Automobile seat belt locking performance tester
Compliance Standards
- FMVSS 209 (Seat Belt Assemblies)
- ECE R16 (Safety Belt Requirements)
- ISO 13046 (Road Vehicle Seat Belt Testing)
- GB 14166 (China Seat Belt Standard)
JIS D4604 (Japanese Industrial Standard)
Main parameters:
Control system:
PLC control system is usually used to realize automatic control and data processing.
Operation interface:
It is equipped with a color touch screen and supports switching between Chinese and English for easy operation.
Emergency lock test parameters:
After installation, the winder can reach a speed of 2.94m/s within 50ms to simulate the locking function in emergency situations.
Angle adjustment:
The installation Angle can be adjusted, such as the winding shaft to the horizontal plane of 45°, 90°, 135° and 180° to adapt to different test requirements.
Vehicle acceleration adjustment range:
The acceleration adjustment range is usually 0.2——1.5g （can be set） to meet the needs of different test conditions.
Acceleration adjustment step:
The acceleration adjustment step is usually less than or equal to 0.05g to ensure the accuracy of the test.
Maximum displacement of car feeling:
The maximum displacement of the car is usually 100mm, which is used to simulate the displacement of the vehicle during an emergency stop or collision.
Inductive acceleration adjustment range:
The inductive acceleration adjustment range is not less than 0.2——2.5g to adapt to the test needs of different seat belt materials.
Acceleration measurement accuracy:
The measurement accuracy of acceleration is usually less than 0.01g to ensure the accuracy of the test results.
Repeatability deviation of acceleration:
The repeatability deviation of acceleration is usually less than or equal to ±0.01g to ensure the stability and reliability of the test results.
Maximum overshoot of acceleration:
The maximum overshoot of the acceleration is usually less than 10% of the set acceleration value to ensure the accuracy of the test.
Seatbelt locking distance measurement accuracy:
Seat belt lock distance measurement accuracy is usually less than or equal to ±0.01mm, to ensure the accuracy of the test results.
