Summary:

AbstractA vehicle-mounted anti-vibration system is designed to semi-actively reduce accelerations acting on vibration isolation platform under different road conditions. To provide the basis for optimal anti-vibration design, the kinematics and dynamics of the platform are analyzed to investigate the relationship between leg length, strength, the platform position and vibration properties. As the platform is fixed on vehicle, a combined vehicle-platform model is necessary for verifying the performance and applying some suitable control algorithms. Also, typical digital testing roads will be built using road load spectrum. To optimize the platform parameters, especially stiffness and damping, an active control system is designed at first. An anti-vibration system including a semi-active inerter is designed to match the control forces which are calculated from the above active system. Finally, optimal anti-vibration system of the vehicle mounted platform which also considers the vehicle performances is done. Acceleration acting on the platform has been reduced. These results will be utilized for an intelligent active anti-vibration platform in future
