ECE R 21 FMVSS201 Pendulum The stand alone solution for instrument panel similar impact testing  High stiffness pendulum structure (CAE optimized) for low vibration  Excellent accuracy by rotating nitrogen piston  No hydraulics means low maintenance cost minimum downtime  Low operating cost ($1/Launch)  Robust design for extended life and high reliability  Fully controlled by Microsys SureFire Software ECE R 21 FMVSS201 Pendulum System Description: Movement of System: The pendulum system is designed to support the development of instru- Y Z ment panels or similar energy absorbing elements like seats, headliners and center-consols according to the regulations ECE-R21 and FMVSS 201. The acceleration of the ball head is measured by an accelerometer and evaluated against the test criteria of max. acceleration over 3 msec 80g. X The system is propelled by a rotating piston powered by nitrogen. The advantage of using a rotating piston is a constant acceleration and therefore a higher speed accuracy than a linear driven pendulum.  X-direction possible on Customer request The high stiffness of the impactor allows for excellent correlation to the CAE results of pendulum tests with very low harmonic noise.  Y-direction 2500 mm / accuracy 0.1 mm A simulation model of the pendulum is available for customers.  Z-direction 1000 mm / accuracy 0.1 mm (All Travel can be modified to customer request) Basic System Specifi
