Abstract
A test device for acceleration sensors comprises a low-friction carriage in articular supported by an air cushion. A drive is coupled to the carriage for producing a predetermined acceleration course of the carriage and a test object secured thereto. A direct pneumatic drive is provided at the carriage and has at least one piston and at least one cylinder defining an air space. A control device is arranged upstream of the air space and adapted to cause a pressure course in the air space corresponding to the desired acceleration course.
