​​​​​​​· Apply force to the front edge of the vertical plane direction: 0~1000N (≥1min);
​​​​​​​· Heating cushion bending times: 0~999999 times, can be set;
​​​​​​​· The surface of the seat ring is evenly applied with force: 0~3000N (4s,20000 times), the thickness of the rubber load pad is ≥10mm, the diameter is ≥300mm, the Shore hardness is ≥70, the assembly thickness of the load pad is ≥5mm, and the diameter of the steel disc is ≥300mm;
​​​​​​​· Apply force evenly on the side of the seat (both sides): 0~1000N (≥1s, ≥10000 times, interval 0.5s, apply force alternately on both sides for a total of one cycle), rubber load pad thickness ≥19mm, diameter ≥76mm, Shore hardness ≥70;
​​​​​​​· Timing: 0~999999 seconds, can be set, timing accuracy 0.1 seconds, resolution 0.01 seconds.

3. Position adjustment range of electric cylinder
​​​​​​​· One set of motor + precision screw rod device + manual moving pulley is adopted in XY2 direction, and the position is adjusted by clicking button, and the adjustment range is ±400mm.
4. Materials and structure
​​​​​​​· The structural frame adopts 80mm*80mm aluminum profile as the theme, the base plate is made of carbon steel spray plastic, and the connectors are made of aluminum alloy.
5. Safety and environmental protection
​​​​​​​· Protection function: overheating protection, phase loss protection, short circuit protection and other safety protection measures.
​​​​​​​· According to industry standards and national standards, the noise of equipment is less than or equal to 75dB (measured at a distance of 1-1.5 meters from the noise source).
3. Conditions of use

Iv. Working Principle
The equipment is equipped with four electric cylinder systems on the left, right, top, and front to apply loading forces in four directions. Additionally, it features a mechanism on the right side for lifting and lowering the seat cover and seat cushion, enabling opening/closing tests of these components. To ensure perpendicular alignment between the force application area and the load-bearing area, the system allows vertical adjustment along the Z-axis and enables rotational fine-tuning within the force measurement plane.
V. Software functions
​​​​​​​· Real-time monitoring: loading force and loading time curve data
​​​​​​​· Remote operation: support computer terminal to view the running status, alarm prompt and emergency brake
​​​​​​​· Secondary development: free assistance for software customization during warranty period
VI. Main configuration list
VII. Appendix
​​​​​​​· Equipment information: provide operation manual, original factory commissioning report, equipment instruction manual (the instruction manual should include use, daily maintenance and repair instructions).
​​​​​​​· Dedault and error prevention of electrical interlock: there is reliable protection against electric shock, no safety risk of external contact.
