The Single Station Jounce Tester is designed for vibration durability testing of automotive seat cushions and backrests. It evaluates the fatigue strength, wear resistance, and overall durability of seat components, including the frame, foam, and upholstery. This tester ensures realistic simulation of body weight and vibration loads without introducing excessive inertia, making it suitable for both seat components and complete seating systems.
Application
Applications of the Single Station Jounce Tester include, but are not limited to, the following fields:
Mechanical Manufacturing and Precision Manufacturing: Detection of runout error is a core indicator for measuring the quality of rotating parts, directly affecting the smoothness of equipment operation.
Industrial Inspection Equipment: Runout testers are used to detect the outer diameter, runout value, and out-of-roundness of workpieces such as metal shafts and rubber rollers.
Automated Production Lines: Runout testers are used in automated production lines to ensure the accuracy and stability of equipment.
Quality Control: Runout testers are used in quality control processes to detect and analyze the runout error of equipment, ensuring product quality.
Scientific Research and Development: Runout testers are used in scientific research and development to test and verify the performance and reliability of equipment.
Standards
QC/T 740-2017 – Automotive Seat Assembly Fatigue Test Standard
SAE J826-2002 – Anthropomorphic Test Devices for Vehicle Seats
Test Principle
The tester applies controlled vibration to the seat cushion and backrest at a set frequency and amplitude for a predetermined number of cycles. After testing:
Seat frame should remain intact with no cracks.
Foam and cushion should maintain their shape without deformation.
Upholstery should show no damage.
Maximum H-point variation remains within rated range.
Typical test setup:
Seat cushion: 100.000 vibration cycles at 100 times/minute.
Backrest: 50.000 vibration cycles at 100 times/minute.
