCrash segments. Piezoelectric measurement technology is the perfect tool for dynamic measurement in crash testing and the latest generation of SmartCrash barriers is being used successfully by major automobile manufacturers.
The MICRODAU design contains 16 MB flash storage for local data storage for each 3-channel DAQ module. The storage capacity is sufficient for data recorded at a sampling rate of 20 kHz over a period of up to 150 seconds. Combined with local data storage, the USB bus provides synchronized data recording on all channels without needing large bandwidth for data transmission. Thanks to electrical reinforcement, three measuring domains (e.g. 5%, 20% and 100% of the full range) can be switched at the charge amplifier. This means that, in combination with the high linearity of the quartz sensors, the measuring range is increased by several powers of ten.
All of Kistler's crash standards and special solutions provide for easy handling. Depending on the customer's particular requirements, the SmartCrash barriers can be segmented and produced in various sizes. Front-end fixing of the whole SmartCrash barrier permits faster and easier changes between the individual crash standards (e.g. EuroNCAP, US NCAP, J NCAP, TRL and AZT).
