Car seat dynamic comfort tester

Applicable standards:

QC/T 55-1993 "Test Standards and Methods for Dynamic Seat comfort" : This standard specifies the test items, test equipment, test procedures and data processing methods of dynamic seat comfort test. It is the main reference for the design, manufacture and use of the dynamic comfort tester for car seats

Main parameters:

Vertical displacement: usually expressed as the maximum moving distance of the tester in the vertical direction, generally about 200mm. This parameter determines the seat vibration amplitude that the tester can simulate.

Vertical frequency: The vibration frequency range of the tester in the vertical direction, usually 0.5——20Hz. This parameter reflects the range of seat vibration frequencies that the tester is able to simulate and is critical for evaluating the seat's comfort at different frequencies.

Displacement amplifier: The tester is usually equipped with a displacement amplifier to adjust the vibration amplitude. The common displacement amplifier gear is 100%, 50%, 20%, etc., and the accuracy is ±1%FS of the full range （from 20% of the full range）。

Acceleration range: The maximum acceleration value that the tester can measure, generally about 5g （5 times the acceleration of gravity）。 This parameter determines the ability of the tester to simulate high acceleration vibration.

Acceleration sensitivity: The degree to which the tester is sensitive to changes in acceleration, usually less than 5%. This parameter affects the accuracy and reliability of the measurement results of the tester.

Vibration table speed: The maximum moving speed of the tester vibration table, generally about 1.3m/s. This parameter determines the response speed of the tester when simulating seat vibration.

Maximum load: The maximum weight that the tester can carry, usually about 150kg. This parameter determines the type and size range of seats that the tester can test.
