Passive Safety Testing

IST has engineered a series of passive safety testing rigs to meet different FMVSS and ECE regulations. All of the passive safety testing rigs are fully integrated with IST's digital Labtronic™ controller and Windows^® software suite.

• Occupant Impact Testing System
• Head Restraint Test Rig
• Seat Belt Anchorage Testing
• Pedestrian Impact Test System

IST has engineered a versatile passive safety testing system which meets the requirements for pendulum headform impact and torso-launch testing. Each configuration can be supplied separately or in one multi-functional rig.

• Meets FMVSS 203 and ECE regulation 12.
• With addition of pendulum frame it also meets FMVSS 201 and ECE regulation 14.
• Utilizes a catapult actuator for precise, repeatable control of impact velocity.
• Digitally integrated with IST's Labtronic 8800 controller and Windows software suite.
• Standard bodyforms and instrumented headforms.

• Precise, repeatable control of the hydraulic actuator via IST's Labtronic controller and Windows software suite.
• Easily adjustable 'H' point.
• Precise control and acquisition of applied load from fatigue rated IST load cell.
• Narrow rig design to allow two or more systems to act side by side.
• System can be provided with a stand alone hydraulic power supply or integrated into an existing ringmain.

IST has designed a versatile new passive safety testing system which can be configured from single axis - single seat anchorage test through to nine axes - two seat, lap belt and shoulder belt test. The high rate option allows the specified load to be reached in as little as 0.15 seconds while the standard option will achieve load within 2 seconds.

• Vertical and horizontal adjustment ranges for cars, mpv's and trucks.
• Up to nine, 1000 mm stroke actuators.
• Two loading rate options are available for FMVSS and ECE compliance.
• Digitally integrated with IST's Labtronic 8800 controller and Windows software suite.
• Standard fixtures available for lap and torso belts.

The IST pedestrian impact test system is designed to meet the EEVC Working Group 10 Report recommendations for the evaluation of pedestrian protection methods for passenger cars. The system allows tests to be conducted on vehicle bumpers, hood (bonnet) and vehicle leading edge by accelerating either a legform impactor, upper legform impactor or headform impactor at speeds of up to 40km/h. The legform and headform impactors are accelerated to the required velocity using a hydraulic actuator operating under closed loop control. The impactor is then released at the test velocity for 'free flight' impact on the vehicle.

• The Hydropuls™ actuator is equipped with hydrostatic bearings for the piston rod which makes it extremely insensitive to the influence of side loads. Furthermore, with the hydrostatic bearing, the piston rod is constantly sliding on an oil film, i.e. the actuator works nearly without friction and without wear.
• The test rig is controlled by the Labtronic 8800. The control of test sequences is done via PC.
• A simulation software enables the operator to generate a freely definable velocity drive signal for the impactor.
• The position of the Hydropuls actuator (x,y,z and vertical angle of impact) is adjusted electromechanically via a separate control panel.
• The hydraulic energy, which is necessary for the tests, is provided by two hydraulic accumulators which are mounted directly to the actuator.
