The use of in-dummy measurement technology in vehicle crash testing has increased significantly in recent years. Leading OEMs and suppliers as well as national crash test centers in Europe rely on Kistler products and solutions for this. For instance Applus IDIADA’s passive safety department began using Kistler’s data acquisition technology for crash tests right from the conception at its site in Santa Oliva in Catalonia.
The introduction of THOR dummies means that crash test laboratories are required to process data across 120 data channels from one single dummy. Given the increasing number and complexity of the crash tests carried out today, the use of these types of dummies is almost impossible in many cases using traditional analog on-board DAS systems. The current trend, therefore, is moving towards measurement technology integrated directly into the dummies in order to exploit the available on-board systems for the vehicle sensors. This is one reason why IDIADA laboratory chose Kistler in-dummy measurement technology. The transition to DTI (Digital Transducer Interface) technology is based on confidence in a digital future with Kistler.
“Ongoing support and various on-site presentations managed to convince IDIADA of our innovative DTI technology”, says Alexander Schmitt, business driver for vehicle safety at Kistler. “Many customers follow activities in Europe with a focus on EuroNCAP (European New Car Assessment Program) laboratories with IDIADA being one of them. This is, therefore, a very important project for us.”
IDIADA has been working with Kistler for over 20 years and already uses several Kistler products from the vehicle safety area. In addition to Minidau®, it also uses the KiDAU® (Kistler Data Aquisition Unit). For the first time the plug part can be removed completely through the replaceable SD (Sensor Distribution) panel and replaced with a different attachment, meaning that no additional adapter cable is required. As well as improving the flexibility, time-saving qualities and user-friendliness of the application, this also minimizes the need for space in the vehicle.
