Kistler enables digital measuring chains for advanced vehicle test stands

Faced with the challenge of modernizing its kinematics and compliance test machine for automotive engineering, AB Dynamics implemented the digital charge amplifier 5074A from Kistler. It enables a fully digital measuring chain including a set of load cells to measure tire forces and moments in real time.

Today’s cars are high-powered technology hubs, packed with mechatronic components that deliver ever-increasing levels of driver assistance; they can even perform some maneuvers autonomously. However, impressive features and functions such as these need to be supported by comprehensive testing with specialized equipment, backed by specific know-how. One leading provider of these resources is Anthony Best Dynamics Limited, a British company based in the picturesque town of Bradford on Avon in south-western England.

Many vehicle developers throughout the world operate one of AB Dynamics’ leading solutions: the Suspension Parameter Measuring Machine (SPMM), a complex test stand that can simulate a car’s behavior by applying combined roll, pitch, bounce, and yaw motions on a moving platform. Under each of the four wheel stations, a multicomponent force link set of piezoelectric load cells ensures accurate measurement of all forces and moments: the 9366CC series from Kistler is a customizable kit with four sensing elements that deliver maximum accuracy thanks to their high rigidity and natural frequency.
