The crash sled and pedestrian protection equipment series covers a variety of test equipment required for vehicle passive safety development and regulatory testing, including the HyperG and SCAT crash sleds (sliding tables), the SBA rack, the CITR sled, the ALIS active lateral intrusion simulation system, the DITSH pedestrian protection headform launcher and the seat and headrest static strength test system SSS. It can both reproduce complex vehicle pulses and be used for regulatory standard testing.

The testing capability covers standards for seats (ECE R17-A9, R80-Ap1), seat belts (ECE R16-A8, FMVSS 208, AK-LV), headrests and whiplash (EuroNCAP, FMVSS 202a, RCAR-IIWPG 3), child restraint systems (ECE R44-A7, R129-A7 (Isofix), FMVSS 213, ADAC), battery REESS (ECE R100-A8C, LV124-M05, UN 38.3-T.4), roof load carriers (ISO 11154) and aircraft seats (SAE AS8049, FAR/CS 25.562).

Product Features

·Multi-form test platforms: covering test equipment of different loads and uses such as high-load sliding tables (HyperG), medium sliding tables (SCAT), multi-actuator racks (SBA) and headform launch tables (CITR)

·Regulatory standard testing: seat, seat belt, headrest whiplash, child restraint, battery, roof load carrier and aircraft seat tests can be carried out according to multiple standards such as ECE, FMVSS, EuroNCAP, ISO and SAE

·Modular configuration: CITR, DITSH and other equipment are fully modular, consisting of main structure, control system, launch module and additional components; customers can select options as needed and expand gradually as future needs arise

·Side-impact development capability: the ALIS active lateral intrusion simulation system can be used in combination with HyperG and SCAT sleds for side-impact test development

·Servo-electric technology: SSS adopts servo-electric actuators with closed-loop control, quieter, cleaner, maintenance-free and without the need for cooling devices

Main Products / Sub-products

HyperG crash sled

High-load crash sled (sliding table) with a nominal force of 2000 kN, maximum speed 90 km/h, rated working stroke 1700 mm, maximum payload 3000 kg and sliding table base dimensions L3500×W1500 mm; it can be configured with a servo-hydraulic braking device and combined with the ALIS system for side-impact test development.

SCAT crash sled

Medium crash sled (sliding table) with a nominal force of 1000 kN, maximum speed 80 km/h, rated working stroke 1300 mm, maximum payload 1500 kg, maximum overturning moment 172 kNm and sliding table base dimensions L2400×W1400 mm; it can be used for battery testing and other scenarios, and can also be combined with the ALIS system for side-impact test development.

SBA rack

Consisting of a structural rack, it can be fitted with up to nine actuators; the vertical ΔZ motion, lateral ΔY and vertical angle θY are all driven by motors, and the test load is controlled by closed loop; the standard actuator is an electromechanical cylinder, and hydraulic actuators can also be provided; the overall rack dimensions are W3300×D2300×H3100 mm; Type A maximum force (short-term peak) 35 kN @<=200 mm/s, Type B 40 kN @<=200 mm/s (50 kN hold <=10 s), maximum speed (short-term peak) 500 mm/s, stroke 1000 mm, and dynamic performance 30 kN @ 300 mm/s over full stroke.

CITR sled

Consisting of a test bench, control system, launch module and customer-optional additional components, the bench is usually fixed on a steel floor and has three degrees of freedom; it can be configured with the FMH purely pneumatic launcher or the FMH2 electro-pneumatic hybrid launcher (FMH2 maximum speed 42 km/h, maximum mass 7 kg, maximum impact energy 360 J, speed repeatability ±0.05 km/h, length 430 mm); when free-flight testing is not required, a guided impact (GI) or pendulum (PEN) attachment can be added in front of the launcher for headrest linear impact, headrest pendulum impact and other tests.

ALIS active lateral intrusion simulation system

It simulates the side-impact intrusion process through a high-dynamic actuator (such as the HDA22, 130 kN / 600 mm). The arrangement depends on the sled type and thrust, test purpose, working method and site layout: it can be combined with the sled system (with ALIS placed on or off the sliding table), where the sled creates the overall motion of the vehicle on the ground; it can also be used independently to simulate only the intrusion phase of a side impact.

DITSH pedestrian protection headform launcher

A modular launch system consisting of a main structure, control system, several modules and additional components, which customers can select themselves and purchase gradually as future needs arise; the main structure provides up to four degrees of freedom (lift stroke 1900~2800 mm, robotic arm covering the entire windshield 2100 mm, tower rotation approximately ±180°, and the base can be flush with the ground), and the tower rotation supports automatic conversion from equipment coordinates to prototype coordinates. It is configured with the PP-HYB module (maximum speed 65 km/h, maximum mass 55 kg, maximum impact energy 3400 J, speed repeatability ±0.05 km/h, rotation range -10°~+90°) or the FMH2 module (maximum speed 42 km/h, maximum mass 7 kg, maximum impact energy 360 J, length 430 mm), combining the high energy density of compressed air with the controllability of an electric linear motor; it can be used for impactor tests such as aPLI, FlexPLI, child/adult headform and R12 headform, and supports applications such as pedestrian protection headform launcher point plotting and false-touch testing in combination with an environmental chamber.

Seat and headrest static strength test system SSS

Consisting of a test platform and three seat stations (the base plate and seat sample are installed on a separate sample workbench); each station can be positioned in the Z (vertical, motor-driven), X (horizontal longitudinal) and Y (horizontal lateral) directions, and all support height-hold tests; seat backrest and headrest test loading is fully automatic, with closed-loop control by servo-electric actuators; backplate rated/maximum (short-term) static moment 3500/5000 Nm, headrest and height-hold rated/maximum (short-term) static force 2000/3400 N, back force sensor rated force 25 kN with accuracy 0.04%; it supports headrest top-surface detection and testing of samples with different back widths.
