Problem addressed

Vehicle vibration is the main cause of back pain and other whole-body vibration (WBV) syndrome of professional bus/truck drivers. Therefore, a cost-effective high-performance anti-vibration seat matters not only to the health of professional drivers but also to the traffic and operation safety.

  • The main working part relies only on passive structural designs. The anti-vibration system can achieve a quasi-zero stiffness in the vertical direction such that the seat cushion can be maintained at its stable level with almost no influence from the bottom vibration.
  • The achieved damping effect can be automatically changed with vibration level such that strong vibration from the bottom can be suppressed effectively while high frequency vibration will be completely isolated and not produce a “stiff” effect.
  • When vibration is stronger or payload is bigger, such special nonlinear effects can become even better, demonstrating a completely different and advantageous vibration control performance compared to all market products.
Key impact
  • Resonant frequency can be tuned to around or smaller than 1 Hz.
  • Vibration isolation can be seen clearly at 2 Hz.
  • Very reliable and endurable structural design.
  • Very cheap manufacturing cost.
