A range of ‘intelligent’ biofidelic dummies is now available following a collaboration between specialist CTS and instrumentation developer Kistler Group.
According to the companies, the combination of CTS’s Primus dummies and Kistler’s high-precision measurement technology extends testing capability from road traffic accident (RTA) investigation to product development, operational training, and modeling and reconstruction. Marketed through the Kistler Group’s global sales network, the Primus biofidelic dummy is available with the option of individual in-body measurement technology and sensor instrumentation.
According to CTS, the dummy’s bones, ligaments and joints are closely modeled on those of humans, as are the weight distribution, skin and skeletal structure. As such, its manufacturers say it can be used for highly accurate reconstruction of accidents, not only in the automotive sector but also in other areas including aviation, safety engineering, product testing and recovery exercises for rescue services.
During operation, the dummy behaves like an unconscious person in both standing and sitting positions with no need for further modification. Force, acceleration, pressure and displacement digital sensor technology from Kistler can be fully integrated into the dummy without influencing performance, allowing autonomous data acquisition with just a single cable to the miniature datalogger installed in the chest area.
The developers say they focused particular attention on the structural design and the materials used in order to reproduce the effects of shock and pressure loads on the human body as realistically as possible while keeping the dummy repairable and reusable.
