摘要：
A multi-degree-of-freedom seating system platform based on the cubic Stewart parallel mechanism is designed for vibration control of an off-road vehicle drivers seat. A parameter sensitivity analysis is conducted to identify the most sensitive parameters for the transmissibility ratio of the seating system platform. Then, a vibration control method combining active and passive control for each branch of the seat platform leg is developed to reduce the drivers body vibration. The results indicate that the seating system platform designed in this article can reduce the vibration in the vertical direction, horizontal direction and roll direction simultaneously through passive vibration control. The vibration can be further reduced in these three directions by adding active vibration control.
