Winterthur, February 2018 – Reliable tests and cutting-edge measurement technology provide the essential basis for optimum vehicle development and engineering. Test configurations must be simplified as far as possible to ensure complete and reliable acquisition of the measurement data. Improved measurement results, lower material costs and shorter test times: these are the benefits that Kistler's DTI technology with its 'One cable for everything' concept can deliver, in vehicle safety testing, vehicle dynamics and durability tests.
Because precise measurements are the top priority in vehicle tests, the test configurations and equipment have to meet demanding requirements. Especially when it comes to vehicle safety, crash tests deliver in-depth knowledge about the behavior of a vehicle and its components, and they also show how a collision can potentially impact the vehicle's occupants. Series of tests to verify vehicle safety use crash test dummies, in which specially produced sensors are installed. Before, during and after a collision involving the test vehicle, these sensors capture data that provides important information about the vehicle's safety.
As vehicles become more complex and the level of digitization in automobiles increases, more and more onboard and in-dummy measuring channels are needed. Back in the early 1990s, up to 250 analog measuring channels were processed in collision tests – but now the number of sensors required is often more than 600. Another factor: less and less space is available to install the sensors. Because more analog sensors are used to measure the various test parameters, more cables have to be installed to supply power and transmit data. The end result is that test setup is becoming extremely time-consuming and cost-intensive. In addition, the large number of input channels increases the risk of errors or omissions in data acquisition.
