The Automotive Seat Dynamic Comfort Tester is designed to evaluate seat performance under dynamic conditions. It measures key parameters such as dynamic stiffness, natural frequency, damping ratio, and vibration transmissibility curves. These metrics help engineers and designers assess how a seat responds to vibrations and dynamic loads, providing essential insights into occupant comfort and seat performance under real-world driving conditions.
Application
(1) Automotive seat design and development
(2) Evaluation of seat dynamic comfort performance
(3) Quality control in automotive seat manufacturing
(4) Research on vibration behavior of seating systems
(5) Performance verification under simulated driving conditions
