Vehicle vibration is the main cause of back pain and other whole-body vibration (WBV) syndrome of professional bus/truck drivers. Except back pain, the WBV syndrome may have a series of consequences, including muscle fatigue, spinal column disease, digestive system diseases and other cardiovascular system effects (hyperventilation, increased heart rate, oxygen intake, pulmonary ventilation and respiratory rate etc). As news reported in HK recently, 94% of professional drivers of land transport suffered from occupational injury and more than 30% have at least one kind of sciatica. 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. However, existing seating technology has at least one of the following drawbacks: (1) the resonant frequency is much higher than 1 Hz; (2) the tolerant vibration displacement is very small; (3) unsatisfactory damping system is adopted; (3) the cost is expensive. New technical innovation is therefore expected.


Our invention adopts a cutting-edge nonlinear vibration control theory and method recently developed. 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. 


  • 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.
  • Better performance with stronger vibration.
