Study of a Device for Controlling the Pulses of Sled Testing

摘要: Improving the effectiveness of restraint systems (seat belts, air bags,...) requires development experimental means capable testing different crash types. Sled offers advantage improving test conditions and consequently repeatability pulse. The paper focuses on deceleration device how to control sled. includes a fixed part composed four cylinders maintaining steel bar spur attached front dissipation mechanism is due plastic deformation impacted by spur. stationary, leading constant force therefore an study presents analytical numerical model (FE model) predict Comparisons between results predicted point out reliability models.
